[gdal-dev] mod_python issue with libtiff

[Andreas Neumann]

Hi,

I recently upgraded my gdal version to the recent SVN version. The
command-line tools work fine, but my python scripts inside Apache
mod_python fail with the following error:

--------------------------

I set the libtiff to "internal" in the configure options before the compile.

I don't understand why the mod_python scripts link to libtiff 3.x. Why are
the commandline tools (gdal-info, gdal-translate, gdal_merge.py, etc.)
working fine, but the scripts inside mod_python do not.

Both are using python2.6.

Thank you very much for any pointers or hints on what may be wrong in my
configuration.

Andreas
