With the help of SCons.Environment.ParseFlags, split user-supplied
CUSTOM_LDFLAGS into appropriate option lists: LIBPATH, LIBS, etc.
Known non-linker options (like -Dx -I.) will be reported and ignored,
unrecognized options will be appended to LINKFLAGS.
Passing CUSTOM_LDFLAGS='-Wl,-rpath=$ORIGIN' to ./configure is
unnecessarily difficult and error-prone. The option needs to be
protected from SCons variable substitution by doubling the '$',
and also from shell parameter expansion with a backslash.
Such fortified value then cannot be used directly in contexts
where either expansion does not happen.
This commit makes that protection optional by injecting variable
named ORIGIN, that resolves to '$ORIGIN', into both the SCons
construction Environment and the process environment, so whenever
'$ORIGIN' undergoes variable substitution, it is replaced by the
original string.
It shouldn't be a conftest. First, it doesn't act like one. Second,
calling it as conf.rollback_option from within another conftest before
calling context.Result confuses scons, it doesn't expect conftests to be
nested and reports "error: no result" for the outer one as soon as the
inner is called.
Forgot that with `TryAction`, configure commands and their outputs were
being logged in `config.log`, and the previous commit failed to retain
this ability.
New function `config_command` mimics the logging, with the modification
that output lines are prefixed with `->` so they stand out a bit more.
Closes#3918
Replace all previous uses of `call` and `TryAction` with a new function
`silent_command`, which invokes `subprocess.Popen` and returns both exit
status and command output.
* geobuf.input - initial implementation (WIP)
* geobuf.input - fix reading MultiPolygon's
* geobuf.input - don't store invalid bounding boxes in r-tree.
* Use `protozero` lib to read `geobuf` (Initial implementation, not complete!)
* geobuf.input - poring to `protozero`. (TODO: add support for `GeometryCollection`)
* add initial support for `GeometryCollection` + cleanup namespaces
* remove stderr + cleanup + update copyright
* fix GeometryCollection and MultiLineString decoding + add support for standalone Feature and Geometry
* don't use `reserve` as undelying data format doesn't allow for efficient `distance` implementation.
* add geobuf unit test + update test data
* update data
- this was intended to be used by python-mapnik
- but it is not currently, so let's clean it up
- todo: get actual ICU_DATA,PROJ_LIB,GDAL_DATA values from those depependent libs
