SCons.Builder
Builder object subsystem.
A Builder object is a callable that encapsulates information about how
to execute actions to create a target Node (file) from source Nodes
(files), and how to create those dependencies for tracking.
The main entry point here is the Builder() factory method. This provides
a procedural interface that creates the right underlying Builder object
based on the keyword arguments supplied and the types of the arguments.
The goal is for this external interface to be simple enough that the
vast majority of users can create new Builders as necessary to support
building new types of files in their configurations, without having to
dive any deeper into this subsystem.
The base class here is BuilderBase. This is a concrete base class which
does, in fact, represent the Builder objects that we (or users) create.
There is also a proxy that looks like a Builder:
CompositeBuilder
This proxies for a Builder with an action that is actually a
dictionary that knows how to map file suffixes to a specific
action. This is so that we can invoke different actions
(compilers, compile options) for different flavors of source
files.
Builders and their proxies have the following public interface methods
used by other modules:
- __call__()
THE public interface. Calling a Builder object (with the
use of internal helper methods) sets up the target and source
dependencies, appropriate mapping to a specific action, and the
environment manipulation necessary for overridden construction
variable. This also takes care of warning about possible mistakes
in keyword arguments.
- add_emitter()
Adds an emitter for a specific file suffix, used by some Tool
modules to specify that (for example) a yacc invocation on a .y
can create a .h *and* a .c file.
- add_action()
Adds an action for a specific file suffix, heavily used by
Tool modules to add their specific action(s) for turning
a source file into an object file to the global static
and shared object file Builders.
There are the following methods for internal use within this module:
- _execute()
The internal method that handles the heavily lifting when a
Builder is called. This is used so that the __call__() methods
can set up warning about possible mistakes in keyword-argument
overrides, and *then* execute all of the steps necessary so that
the warnings only occur once.
- get_name()
Returns the Builder's name within a specific Environment,
primarily used to try to return helpful information in error
messages.
- adjust_suffix()
- get_prefix()
- get_suffix()
- get_src_suffix()
- set_src_suffix()
Miscellaneous stuff for handling the prefix and suffix
manipulation we use in turning source file names into target
file names.

This method is called from multiple threads in a parallel build,

if the user requested a no_exec (-n) build, then
SCons.Action.execute_actions is set to 0 and when any action
is called, it does its showing but then just returns zero
instead of actually calling the action execution operation.
The problem for caching is that if the file does NOT exist in
cache then the CacheRetrieveString won't return anything to
show for the task, but the Action.__call__ won't call
CacheRetrieveFunc; instead it just returns zero, which makes
the code below think that the file *was* successfully
retrieved from the cache, therefore it doesn't do any
subsequent building. However, the CacheRetrieveString didn't
print anything because it didn't actually exist in the cache,
and no more build actions will be performed, so the user just
sees nothing. The fix is to tell Action.__call__ to always
execute the CacheRetrieveFunc and then have the latter
explicitly check SCons.Action.execute_actions itself.

"""Autoconf-like configuration support
The purpose of this module is to define how a check is to be performed.
A context class is used that defines functions for carrying out the tests,
logging and messages. The following methods and members must be present:
context.Display(msg)
Function called to print messages that are normally displayed
for the user. Newlines are explicitly used. The text should
also be written to the logfile!
context.Log(msg)
Function called to write to a log file.
context.BuildProg(text, ext)
Function called to build a program, using "ext" for the file
extension. Must return an empty string for success, an error
message for failure. For reliable test results building should
be done just like an actual program would be build, using the
same command and arguments (including configure results so far).
context.CompileProg(text, ext)
Function called to compile a program, using "ext" for the file
extension. Must return an empty string for success, an error
message for failure. For reliable test results compiling should be
done just like an actual source file would be compiled, using the
same command and arguments (including configure results so far).
context.AppendLIBS(lib_name_list)
Append "lib_name_list" to the value of LIBS. "lib_namelist" is
a list of strings. Return the value of LIBS before changing it
(any type can be used, it is passed to SetLIBS() later.)
context.PrependLIBS(lib_name_list)
Prepend "lib_name_list" to the value of LIBS. "lib_namelist" is
a list of strings. Return the value of LIBS before changing it
(any type can be used, it is passed to SetLIBS() later.)
context.SetLIBS(value)
Set LIBS to "value". The type of "value" is what AppendLIBS()
returned. Return the value of LIBS before changing it (any type
can be used, it is passed to SetLIBS() later.)
context.headerfilename
Name of file to append configure results to, usually "confdefs.h".
The file must not exist or be empty when starting. Empty or None
to skip this (some tests will not work!).
context.config_h (may be missing).
If present, must be a string, which will be filled with the
contents of a config_h file.
context.vardict
Dictionary holding variables used for the tests and stores results
from the tests, used for the build commands. Normally contains
"CC", "LIBS", "CPPFLAGS", etc.
context.havedict
Dictionary holding results from the tests that are to be used
inside a program. Names often start with "HAVE_". These are zero
(feature not present) or one (feature present). Other variables
may have any value, e.g., "PERLVERSION" can be a number and
"SYSTEMNAME" a string.

