Hello Pierre, I've been doing some work on the Python bindings getting them to work on MacOSX 64-bit. Please try our development code (trunk). You will need to recreate the bindings using -DRUN_SWIG=TRUE with a recent version of Swig (>=2.0.1) on the path.
You should also "grep -i python CMakeCache.txt" and check that all of the Python related variables are pointing to the same desired Python installation. If not, you can edit CMakeCache.txt directly or else specify the correct values when calling CMake. - Noel On 10 November 2011 20:58, pierrelb <[email protected]> wrote: > I'm running OSX 10.6.8, and I'm having trouble installing openbabel with > python bindings.
