Tool-specific initialization for the Digital Mars D compiler.

|
|
There are a number of problems with this script at this point in time.
|
|
The one that irritates me the most is the Windows linker setup. The D
|
|
linker doesn't have a way to add lib paths on the commandline, as far
|
|
as I can see. You have to specify paths relative to the SConscript or
|
|
use absolute paths. To hack around it, add '#/blah'. This will link
|
|
blah.lib from the directory where SConstruct resides.
|
|
|
|
Compiler variables:
|
|
DC - The name of the D compiler to use. Defaults to dmd or gdmd,
|
|
whichever is found.
|
|
DPATH - List of paths to search for import modules.
|
|
DVERSIONS - List of version tags to enable when compiling.
|
|
DDEBUG - List of debug tags to enable when compiling.
|
|
|
|
Linker related variables:
|
|
LIBS - List of library files to link in.
|
|
DLINK - Name of the linker to use. Defaults to dmd or gdmd.
|
|
DLINKFLAGS - List of linker flags.
|
|
|
|
Lib tool variables:
|
|
DLIB - Name of the lib tool to use. Defaults to lib.
|
|
DLIBFLAGS - List of flags to pass to the lib tool.
|
|
LIBS - Same as for the linker. (libraries to pull into the .lib)
