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.
