Thanks for the answer.

Yes, I saw that tread but did not solve my problem.

At the end I solved it by simply making by hand the directory: pylib/lib

before compilation.

Hi,

Sorry for the hijack but I'm also getting the same error.

All of the four combinations of makefile options suggested in the other thread also don't solve the issue.

If I try making 'pylib/lib' by hnad, I get the error:

ar: ../lib/libpythiaext.a: No such file or directory
make[1]: *** [../lib/libpythiaext.a] Error 1

Hi Jamie,

Looks like my answer (made a couple days ago) didn't reach the launchpad server... So I put it back.

Such bug should definitively be fixed in the next version of MG5 (1.5.12)
In the mean time, the solution to manually compile is the following
cd pythia-pgs
make clean
cd libraries/pylib
mkdir
make clean
make
cd ../../
make

Cheers,

Olivier
