Compiling python bindings (VS2012, Windows 7)

["Cooke, Mark" <ma...@siemens.com>]

Dear list,

I thought I had subversion compiled OK, all the tests appear to be passing, but when I went looking for the python bindings they were missing.  Looking at the VS2012 solution file, the __SWIG_PYTHON__ project seems to be empty and does nothing when rebuilt.

So I have re-built the following [Libraries > Swig] projects:
- libsvn_swig_py
- swig_python_core
- swig_python_client
- swig_python_delta
- swig_python_diff
- swig_python_fs
- swig_python_ra
- swig_python_repos
- swig_python_wc

All appear to build OK (although with plenty of warnings) and I end up with a collection of pyd files in D:\svn\src\Release\subversion\bindings\swig\python
...plus
D:\svn\src\Release\subversion\bindings\swig\python\libsvn_swig_py\libsvn_swig_py-1.dll

I copied the files following the instructions here:

[1] http://www.lejordet.com/2009/03/compiling-subversion-python-bindings-on-windows/

...creating `svn` and `libsvn` folders, then copied those to my python install [Lib\site-packages].

However, I still get the dreaded "ImportError: DLL load failed: The specified module could not be found."

I tried copying the three APR DLLs to libsvn in case but that does not seem to have helped.

Should I compile subversion with the "--disable-shared" option?

Or, there is a comment at [1] concerning the _USE_32BIT_TIME_T preprocessor definition for APR and Swig, is this still an issue for subversion 1.8.10 builds?

Thanks for any pointers...

On the buildbot I use two scripts for running the python tests:

For trunk/1.9 I use:
################
python win-tests.py -r -f fsfs --swig=python "%TESTDIR%\tests"
(The actual script is in win-tests.py)

For older versions:
################
    IF EXIST "%TESTDIR%\swig" rmdir /s /q "%TESTDIR%\swig"
    mkdir "%TESTDIR%\swig\py-release\libsvn"
    mkdir "%TESTDIR%\swig\py-release\svn"

    xcopy "release\subversion\bindings\swig\python\*.pyd"
"%TESTDIR%\swig\py-release\libsvn\*.pyd" > nul:
    xcopy "release\subversion\bindings\swig\python\libsvn_swig_py\*.dll"
"%TESTDIR%\swig\py-release\libsvn\*.dll" > nul:
    xcopy "subversion\bindings\swig\python\*.py"
"%TESTDIR%\swig\py-release\libsvn\*.py" > nul:
    xcopy "subversion\bindings\swig\python\svn\*.py"
"%TESTDIR%\swig\py-release\svn\*.py" > nul:

    SET PYTHONPATH=%TESTDIR%\swig\py-release

    python subversion\bindings\swig\python\tests\run_all.py



I'm not sure if this really follows recommended practice, but it does allow
me to run the python tests on Windows as a non admin.
