gcc compilation error from python
Solution 1
So, after a while, I stumbled across a post that so far has worked for me.
http://www.develer.com/oss/GccWinBinaries
This site provides an unofficial MinGW GCC binary (not supported/endorsed by MinGW) that is meant to integrate perfectly with Python, down to the automatic updating of paths. I installed it and bam, pip install cython
just started working.
Hope this helps more of you out there with this gcc problem.
Solution 2
I've just answered the same question: why does dllwrap give this error within pip?
_foo.exp: file not recognized: File format not recognized
Short answer: check your PATH. MinGW\bin needs to be near the start of it.
Long answer: see python pip package install fails , dllwrap error after 'fixing': "unable to find vcvarsall.bat"

I know that there are lots of threads on gcc, particularly "command gcc failed with exit status 1", and I've looked at them all and still have not been able to fix this. I only would use gcc or mingw32 for python-related tasks, such as using Cython or other packages that might involve compilation. However, it never seems to work.
I have a PC with Windows 7 Home edition. I've installed cygwin on it with mingw32, and I also have Visual Studio 11 Beta installed, and I'm happy to uninstall/reinstall anything to get this to work.
Cython compilations always fail with
error: command 'gcc' failed with exit status 1
But even trying to install many python packages using pip fails with a similar error. For example, I'm trying to install a package called "xhtml2pdf." After running "pip install xhtml2pdf" in the command prompt, I get the following error:
copying src\reportlab\lib\hyphen.mashed -> build\lib.win32-2.7\reportlab\lib running build_ext building '_rl_accel' extension C:\mingw\bin\gcc.exe -mno-cygwin -mdll -O -Wall -IC:\Python27\include -IC:\Pytho n27\PC -c "C:\Users\JJ\Documents\Coding Fun\build\reportlab\src\rl_addons\rl_acc el\_rl_accel.c" -o "c:\users\jj\documents\coding fun\build\reportlab\src\rl_addo ns\rl_accel\_rl_accel.o" cc1.exe: error: unrecognized command line option '-mno-cygwin' error: command 'gcc' failed with exit status 1
Running the same command from cygwin yields a different error:

I'm very new to compilation in general, having worked only with interpreted languages, so I've been frustratingly unable to figure out how to fix this myself. Any help would be appreciated in getting this package installed.
EDIT: I have previously followed advice like trying to remove all references to "-mno-cygwin" in distutils and creating a distutils.cfg file, but to no avail.
UPDATE: After reinstalling cygwin and also downgrading my installations of gcc and g++ to v3, I get another, but different, error:

gaborous about 9 yearsGccWinBinaries DOES support 64-bit Windows, just not 64-bit Python. But with a 32-bit Python it works flawlessly on my Windows 7 64-bit machine. It won't however compile Cython extensions.
