[Scons-users] set Windows environment for 32 or 64 bit x86 builds

[Rob Boehne]

All,

I've inherited a complicated cross-platform build in SCons, involving swig, C++, C# and Java.   On all platforms but windows, it uses a command-line argument to the compiler to generate code for 64-bit or 32-bit.  Under windows however, it runs the "vcvarsall.bat" with the appropriate argument, and then goes through some machinations to get the variables it sets into the scons environment.

Is this even a little bit necessary?  What is the canonical method for specifying 32 or 64-bit code generation?

Thanks
