MadGraph5_aMC@NLO

No Fortran Compiler detected!

Asked by Edoardo Iannucci

Hi, I'm a beginner of MadGraph, I'm trying to generate the process

g g > t t t~ t~

but I output the results on a directory "4 top" the following message appears on my terminal:

Error detected in "output 4top"
write debug file MG5_debug
If you need help with this issue please contact us on https://answers.launchpad.net/mg5amcnlo
str : No Fortran Compiler detected! Please install one

and when I open the file index.html to see the results it takes a lot of time to generate the process. Are these two problems correlated? How can I solve?

Thanks for your answer!

So madgraph does not detect a fortran compiler within your system.
So you either have to install one or change the configuration file of MG5aMC and tell him where he can find such compiler.
