I’m new on fluka and flair and I installed on virtual machine (virtual Box with Ubuntu).
When I run my files or example files from FLUKA I have an error about gfortran version which is not compatible.
I tried with gfortran version 11 and 9.5 but the error is still here.
Thank you very much for your prompt reply.
I found my mistake, I had installed fluka with a tgz file and the problem came from that.
I installed again fluka but with a deb file and it works.