"""Decorator-based memoizer to count caching stats.
A decorator-based implementation to count hits and misses of the computed
values that various methods cache in memory.
Use of this modules assumes that wrapped methods be coded to cache their
values in a consistent way. In particular, it requires that the class uses a
dictionary named "_memo" to store the cached values.
Here is an example of wrapping a method that returns a computed value,
with no input parameters::
@SCons.Memoize.CountMethodCall
def foo(self):
try: # Memoization
return self._memo['foo'] # Memoization
except KeyError: # Memoization
pass # Memoization
result = self.compute_foo_value()
self._memo['foo'] = result # Memoization
return result
Here is an example of wrapping a method that will return different values
based on one or more input arguments::
def _bar_key(self, argument): # Memoization
return argument # Memoization
@SCons.Memoize.CountDictCall(_bar_key)
def bar(self, argument):
memo_key = argument # Memoization
try: # Memoization
memo_dict = self._memo['bar'] # Memoization
except KeyError: # Memoization
memo_dict = {} # Memoization
self._memo['dict'] = memo_dict # Memoization
else: # Memoization
try: # Memoization
return memo_dict[memo_key] # Memoization
except KeyError: # Memoization
pass # Memoization
result = self.compute_bar_value(argument)
memo_dict[memo_key] = result # Memoization
return result
Deciding what to cache is tricky, because different configurations
can have radically different performance tradeoffs, and because the
tradeoffs involved are often so non-obvious. Consequently, deciding
whether or not to cache a given method will likely be more of an art than
a science, but should still be based on available data from this module.
Here are some VERY GENERAL guidelines about deciding whether or not to
cache return values from a method that's being called a lot:
-- The first question to ask is, "Can we change the calling code
so this method isn't called so often?" Sometimes this can be
done by changing the algorithm. Sometimes the *caller* should
be memoized, not the method you're looking at.
-- The memoized function should be timed with multiple configurations
to make sure it doesn't inadvertently slow down some other
configuration.
-- When memoizing values based on a dictionary key composed of
input arguments, you don't need to use all of the arguments
if some of them don't affect the return values.

in the module namespace, but putting it in this class allows us to
use the same Memoizer pattern that we use elsewhere to count cache
hits and misses, which is very valuable.
Lookup keys in the cache are computed by the _PathList_key() method.
Cache lookup should be quick, so we don't spend cycles canonicalizing
all forms of the same lookup key. For example, 'x:y' and ['x',
'y'] logically represent the same list, but we don't bother to
split string representations and treat those two equivalently.
(Note, however, that we do, treat lists and tuples the same.)
The main type of duplication we're trying to catch will come from

"""SCons platform selection.
Looks for modules that define a callable object that can modify a
construction environment as appropriate for a given platform.
Note that we take a more simplistic view of "platform" than Python does.
We're looking for a single string that determines a set of
tool-independent variables with which to initialize a construction
environment. Consequently, we'll examine both sys.platform and os.name
(and anything else that might come in to play) in order to return some
specification which is unique enough for our purposes.
Note that because this subsystem just *selects* a callable that can
modify a construction environment, it's possible for people to define
their own "platform specification" in an arbitrary callable function.
No one needs to use or tie in to this subsystem in order to roll
their own platform definition.

env["TEMPFILE"] = TempFileMunge

By default, the name of the temporary file used begins with a

setting the TEMPFILEPREFIX variable. Example::
env["TEMPFILEPREFIX"] = '-@' # diab compiler
env["TEMPFILEPREFIX"] = '-via' # arm tool chain
env["TEMPFILEPREFIX"] = '' # (the empty string) PC Lint
You can configure the extension of the temporary file through the
TEMPFILESUFFIX variable, which defaults to '.lnk' (see comments
in the code below). Example::
env["TEMPFILESUFFIX"] = '.lnt' # PC Lint
Entries in the temporary file are separated by the value of the

