Error upon launching the output

Asked by Ajdin Palavric

Greetings!

I installed MadGraph for the first time today, as I intend to use it to compute some calculations for my Bachelor's thesis. First of all, I wanted to follow the tutorial and generate the process p p > t t~. Everything went fine and I managed to create the output directory, but when I try to lunch it, this is what I get:

Error detected in "generate_events run_01"
write debug file /home/ajdin/Dokumenta/Madgraph/qed1/run_01_tag_1_debug.log
If you need help with this issue please contact us on https://answers.launchpad.net/mg5amcnlo
MadGraph5Error : Impossible to compile /home/ajdin/Dokumenta/Madgraph/qed1/Source directory
 Trying to launch make command returns:
     [Errno 2] No such file or directory
 In general this means that your computer is not able to compile.

I am using Ubuntu 18.04 and I have gcc, g++ and gfortran installed. Do you know what could possibly be the problem? I am aware that I am missing a lot since this is my first time running the program and trying to generate the events. I would really appreciate your hints and help! Thanks in advance!

Looks like you are missing gmake package (i thought it was by default on all unix distribution but looks like not in your case)

Cheers,

Olivier

Thank you so much for your reply!

Now I managed to launch the generated output without the error mentioned previously. What I now get after launching the output file is the following:

This newly created .html page shows the cross section, errors, number of events and luminosity.

I would just like to ask does this mean that the process was executed successfully and do I have to install some other additional packages in order to run the process properly?

Thank you very much for your reply!

The warning/error that you see are related to firefox opening.
This is completly irrelevant for the physics.
If you change the configuration option (input/mg5_configuration.txt)
and set automatic_html_opening on False, you will not see those warnings anymore.

Congrats for your first run with MG5aMC^^
