ROOT 5.34.36 and PYTHIA 8.226


I try to install ROOT 5.34.36 with Pythia 8.8226 with the command in ROOT install repository
./configure --prefix=$WORK/root-5.34.36 --enable-pythia8 --with-pythia8-incdir=$PYTHIA8/include --with-pythia8-libdir=$PYTHIA8/lib

but I have any errors with the creation of file :
==> lib/ done

Can you help me, please ? Thanks a lot.


It looks like the interface of PYTHIA has changed… Could you try with an older version of PYTHIA? (I think it should work with 8201…)

Cheers, Bertrand.