# USE mod_a ! ; USE mod_b [in-line comment of second USE statement]
#
# the second module name (mod_b) will be picked up as a dependency
# even though it should be ignored. The only way I can see
# to rectify this would be to modify the scanner to eliminate
# the call to re.findall, read in the contents of the file,
# treating the comment character as an end-of-line character
# in addition to the normal linefeed, loop over each line,
# weeding out the comments, and looking for the USE statements.
# One advantage to this is that the regex passed to the scanner
# would no longer need to match a semicolon.
#
# -- I question whether or not we need to detect dependencies to
# INTRINSIC modules because these are built-in to the compiler.
# If we consider them a dependency, will SCons look for them, not
# find them, and kill the build? Or will we there be standard
# compiler-specific directories we will need to point to so the
# compiler and SCons can locate the proper object and mod files?
# Here is a breakdown of the regex:
#
# (?i) : regex is case insensitive
# ^ : start of line
# (?: : group a collection of regex symbols without saving the match as a "group"
# ^|; : matches either the start of the line or a semicolon - semicolon
# ) : end the unsaved grouping
# \s* : any amount of white space
# USE : match the string USE, case insensitive
# (?: : group a collection of regex symbols without saving the match as a "group"
# \s+| : match one or more whitespace OR .... (the next entire grouped set of regex symbols)
# (?: : group a collection of regex symbols without saving the match as a "group"
# (?: : establish another unsaved grouping of regex symbols
# \s* : any amount of white space
# , : match a comma
# \s* : any amount of white space
# (?:NON_)? : optionally match the prefix NON_, case insensitive
# INTRINSIC : match the string INTRINSIC, case insensitive
# )? : optionally match the ", INTRINSIC/NON_INTRINSIC" grouped expression
# \s* : any amount of white space
# :: : match a double colon that must appear after the INTRINSIC/NON_INTRINSIC attribute
# ) : end the unsaved grouping
# ) : end the unsaved grouping
# \s* : match any amount of white space
# (\w+) : match the module name that is being USE'd
#
#
use_regex = r"(?i)(?:^|;)\s*USE(?:\s+|(?:(?:\s*,\s*(?:NON_)?INTRINSIC)?\s*::))\s*(\w+)"
# The INCLUDE statement regex matches the following:
#
# INCLUDE 'some_Text'
# INCLUDE "some_Text"
# INCLUDE "some_Text" ; INCLUDE "some_Text"
# INCLUDE kind_"some_Text"
# INCLUDE kind_'some_Text"
#
# where some_Text can include any alphanumeric and/or special character
# as defined by the Fortran 2003 standard.
#
# Limitations:
#
# -- The Fortran standard dictates that a " or ' in the INCLUDE'd
# string must be represented as a "" or '', if the quotes that wrap
# the entire string are either a ' or ", respectively. While the
# regular expression below can detect the ' or " characters just fine,
# the scanning logic, presently is unable to detect them and reduce
# them to a single instance. This probably isn't an issue since,
# in practice, ' or " are not generally used in filenames.
#
# -- This regex will not properly deal with multiple INCLUDE statements
# when the entire line has been commented out, ala
#
# ! INCLUDE 'some_file' ; INCLUDE 'some_file'
#
# In such cases, it will properly ignore the first INCLUDE file,
# but will actually still pick up the second. Interestingly enough,
# the regex will properly deal with these cases:
#
# INCLUDE 'some_file'
# INCLUDE 'some_file' !; INCLUDE 'some_file'
#
# To get around the above limitation, the FORTRAN programmer could
# simply comment each INCLUDE statement separately, like this
#
# ! INCLUDE 'some_file' !; INCLUDE 'some_file'
#
# The way I see it, the only way to get around this limitation would
# be to modify the scanning logic to replace the calls to re.findall
# with a custom loop that processes each line separately, throwing
# away fully commented out lines before attempting to match against
# the INCLUDE syntax.
#
# Here is a breakdown of the regex:
#
# (?i) : regex is case insensitive
# (?: : begin a non-saving group that matches the following:
# ^ : either the start of the line
# | : or
# ['">]\s*; : a semicolon that follows a single quote,
# double quote or greater than symbol (with any
# amount of whitespace in between). This will
# allow the regex to match multiple INCLUDE
# statements per line (although it also requires
# the positive lookahead assertion that is
# used below). It will even properly deal with
# (i.e. ignore) cases in which the additional
# INCLUDES are part of an in-line comment, ala
# " INCLUDE 'someFile' ! ; INCLUDE 'someFile2' "
# ) : end of non-saving group
# \s* : any amount of white space
# INCLUDE : match the string INCLUDE, case insensitive
# \s+ : match one or more white space characters
# (?\w+_)? : match the optional "kind-param _" prefix allowed by the standard
# [<"'] : match the include delimiter - an apostrophe, double quote, or less than symbol
# (.+?) : match one or more characters that make up
# the included path and file name and save it
# in a group. The Fortran standard allows for
# any non-control character to be used. The dot
# operator will pick up any character, including
# control codes, but I can't conceive of anyone
# putting control codes in their file names.
# The question mark indicates it is non-greedy so
# that regex will match only up to the next quote,
# double quote, or greater than symbol
# (?=["'>]) : positive lookahead assertion to match the include
# delimiter - an apostrophe, double quote, or
# greater than symbol. This level of complexity
# is required so that the include delimiter is
# not consumed by the match, thus allowing the
# sub-regex discussed above to uniquely match a
# set of semicolon-separated INCLUDE statements
# (as allowed by the F2003 standard)
include_regex = r"""(?i)(?:^|['">]\s*;)\s*INCLUDE\s+(?:\w+_)?[<"'](.+?)(?=["'>])"""

