My environment:

Windows7 32 bit
python 2.6 and python 3.2 installed (C.\Pythonx.x\...)

by the way, when I write the command "python" at the command prompt,
then python26 starts (not python32)


What I did:

download latest build and windows dependencies with SVN and placed in
C.\BlenderSVN
(then I have two folders in C.\BlenderSVN: "blender" and "lib")

I run Cmake 2.8.2 gui and set:

- source code location: "C:/BlenderSVN/blender"
- where to build the binaries: "C:/BlenderSVN/build"

then
1) click configure once
2) specify the generator for the project as "MinGW Makefiles" (Use default
native compilers)

I get the following configure info:

The C compiler identification is GNU

The CXX compiler identification is GNU

Blender Skipping: (bf_collada;bf_imbuf_openexr;extern_redcode)

Could NOT find Subversion (missing: Subversion_SVN_EXECUTABLE)

Configuring done

3) tick the box WITH_PYTHON_MODULE and unselect the box WITH_PYTHON_INSTALL
(WITH_PLAYER is already unselected)

4) click for the second time configure

This time I get these messages:

Blender Skipping: (bf_collada;bf_imbuf_openexr;extern_redcode)

Could NOT find Subversion (missing: Subversion_SVN_EXECUTABLE)

Configuring done



5) click generate



At this point I close Cmake gui, open the windows shell and run the
following commands:



cd C:\BlenderSVN\build

mingw32-make



(the compilation ends like:



[100%] Building C object
source/creator/CMakeFiles/blender.dir/buildinfo.c.obj
Linking CXX shared library ..\..\bin\bpy.pyd

unrecognized

)


mingw32-make *install*

**

After the installation, still in the shell I write the following commands:



copy bin\bpy.pyd C:\Python32\Lib\site-packages\
xcopy /E bin\2.56 C:\Python32\



(last command actually copies only the sub-folders of the 2.56 folder so
that I have three different folders - config, datafiles, scripts - in
C:\Python32   -----> however I tried also copying the whole 2.56 folder..)


....and still get the same error message:

ImportError: DLL load failed: %1 non è un'applicazione di Win32 valida.
