[geos-devel] building geos 3.2 and python2.7 module

[thomas veymont]

hello,

hope I am at the right place to ask this question.
I'm trying to build geos 3.2.2 with Python 2.7 module :

$ tar xvjf geos-3.2.2.tar.bz2
$ cd geos-3.2.2
# force 'configure' to use an alternative python interpreter
# instead of python2.4 provided with the OS
$ export PYTHON=/usr/local/python2.7/bin/python2.7
$ ./configure --prefix=/usr/local/geos3.2.2/ --enable-python
(...)
$ make

this fails with the following output....

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

... but the same is working with the system python2.4 default interpreter.

any idea about the problem ? could it be a problem with my SWIG version
(1.3.29) ?

thanks
Tom