"""Class for scanning LaTeX files for included files.
Unlike most scanners, which use regular expressions that just
return the included file name, this returns a tuple consisting
of the keyword for the inclusion ("include", "includegraphics",
"input", or "bibliography"), and then the file name itself.
Based on a quick look at LaTeX documentation, it seems that we
should append .tex suffix for the "include" keywords, append .tex if
there is no extension for the "input" keyword, and need to add .bib
for the "bibliography" keyword that does not accept extensions by itself.
Finally, if there is no extension for an "includegraphics" keyword
latex will append .ps or .eps to find the file, while pdftex may use .pdf,
.jpg, .tif, .mps, or .png.
The actual subset and search order may be altered by
DeclareGraphicsExtensions command. This complication is ignored.
The default order corresponds to experimentation with teTeX::
$ latex --version
pdfeTeX 3.141592-1.21a-2.2 (Web2C 7.5.4)
kpathsea version 3.5.4
The order is:
['.eps', '.ps'] for latex
['.png', '.pdf', '.jpg', '.tif'].
Another difference is that the search path is determined by the type
of the file being searched:
env['TEXINPUTS'] for "input" and "include" keywords
env['TEXINPUTS'] for "includegraphics" keyword
env['TEXINPUTS'] for "lstinputlisting" keyword
env['BIBINPUTS'] for "bibliography" keyword
env['BSTINPUTS'] for "bibliographystyle" keyword
env['INDEXSTYLE'] for "makeindex" keyword, no scanning support needed just allows user to set it if needed.

skeys: an optional list argument that can be used

path_function: a function that takes four or five arguments
(a construction environment, Node for the directory
containing the SConscript file that defined the primary
target, list of target nodes, list of source nodes, and
optional argument for this instance) and returns a tuple
of the directories that can be searched for implicit
dependency files. May also return a callable() which
is called with no args and returns the tuple (supporting
Bindable class).
node_class: the class of Nodes which this scan will return.
If node_class is None, then this scanner will not enforce
any Node conversion and will return the raw results from
the underlying scanner function.
node_factory: the factory function to be called to
translate the raw results returned by the scanner function
into the expected node_class objects.
scan_check: a function to be called to first check whether
this node really needs to be scanned.
recursive: specifies that this scanner should be invoked
recursively on all of the implicit dependencies it returns
(the canonical example being #include lines in C source
files). May be a callable, which will be called to filter
the list of nodes found to select a subset for recursive
scanning (the canonical example being only recursively

