Compilation error in VBF

[Nicolas Schalch]

Hello

I am using the latest version of Madgraph and I am interest in a fixed order study of VBF. The command I used are

import model loop_qcd_qed_sm_Gmu
generate p p > h j j $$ w+ w- z [QCD]
output test_VBF_NLO
launch

Then, I switch off the shower and turn on fixed order

The following switches determine which programs are run:
/================== Description ===================|================= values ============================
| 1. Type of perturbative computation | order = NLO | LO |
| 2. No MC@[N]LO matching / event generation | fixed_order = ON | OFF |
| 3. Shower the generated events | shower = OFF | PYTHIA6Q|PYTHIA6PT|PYTHIA8|HERWIG6 |
| 4. Decay onshell particles | madspin = OFF | ON|onshell |
| 5. Add weights to events for new hypp. | reweight = OFF | ON|NLO|NLO_TREE|LO |
| 6. Run MadAnalysis5 on the events generated | madanalysis = Not Avail | Please install module |
\=======================================================================================================

and I start the run with the default parameters. Unfortunately, I get a compilation error which is very long, but this is at the end

A compilation Error occurs when trying to compile /home/schalchn/Documents/software/MG5_aMC_v3_4_1/test_VBF_NLO/SubProcesses/P0_usx_husx.
The compilation fails with the following output message:

Thank you in advance for any help!

Dear Nicolas,

Which version of MadGraph5_aMC@NLO are you using?

best,
Rikkert
