Hi! For building python with mingw you need some patches) You can find them on https://github.com/niXman/mingw-builds/tree/master/patches/Python-2.7.3. 2012/11/5 Václav Šmilauer > > Hi, Vaclav! > Can you try to build python module with this > toolchain

Re: [Mingw-w64-public] Error building python extension (DLL load failed: invalid access to memory location)

I settled for the "fix" of using mingw.org gcc 4.6.2 32bit but don't understand why it works since the 4.6.2 .pyd's still have deps on msvcr90.dll and msvcrt.dll...need to try again with a custom spec to force everything to msvcr90.dll and try with http://sourceforge.net/projects/mingwbuilds/fi

Hi, Vaclav! Can you try to build python module with this toolchain ? There are Python-2.7.3 in subdirectory "opt" compiled with this toolchain. Hi Alex, thanks for your suggestion, I would like to first try with

Hi, Vaclav! Can you try to build python module with this toolchain? There are Python-2.7.3 in subdirectory "opt" compiled with this toolchain.

Hi everybody, I am fairly new to MinGW64 (and to windows) and this is my first post to the list. I would like to thank to the authors of and contributors to mingw64 in the first place. I am trying to build compiled python modules, which use some compiled libraries (boost, in particular). The
