Re: [Sgems-devel] compilation problems on Linux

[nico r. <nic...@gm...>]

The linker is trying to link with python2.4 and can't seem to find it.
It is looking for
/home/UNINE.CH/comuniana/software/Python-2.4.5/lib/libpython2.4.so
If that file doesn't exist, modify variable PYTHON_LIB to change the
path, or PYTHON_SO to change the name of the library (omitting the
"lib" and the ".so").
>From the output of your "find" command you don't seem to have the
dynamic library installed (the python2.4.a is a static library, you
need the .so file - DLL in Windows speak). Or you're not looking in
the right directory: mine is installed in /usr/lib for example.
Hope this helps,

Nicolas
