visual studio - How to tell scons to use MinGW instead of MSVC

Question

I'm trying to build the C++ port of zxing on Windows, but scons fails with:

cl : Command line error D8021 : invalid numeric argument '/Wextra'

I have both VS2010 and MinGW installed, and scons tries to use the MSVC compiler, even though the SConscript file assumes gcc and use gcc-specific parameters, which causes the error.

How can I tell scons to use MinGW instead?

Answer 1

Scons uses MSVC compiler by default on windows. To set mignw compiler use tools parameter while creating Environment object.

env = Environment(tools = ['mingw'])

And then use env.Program() instead of Program().
