[Scons-users] Re-2: Re-2: GCC not found Error SCONS 3.1.2

[Paul Rötzer]

Hi, 

What I found out so far with Scons 3.1.2: 
- In mingw.py generate(env) the variable mingw_paths contains 'c:\\MinGW\\bin'
- C:\MinGW\bin contains "mingw32-gcc.exe" but not "mingw32-make.exe"
- SCons.Tool.find_program_path(env, key_program, default_paths=mingw_paths) returns None

- if I change the key_program variabel in mingw.py to key_program = 'gcc' it works. 

Hopefully this helps 

Paul

There's now a mingw platform module - don't know

3.0.0, would have to do some prospecting.  It defines

if sys.platform == 'win32':

        r'C:\msys64',
        r'C:\msys'
