MadGraph5_aMC@NLO

Command "launch auto " interrupted with error:

Asked by James

Hi! I just have a quick question, it's probably something simple but I can't figure out why this won't launch. The same file launches fine on my personal computer, but not when I'm logged in to our local cluster. This is the error I get when I try to launch any process in mg5:

Command "launch auto " interrupted with error:
MadGraph5Error : A compilation Error occurs when trying to compile /home/james/eve/Source.
 The compilation fails with the following output message:
     rm -f ../lib/libdhelas.a
     cd DHELAS; make
     make[1]: Entering directory `/home/james/eve/Source/DHELAS'
     gfortran -O -fno-automatic -ffixed-line-length-132 -c -o aloha_functions.o aloha_functions.f
     /usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.9.1/f951: error while loading shared libraries: libmpc.so.3: cannot open shared object file: No such file or directory

     make[1]: Leaving directory `/home/james/eve/Source/DHELAS'
     make: *** [../lib/libdhelas.a] Error 2

 Please try to fix this compilations issue and retry.

Does anyone have any ideas what could be causing this?

Thanks in advance!

Hi,

This is a compilation error. So the reason is that you do not have the same compiler on your local machine and on the cluster.
Did you try some LO or NLO computation.
for NLO computation we need gfortran 4.6 at least.
for LO computation, if you use the version 2.3 then you need gfortran 4.4. If you use an older version, then 4.1 should be enough.

Cheers,

Olivier

Hi Olivier,

Thanks for the quick response! That's actually what I thought at first too, but my version of gfortran is actually 4.9.1 which is well above 4.6 (I am doing NLO computations) My g++ compiler is 4.9.1 also. Is there anything else that needs to be updated that I could be missing?

Thanks

Actually the error message seems to be a gfortran internal error:

/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.9.1/f951: error while loading shared libraries: libmpc.so.3: cannot open shared object file: No such file or directory

So looks like that one fortran library can not be found.

Here you will find a solution:
http://stackoverflow.com/questions/17425982/cannot-open-libmpc-so-3-while-making-gcc4-8-1
But looks like it requires to be sudo.
So I guess that you will need to contact your IT team.

Cheers,

Olivier
