Dear all,

I have some trouble during pythia compilation.

I'm trying to compile pythia scripts using july09 fairsoft version
under etch64 bit machine.

When I do ./job.sh example, I have got following error messages.
First and last sentences look like this....

Quote:

I think that I have a problem to access g77 fortran compiler.
I found already cernlib in
export CERN_ROOT=/cern/2006-etch64-g77

I guess that I have to set this path in job.sh....
Could you probably show me how do I to perform that in job.sh?

It seems that pythia between the external packages is compiled with gfortran, while you are using cernlib (CERN_ROOT) compiled with g77.
Try to use gfortran for both.

Dear all and stefano,

Changing from g77 to gfortran works!
Compilation seems to be OK, I have an executable file.
But just one warning sentence, something like this.
