I've been here pretty much banging my head for the past couple of hours trying to build PySFML without success on my OSX Lion machine.  I have followed the tutorial and compiled the 2.0 SFML snapshot.  I compiled the examples along with that, and those work perfectly fine.  I even re-compiled the for the static release library and the debug compilations. (Which I saw a forum post stating that was bad, but I don't know why)

Now I'm no expert to linking libraries or compiling from the command line, but when I go to compile the python bindings, I always get a linker error.  The same error occurs if I try to compile a small test file from the command line.


Here's the snippet from terminal:
Code: [Select]

bash-3.2$ sudo python setup.py build
running build
running build_ext

make sure that your Libary files are in the pythons libs folder.

I don't think that's quite it because this is an issue with GCC.  I haven't even created the bindings at this point.

*EDIT*
Well I have gotten it to work by redoing the release builds.  I'm not sure what went wrong the first time, but everything works fine now.
