Cannot get Cython to find the MinGW gcc compiler even after editing PATH, making a file in distutils, removing all instances of -mno-cygwin
Question: I am trying to get cython to realize I have a c compiler in MinGW 32-bit and
I've tried everything I can find on the web but it's still not working. I am
running Windows 7 Professional 64-bit. Here is what I have tried:

(1) I have Python 2.7 and I just installed MinGW with options gcc and g++ and
some other options

(2) I edited the PATH environmental variable so it includes

    
    
    C:\MinGW\bin;C:\MinGW\MSYS\1.0\local\bin;C:\MinGW\MSYS\1.0\bin
    

(3) I told Python to use MinGW as the default compiler by creating a file
named

C:\Python27\Lib\distutils\distutils.cfg, containing

    
    
    [build]
    compiler = mingw32
    

(I do have MinGW32 by the way)

(4) I removed all instances of -mno-cygwin from the file
C:\Python27\Lib\distutils\cygwincompiler.py

(5) I have a file called setup.py and a module called tryingcython.pyx that is
written in python. My setup.py says from distutils.core import setup from
distutils.extension import Extension from Cython.Distutils import build_ext

    
    
    setup(
        cmdclass = {'build_ext':build_ext},
        ext_modules=[Extension("tryingcython",["tryingcython.pyx"])]
    )
    

So then I open Command Prompt and get into the directory that contains
setup.py and tryingcython.pyx, and I type python setup.py build_ext --inplace
--compiler=mingw32

Then it tells me:

    
    
    running build_ext
    skipping 'tryingcython.c' Cython extension (up-to-date)
    building 'tryingcython.c' extension
    gcc -mdll -O -Wall -IC:\Python27\include -IC:\Python27\PC -c tryingcython.c -o build\
    temp.win32-2.7\Release\tryingcython.o
    error: command 'gcc' failed: No such file or directory
    

So I guess Cython can't tell that I have gcc and it can't find it or what,
even though I've tried about every single piece of advice I can find online
for making it realize that I have MinGW which has gcc included. Any
help/additional ideas on how I can get cython to actually work would be much
appreciated.


Answer: You are using exactly the same operational system and versions than me.

Try to cal `gcc` using:

    
    
    SET input=intput.c
    SET output=output.pyd
    gcc -shared  -IC:\Python27\include -LC:\Python27\libs -O2 -o %output% %input% -lpython27
    

Usually I put this call in a `cythongcc.bat` file, in a directory recognized
by the `PATH` environment variable as:

    
    
    gcc -shared  -IC:\Python27\include -LC:\Python27\libs -O3 -mtune=native -o %1.pyd %2.c -lpython27
    

So that I can , from where my cython `.pyx` files are, just do:

    
    
    cython input.pyx
    cythongcc input input
    

To get the compiled `.pyd` working!
