By define at the command-line, I meant -DPYTHON_LIBRARY=wherever when running cmake.
Don't worry about the eigen3 warning. If Eigen3 is found, it uses that in preference to Eigen2. Just a note, to force a Python rebuild, use "touch src/scripts/openbabel-python.i". If you use "VERBOSE=1 make" you will see the command-line used to compile the Python bindings. If you still can't figure it out, please attach your CMakeCache.txt. - Noel On 19 February 2013 13:38, Peter Maas <peter.m...@specs.net> wrote: > Hi Noel,**** > > ** ** > > Thanks for your suggestion.**** > > I checked the variables in CMakeCache.txt and all are pointing to the > right (system) Python.**** > > If set the parameters as environmental setting and redid everything but > the same error comes up.**** > > I’m not sure what you mean by “define them at the command-line”**** > > Do you mean at the cmake command line or the make command line.**** > > ** ** > > Something else I noticed.
