Re: Python on Mac OSX

Hi,

Sorry, a typo.

        import ROOT
works but

        import PyCintex
does not.

No; there should be no Cint mismatch - everything was built consistently, from source.

I also have problems building the python libraries in the first place. If I build ROOT 5.16 from source on a standard OS install of Python 2.3.5, this works out of the box.

If, however, I use a more modern version of MacPython (2.4.4), then the ROOT build doesn't work. However, I can get a working PyROOT library by following the instructions in https://savannah.cern.ch/bugs/?22003, namely building a custom library with:

cd pyroot/src
g++ -flat_namespace -bundle *.o -bundle_loader /Library/Frameworks/ Python.framework/Versions/Current/bin/python2.4 -L$ROOTSYS/lib -lCore -lCint -lHist -lGraf -lGraf3d -lGpad -lTree -lMatrix -lReflex - framework Python -o $ROOTSYS/lib/libPyROOT.so

Here's the (slightly more detailed) dump when I do the latter: (ROOT 5.14.00f with PYTHON 2.4.4, which I'm doing in a vain attempt to compile GAUDI).

The line that is failing is:
Cintex = libPyROOT.MakeRootClass( 'Cintex' )

I have no idea what this does; I'm new to the whole Python interface thing.
