[Scons-dev] Windows Path

[alexandre.feblot at gmail.com]

Hi,

Creation of a temporary dir containing symlinks to tools which have been found, and adding this dir in the SCons PATH?
On windows, this can be achieved with junction points (this is pretty much what we do to force using the 64 bit linker during a 32 bit compilation due to the size of our libs/executables in debug mode).

Regards

Some tools just put the whole path to the tool executable in as the value of, say, $CC.  But that of course makes the generated compile lines look ugly.
