Problem using LHAPDF with Pythia6

Dear Junaid,

We are not the author of Pythia (6 or 8). It will be therefore better that you contact them directly.
However not that Pythia6 is not supported anymore and that it is likely that the answer of the author will just be
install Pythia8.

Now a quick look at your log file seems to indicate that you did not have modify the makefile in order to link the code to lhapdf

Cheers,

Olivier
