-Tool-specific initialization for the Digital Mars D compiler.
-(http://digitalmars.com/d)
-
-Coded by Andy Friesen (andy@ikagames.com)
-15 November 2003
-
-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)
