Re: Pythia6 problem on Mac OS X Tiger

Hello Rene,

Well the files are in tarball, but you have to compile them to make and libPythia6.dylib. That's exactly what I did and it also works just fine in CINT however it doesn't work when I try to compile it.

The versions I use are:
maku:~/Downloads/pythia6 toruonu$ g77 --version GNU Fortran (GCC) 3.4.4

And as I don't use gcc-4.0.3 then what else could be the problem? I tried reorganizing the library reference on the command line hoping it would cure the unresolved symbol, but no... is there a way to check which symbols are in which libraries in Mac OS X so that I could check if they are in the libraries?
