Subversion Python bindings breaking on SWIG_TypeQuery

["Fancher, Bruce" <bf...@hfmus.com>]

Hi.  I'm still having trouble with the python bindings, and SWIG_TypeQuery in particular.  From googling I see that I'm not the only one who's had similar problems, but I couldn't find a solution to the problem I'm having.

In a nutshell, when I try to test the Subversion python bindings, I get this:

[root@meatwad subversion-1.1.1]# tools/examples/svnlook.py
Traceback (most recent call last):
  File "tools/examples/svnlook.py", line 23, in ?
    from svn import core, fs, delta, repos
  File "/usr/local/lib/svn-python/svn/core.py", line 21, in ?
    from libsvn.core import *
  File "/usr/local/lib/svn-python/libsvn/core.py", line 5, in ?
    import _core
ImportError: /usr/local/lib/libsvn_swig_py-1.so.0: undefined symbol: SWIG_TypeQuery

I find SWIG_Python_TypeQuery, not SWIG_TypeQuery:

[root@meatwad subversion-1.1.1]# ldd /usr/local/lib/libsvn_swig_py-1.so.0 | grep libswigpy
        libswigpy.so.0 => /usr/local/lib/libswigpy.so.0 (0xb75f7000)

[root@meatwad subversion-1.1.1]# nm -A /usr/local/lib/libswigpy.so | grep -i SWIG_TypeQuery

[root@meatwad bruce]# nm -A /usr/local/lib/libswigpy.so | grep -i SWIG_Python_TypeQuery
/usr/local/lib/libswigpy.so:000012dc T SWIG_Python_TypeQuery

Although I see a few statements like #define SWIG_TypeQuery SWIG_Python_TypeQuery in both the subversion and swig source trees.  So, where is SWIG_TypeQuery supposed to be coming from?  Is SWIG not building correctly on my system or is the problem elsewhere?

Any help would be appreciated.

Thanks,

Bruce Fancher

It's bogus.  There is no SWIG_TypeQuery.  There is definitely something 
wrong with your build.

The latter one is what's supposed to be there.

I imagine that something isn't building correctly on your system.  I've 
compiled both the 1.1.1 and the trunk/ bindings, and they compile and 
work just fine on my box.

Can you provide more information about the machine your trying to compile 
on?  Which OS?  Which version of SWIG?  IIRC, I saw another post where 
you had tried a couple of different versions.  Perhaps, there is some 
left over crud for the previous SWIG version that's causing a failure?

FWIW, I'm running SuSE 9.1, which has SWIG 1.3.21 and Python 2.3.3.  I've 
also got this running on SuSE 9.2, which has SWIG 1.3.21 and Python 
2.3.4.