# TODO:
#
# This has the potential to grow into something with a really big life
# of its own, which might or might not be a good thing. Nevertheless,
# here are some enhancements that will probably be requested some day
# and are worth keeping in mind (assuming this takes off):
#
# - A command to re-read / re-load the SConscript files. This may
# involve allowing people to specify command-line options (e.g. -f,
# -I, --no-site-dir) that affect how the SConscript files are read.
#
# - Additional command-line options on the "build" command.
#
# Of the supported options that seemed to make sense (after a quick
# pass through the list), the ones that seemed likely enough to be
# used are listed in the man page and have explicit test scripts.
#
# These had code changed in Script/Main.py to support them, but didn't
# seem likely to be used regularly, so had no test scripts added:
#
# build --diskcheck=*
# build --implicit-cache=*
# build --implicit-deps-changed=*
# build --implicit-deps-unchanged=*
#
# These look like they should "just work" with no changes to the
# existing code, but like those above, look unlikely to be used and
# therefore had no test scripts added:
#
# build --random
#
# These I'm not sure about. They might be useful for individual
# "build" commands, and may even work, but they seem unlikely enough
# that we'll wait until they're requested before spending any time on
# writing test scripts for them, or investigating whether they work.
#
# build -q [??? is there a useful analog to the exit status?]
# build --duplicate=
# build --profile=
# build --max-drift=
# build --warn=*
# build --Y
#
# - Most of the SCons command-line options that the "build" command
# supports should be settable as default options that apply to all
# subsequent "build" commands. Maybe a "set {option}" command that
# maps to "SetOption('{option}')".
#
# - Need something in the 'help' command that prints the -h output.
#
# - A command to run the configure subsystem separately (must see how
# this interacts with the new automake model).
#
# - Command-line completion of target names; maybe even of SCons options?
# Completion is something that's supported by the Python cmd module,
# so this should be doable without too much trouble.

"""
Holder class for uniform access to SCons options, regardless
of whether or not they can be set on the command line or in the
SConscript files (using the SetOption() function).
A SCons option value can originate three different ways:
1) set on the command line;
2) set in an SConscript file;
3) the default setting (from the the op.add_option()
calls in the Parser() function, below).
The command line always overrides a value set in a SConscript file,
which in turn always overrides default settings. Because we want
to support user-specified options in the SConscript file itself,
though, we may not know about all of the options when the command
line is first parsed, so we can't make all the necessary precedence
decisions at the time the option is configured.
The solution implemented in this class is to keep these different sets
of settings separate (command line, SConscript file, and default)
and to override the __getattr__() method to check them in turn.
This should allow the rest of the code to just fetch values as
attributes of an instance of this class, without having to worry
about where they came from.
Note that not all command line options are settable from SConscript
files, and the ones that are must be explicitly added to the
"settable" list in this class, and optionally validated and coerced
in the set_option() method.

""" Callable object, which returns pathnames relative to SCons current
working directory.
It seems like `SCons.Node.FS.Base.get_path()` returns absolute paths
for nodes that are outside of current working directory (`env.fs.getcwd()`).
Here, we often have `SConscript`, `POT` and `PO` files within `po/`
directory and source files (e.g. `*.c`) outside of it. When generating `POT`
template file, references to source files are written to `POT` template, so
a translator may later quickly jump to appropriate source file and line from
its `PO` editor (e.g. `poedit`). Relative paths in `PO` file are usually
interpreted by `PO` editor as paths relative to the place, where `PO` file
lives. The absolute paths would make resultant `POT` file nonportable, as
the references would be correct only on the machine, where `POT` file was
recently re-created. For such reason, we need a function, which always
returns relative paths. This is the purpose of `RPaths` callable object.
The `__call__` method returns paths relative to current working directory, but
we assume, that *xgettext(1)* is run from the directory, where target file is
going to be created.
Note, that this may not work for files distributed over several hosts or
across different drives on windows. We assume here, that single local
filesystem holds both source files and target `POT` templates.
Intended use of `RPaths` - in `xgettext.py`::
def generate(env):
from GettextCommon import RPaths
...
sources = '$( ${_concat( "", SOURCES, "", __env__, XgettextRPaths, TARGET, SOURCES)} $)'
env.Append(
...
XGETTEXTCOM = 'XGETTEXT ... ' + sources,
...

