[Question] Problem with mingw gcc on WIndows11

[anzhi0708]

I'm using GCC in Windows Terminal (PowerShell), but it seems that SCons detects the current environment as CMD, which prevents compilation.

PS C:\Users\me\dev\cpp\helloworld> (get-command gcc).Source

C:\Users\me\scoop\apps\gcc\current\bin\gcc.exe

PS C:\Users\me\dev\cpp\helloworld> gcc -dumpmachine

x86_64-w64-mingw32

PS C:\Users\me\dev\cpp\helloworld> gcc -v

Using built-in specs.

PS C:\Users\me\dev\cpp\helloworld> cat .\SConstruct

env = Environment()
env.Replace(CXX=r"C:\Users\me\scoop\apps\gcc\current\bin\g++.exe")
env.Program("main.exe", Glob("#/src/*.cpp"))

Call the mingw tool to get it set up. It's not sufficient to just change the name of the compiler, since if the msvc environment is detected, its construction variables (settings) are configured as the default (as you've seen). I believe this should work:

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