[gdal-dev] can't import osgeo or gdal in python

[Jeff Hamann]

Hi list, 

First, let me say, I'm *not* a python person, so please be gentle with your assumptions.

I built gdal-1.7.2 with the following configure options:


$ ./configure \
 CC="gcc -arch i386" \
 CXX="g++ -arch i386" \
OBJC="gcc -arch i386" \
 F77="gfortran -arch i386" \
 FC="gfortran -arch i386" \
  --with-pg=/usr/local/pgsql/bin/pg_config \
  --with-macosx-framework=NO \
  --without-sqlite3  \
  --with-python

configure: WARNING: unrecognized options: --with-macosx-framework

GDAL is now configured for i386-apple-darwin10.4.0

Jeff-Hamanns-MacBook-Pro:gdal-1.7.2 hamannj$ 


okay, a little odd (-with-macosx-framework, --with-swig) when ./configure --help contains:

  --with-macosx-framework         Build and install GDAL as a Mac OS X Framework
  --with-perl           Enable perl bindings
  --with-php            Enable php bindings
  --with-ruby           Enable Ruby bindings
  --with-python       Enable python bindings

but, it builds and installs just fine. I can also build things that depend on gdal (i.e. wktraster). 

When I try to "run" (again newbie talking here, so be patient), a python script and import gdal:

Jeff-Hamanns-MacBook-Pro:gdal-1.7.2 hamannj$ python

I can't seem to get any traction, but can somebody provide an answer as to why gdal isn't loading?

Please?

Respectfully,
Jeff.
