SCons can't pick the compiler (MinGW)

I have a simple SConstruct file with the following code

path = ['C:\\MinGW\\bin']
env = Environment(ENV = {'PATH' : path})

Program(target = 'myprogram', source = ['main.cpp'])

running 'scons' on cmd gives the following error message:

cl /Fomain.obj /c main.cpp /TP /nologo
'cl' is not recognized as an internal or external command,
operable program or batch file.
scons: *** [main.obj] Error 1
scons: building terminated because of errors.

It looks like SCons does not pick my compiler (MinGW). What am I doing wrong? I'm on Windows 7 64bit.

Solution

  • After setting tools variable in environment you should use env.Program('...') instead of Program('...'). Below is my working SConstruct for mingw:

    path = ['C:\\Dev\\MinGW\\x64-4.9.2-posix-seh-rt_v3-rev1\\mingw64\\bin']
temp = 'C:\\Temp'

env = Environment(ENV={'PATH': path, 'TEMP': temp}, 
                  tools=['mingw'])

env.Program('solver-tikhonov.cpp')
