Python 2.6.5 build fails on MSYS with the following messages

I don't think MSYS (or mingw32) is supported at all.
I'm even surprised that the build went so far.

I thought Python ran everywhere. That's what the documentation says.

Python does *run* on Windows (when compiled with Visual Studio or gcc via Cygwin), it just might not be setup to build with the MSYS compiler.

Martin (Ellison): What people are trying to say is that likely, nobody will be working on this, and likely so for the next few years. So unless you volunteer to provide a patch, I recommend to close the issue as "won't fix". Unassigning myself.

I fixed all build problems on the current MinGW32. python.exe builds ok, but build fails since python.exe can't find some modules after this. Not sure why.

hum, your patch actually works on MSYS !

ok.. so I am pretty much having the very some issue.


Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: Py_Initialize: unable to load the file system codec
LookupError: no codec search functions registered: can't find encoding

If I am reading this right, then in the below part of the patch, slave_name does not get set before it is used if __MINGW32__ is not defined. this can be fixed by moving the "#endif" up to the line before
    slave_name = ptsname(master_fd); /* get name of slave */

No activity since 2012, I close the issue.
