[1.7] ctypes / geos / python / django
I asked a similar post on the python mailing list as i don't know where people can help me on that subjet. So, for my fellows readers, now that i have geos compiled and fully functionnal, my next step is to validate the Django ctypes bindings, and we have there some tests to do that. Here come problems. With my python-2.6.4 hand made with some patches stolen from cygwin port (specially the ctypes one, and some arrangements (load cygpython26.Dll instdead of libpython26.dll for example), i can compile and use a c or a c++ helloworld library without problems and unittest for ctypes do not fail. However, using it in my real world UseCase (django + geos), make me think that there is a problem with ctypes. $ cat geos.py from django.contrib.gis.tests import test_geos test_geos.run() $ /minitage/dependencies/python-2.6/parts/part/bin/python bin/djangopy geos.py Testing WKT output. ...

Probably because it can't find the library ('c') containing that
function. ctypes needs a patch to find most libraries just by name on
Cygwin. Here are patches for 2.5, 2.6, and 3.1:
http://cygwin-ports.svn.sourceforge.net/viewvc/cygwin-ports/ports/trunk/lang/python/2.5.2-ctypes-util-find_library.patch
http://cygwin-ports.svn.sourceforge.net/viewvc/cygwin-ports/ports/trunk/lang/python2.6/2.5.2-ctypes-util-find_library.patch
http://cygwin-ports.svn.sourceforge.net/viewvc/cygwin-ports/ports/trunk/lang/python3/3.0rc3-ctypes-util-find_library.patch
Perhaps our python maintainer will consider including this when he has a
chance to update our python package.
