MadGraph5_aMC@NLO

running problem on macosx

Asked by pietro govoni

Dear Madgraph_aMC@NLO experts,

I am trying to run a trivial event generation at LO and I fail miserably, when simply doing:

generate p p > Z
launch
0
done

The operative system is macosx 10.15.3,
the Madgraph release is 2.7.2.

The error I get ends with

     gfortran -o gensym symmetry.o idenparts.o -L../../lib/ -lmodel -lgeneric -lpdf -lc++ -mmacosx-version-min=10.8
     ld: library not found for -lc++
     collect2: error: ld returned 1 exit status
     make: *** [gensym] Error 1

and the full log file may be found here:

https://www.dropbox.com/s/wx5ywk4cgcn8ci3/run_01_tag_1_debug.log?dl=0

Would you please help me solving it?

Best regards,

pietro

Did you try to run
xcode-select --install

If yes this should be related to your version of xcode.
I am using 11.3.1

Cheers,

Olivier

Dear Olivier,

I updated all the updatable of XCode today, including the command line tools.
I am using the version 11.4.1 of it,

Maybe something new in 11.4.1...
I do not find anything online yet on that issue.

The only suggestion that I found is this link:
https://trac.macports.org/ticket/49177 <https://trac.macports.org/ticket/49177>
but does not sounds promising.

Cheers,

Olivier

Thanks Olivier,

sorry for the late reply. Indeed I tried today the solution of that thread (of 5 years ago), I did not manage. I hope that sooner or later the problem will be fixed!
