Hi Erik,
Unfortunatly Visual Studio is not an option for me.
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.
Regards,
Mikl?s

I think we can answer affirmatively as to whether it's supported:
https://github.com/boostorg/context/tree/master/src/asmThis directory appears to contain PowerPC implementations for elf,
macho and xcoff, 32 and 64 bits, and even "universal" for macho.
But I do not know how you would cross-compile (cross-assemble?)
that
on an x86 machine, sorry.

This list:
http://www.boost.org/doc/libs/includes for each library the Boost release in which it was first
introduced. According to that, Locale was introduced in 1.48.

But you do want to build a Python lib (extension). Boost::python uses the
cpython API in the same way as any other python extension and it has the
same requirements. Just as you should be able to build pyqt with mingw
linking against the official Python binaries, you should be able to build a
boost::python extension with mingw linking against the official Python
binaries.
However, that is all hearsay. It *should* work, according to *stuff I read
online*. I will try it at home tonight to confirm/deny this putative
workingness.
Glad to be of help.
