"Error detected in "generate_events run_01"

Did you update to gcc version 8?
We do not support such version so far.

Cheers,

Olivier

Hello Olivier,

Yes, looks like gcc auto-updated to version 8 on my computer. I now uninstalled it and installed gcc 6.3.0 and Madgraph is running fine.

Thanks a ton!

Prudhvi Bhattiprolu

Thanks Olivier Mattelaer, that solved my question.
