move v8 src to google dir moving v8 source into main extension move google upstream source dir into v8 ext dir include v8 library in generated bundle prep for 0.4.7 roll the upstream build into the main extension build Documentation was confusing the gem packager. simplify build instructions with bundled v8. Only install scons and build v8 if it has not been built already. Missing CVS.py from the scons library due to ignore patterns. Don't need libv8 anymore, only python 2.5 which is required to build it.

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)
