Error code 136 - cannot run FLUKA

Dear @Panos13

it may be the the MacPorts environment is corrupted.
Maybe you can try to wipe all installed ports and reinstall.

Please give a look at this thread

Fresh Install of FLUKA and FLAIR on MacOS Sonoma 14.1

Dear @RJacob The mixed environment MacPorts / HomeBrew can lead to inconsistencies. Better to avoid and – if you need to use both – be sure that the environment PATH in the Terminal where you use FLUKA/Flair includes MacPorts executable directories first (as you have done): PATH=/opt/local/bin:/opt/local/sbin:$PATH Even with that, there’s no guarantee you wont’s run into issues. Based on past experience, the MacPorts migration from an old OSX version to a newer one can leave inconsistencies …

And let us know if it works.
Cheers Luigi
