Re: [Boost-users] Boost-users Digest, Vol 3819, Issue 2
Thanks Nat. I'm wondering if there is a powerpc built binary including context to download?

I didn't find this page but as I understand it helps to install python libs (extensions) with mingw. What I try to do is build python from src to get an appropriate static library. I can link it with my Qt toolchain (Mingw 4.6.3) and it compiles without error, but it fails to run. I double check it. All of my libs and tools are 32-bit. Thank you very much for your help.

This is educational for me; to minimize pain, I settled on visual studio + intel compiler long ago whenever I am coerced into windows development.
You mentioned that did some surfing; did you encounter this page <http://www.secker.nl/2012/03/08/setup-python-2-7-2-and-mingw-on-windows-xp/>? Apparently, mingw should be able to link against the standard, visual studio compiled python lib. Which would be a blessing for you if it works... Are you trying to build 32-bit binaries linked against 64-bit python libs by any chance?
If you don't get any joy, I'll try setting up an official python binaries + mingw environment on my windwoes system at home after work today or tomorrow. Are you strictly targeting 2.7?

Hi Erik,
Thanks for the response. Yes I'm using makefile but I think the problem is different. Here is the gcc command that fails: gcc -c -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o Python/asdl.o Python/asdl.c It has a -I./Include argument.
So, I surf the Internet (a lot) and I found that at initial there were no autotool support for installing python from source. Later I found a Python 3.4 page were I could download an src setup for mingw installation. Unfortunatly that doesn't work either. So I reinstalled my Python and somehow I could link the library to my project. (I don't know how this possible, but the latest version of 2.7 works with my project. Blind luck I guess.) I could use PyRun_SimpleString but the PyRun_SimpleFileEx call crashes for some reason. Than I tried boost::python and it crashes aswell at the first object result = eval("5/2"); call. (I didn't forget to call Py_Initialize();).
Any suggestions?
Thanks, Mikl?s

Hi Mikl?s,
Are you using a makefile? If so, it looks like you need to add -I/cygdrive/e/INSTALL/python_src/Python-2.7.6/Include to the Makefile's CFLAGS or CC variable, or somehow ensure that -I/cygdrive/e/INSTALL/python_src/Python-2.7.6/Include is passed to the compiler in any case.
Regards, Erik

Hi!
Any updates on this? I get the following error:
/cygdrive/e/INSTALL/python_src/Python-2.7.6 $ mingw32-make process_begin: CreateProcess(NULL, /usr/bin/mkdir -p Include, ...) failed. make (e=2): The system cannot find the file specified. mingw32-make: *** [Include/graminit.h] Error 2
but the corresponding file is there:
/cygdrive/e/INSTALL/python_src/Python-2.7.6 $ ls Include/g*Include/genobject.h Include/graminit.h Include/grammar.h
What am I missing? Any thoughts?
Thanks, Mikl?s

Hi All,
I want to embed python in my c++ code using boost.python library. As far as I understand I need python headers and libs. So my python27.lib is "incompatible". I want to compile it from code but I failed with mingw32. Could you give me some advice, or links to achieve my goal? I'm using gcc4.6.3 and qt 4.8.2 and boost 1.49 on windows 7. Thanks, Mikl?s