# current working directory. The pathname remains relative also for entries
# that are outside of current working directory (node, that
# SCons.Node.FS.File and siblings return absolute path in such case). For
# simplicity we compute path relative to current working directory, this
# seems be enough for our purposes (don't need TARGET variable and

This is the flow of the compiler detection logic:
External to MSCommon:
The Tool init modules, in their exists() routines, call -> msvc_exists(env)
At the moment, those modules are:
SCons/Tool/midl.py
SCons/Tool/mslib.py
SCons/Tool/mslink.py
SCons/Tool/msvc.py
SCons/Tool/msvs.py
env may contain a version request in MSVC_VERSION, but this is not used
in the detection that follows from msvc_exists(), only in the later
batch that starts with a call to msvc_setup_env().
Internal to MSCommon/vc.py:
+ MSCommon/vc.py:msvc_exists:
| vcs = cached_get_installed_vcs(env)
| returns True if vcs > 0
|
+-> MSCommon/vc.py:cached_get_installed_vcs:
| checks global if we've run previously, if so return it
| populate the global from -> get_installed_vcs(env)
|
+-> MSCommon/vc.py:get_installed_vcs:
| loop through "known" versions of msvc, granularity is maj.min
| check for product dir -> find_vc_pdir(env, ver)
|
+-> MSCommon/vc.py:find_vc_pdir:
| From the msvc-version to pdir mapping dict, get reg key base and value
| If value is none -> find_vc_pdir_vswhere(ver, env)
|
+-> MSCommon/vc.py:find_vc_pdir_vswhere:
| From the vc-version to VS-version mapping table get string
| Figure out where vswhere is -> msvc_find_vswhere()
| Use subprocess to call vswhere, return first line of match
/
| else get product directory from registry (<= 14.0)
/
| if we found one -> _check_cl_exists_in_vc_dir(env, pdir, ver)
|
+-> MSCommon/vc.py:_check_cl_exists_in_vc_dir:
| Figure out host/target pair
| if version > 14.0 get specific version by looking in
| pdir + Auxiliary/Build/Microsoft/VCToolsVersion/default.txt
| look for pdir + Tools/MSVC/{specver}/bin/host/target/cl.exe
| if 14.0 or less, "do older stuff"
All of this just got us a yes-no answer on whether /some/ msvc version
exists, but does populate __INSTALLED_VCS_RUN with all of the top-level
versions as noted for get_installed_vcs
Externally:
Once a module's exists() has been called (or, in the case of
clang/clangxx, after the compiler has been detected by other means -
those still expect the rest of the msvc chain but not cl.exe)
the module's generate() function calls -> msvc_setup_env_once(env)
Internally:
+ MSCommon/vc.py:msvc_setup_env_once:
| checks for environment flag MSVC_SETUP_RUN
| if not, -> msvc_setup_env(env) and set flag
|
+-+ MSCommon/vc.py:msvc_setup_env:
| set ver from -> get_default_version(env)
|
+-+ MSCommon/vc.py:get_default_version:
| if no version specified in env.MSVC_VERSION:
| return first entry from -> cached_get_installed_vcs(env)
| else return requested version
/
| get script from MSVC_USE_SCRIPT if set to a filename
| -> script_env(script)
|
+-+ MSCommon/vc.py:script_env:
| return (possibly cached) script variables matching script arg
/
| else -> msvc_find_valid_batch_script(env, version)
|
+-+ MSCommon/vc.py:msvc_find_valid_batch_script:
| Build a list of plausible target values, and loop through
| look for host + target -> find_batch_file(env, ver, host, target)
|
+-+ MSCommon/vc.py:find_batch_file:
| call -> find_vc_pdir (see above)
| use the return to construct a version-biased batfile path, check
/
| if not found, try sdk scripts (unknown if this is still useful)
Problems:
- For VS >= 2017, VS and VS are not 1:1, there can be many VC for one VS
- For vswhere-ready versions, detection does not proceed beyond the
product level ("2019") into individual "features" (individual msvc)
- As documented for MSVC_VERSION, compilers can only be requested if versions
are from the set in _VCVER, so 14.1 but not 14.16 or 14.16.27023
- Information found in the first pass (msvs_exists) isn't really
available anywhere except the cached version list, since we just
return true/false.
- Since msvc_exists chain of calls does not look at version, we
can proceed to compiler setup if *any* msvc was found, even if the
one requested wasn't found.

SCons tool selection.

a construction environment as appropriate for a given tool (or tool
chain).
Note that because this subsystem just *selects* a callable that can
modify a construction environment, it's possible for people to define
their own "tool specification" in an arbitrary callable function. No

Implements the ability for SCons to emit a compilation database for the MongoDB project. See
http://clang.llvm.org/docs/JSONCompilationDatabase.html for details on what a compilation
database is, and why you might want one. The only user visible entry point here is
'env.CompilationDatabase'. This method takes an optional 'target' to name the file that
should hold the compilation database, otherwise, the file defaults to compile_commands.json,
