I'm trying to build latest SVN trunk with Python bindings on Mac OS X + GCC 4.0.1. Everything (GDAL + utilities) builds with success, but the Python bindings that report undefined references in libcurl. Here are all steps I've taken:
- Compilation goes to swig and stops with errors
(cd swig; make build)
for dir in python ; do (cd $dir; make build) || exit; done
python setup.py build
running build
running build_py
creating build
creating build/lib.macosx-10.3-fat-2.5
copying gdal.py -> build/lib.macosx-10.3-fat-2.5
copying ogr.py -> build/lib.macosx-10.3-fat-2.5
copying osr.py -> build/lib.macosx-10.3-fat-2.5
copying gdalconst.py -> build/lib.macosx-10.3-fat-2.5
creating build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/__init__.py -> build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/gdal.py -> build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/gdal_array.py -> build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/gdalconst.py -> build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/gdalnumeric.py -> build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/ogr.py -> build/lib.macosx-10.3-fat-2.5/osgeo
copying osgeo/osr.py -> build/lib.macosx-10.3-fat-2.5/osgeo

- libgdal and ogrinfo can find and link to libcurl
~/dev/gdal/_svn/trunk/gdal $ otool -L libgdal.dylib|grep curl
/usr/lib/libcurl.4.dylib (compatibility version 5.0.0, current version 5.0.0)
~/dev/gdal/_svn/trunk/gdal $ otool -L ./apps/ogrinfo|grep curl
/usr/lib/libcurl.4.dylib (compatibility version 5.0.0, current version 5.0.0)
I don't understand it what's the distinction between libcurl requirements for GDAL + utilities and Python bindings. If the former can find necessary definitions, why Python bindings can not? Do they need anything extra?
