[gdal-dev] gdal and python problems

[Andreas Neumann]

Hi,

I was compiling gdal with python support from svn-trunk and ran into the
same problem as described at

http://www.nabble.com/Problem-with-gdal_polygonize.py-td19839558.html

When I start a python script I get the following error message:

------------------
gdal_merge.py -o orthofoto_2008.tif -init 255,255,255 -v -co
"COMPRESS=PACKBITS" -of GTiff OF_10cm/69*.tif
Traceback (most recent call last):
  File "/usr/local/bin/gdal_merge.py", line 31, in <module>
    import gdal
  File "/usr/local/lib/python2.5/site-packages/gdal.py", line 2, in <module>
    from osgeo.gdal import deprecation_warn
  File "/usr/local/lib/python2.5/site-packages/osgeo/gdal.py", line 7, in
<module>
    import _gdal
ImportError: /usr/local/lib/python2.5/site-packages/osgeo/_gdal.so:
undefined symbol: GDALPolygonize
------------------

My system is Ubuntu 8.10 (Intrepid Ibex). I used the following configure
options:

./configure --with-perl --with-python --with-xerces --with-sqlite
--with-pg=/usr/local/pgsql/bin/pg_config --enable-bigtiff
--with-odbc=/usr/lib --with-libtiff=internal
--with-grass=/usr/local/grass-6.3.0

Here is the output of configure:

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

Maybe I am missing some python packages. On Ubuntu 8.10 there are a
gazillion of python packages. I made sure I installed the swig and sip,
incl. the dev packages.

Any idea what went wrong with my install or which package I am missing?

Thanks,
Andreas
