Problems Linking lhapdf-5.9.1 on MG5 v2_3_2_2

Hi Richard,

My guess is that the pdf are not compiled with the same compiler as the one that you use for MG5.
I’ll be back on Monday, we can look at that together if you want to.

Hi Richard, Olivier,

Was the issue resolved after reconfiguring LHAPDF?

I am having the same issue on Mac (el capitan), while default pdf don't have a problem. I have home-brew installed gcc-4.9.3, MG5-2.3.3 and LHAPDF-6.1.5. I can't seem to resolve this by reconfiguring LHAPDF?

Best,
Zhuoni

Recompiling the LHAPDF libraries solved my problem.

best,
richard

Otherwise

For LHAPDF 6.1.5, the compilation is also working nicely with the built-in clang.
So you do not need to install gcc at all actually.

Cheers,

Olivier

Hi,
I solved this by reinstalling lhapdf and compile it with my default gcc/gfortran on the machine.

My guess is that the homebrew installed version of lhapdf was somehow picking up a different compiler, even though I defined my default gcc/gfortran in the login ".bash_profile" file.
Anyway it's working now.

Best, Zhuoni
