Error with Geant4 sourcing #63

Closed AdityaRoot closed 3 years ago

AdityaRoot commented 3 years ago

Hi, I am installing MEGAlib on an arch linux install and have had a few errors.

Notably I changed the AllowedGeant4Versions.txt and AllowedROOTVersions.txt to install newer versions of both. With the latter this fixed the issues I was having during compilation however with Geant4 I am failing at the sourcing step.

Upon running the source command source /home/adi/MEGAlib/bin/source-megalib.sh I receive the following error: bash: cd: /usr/bin/../../../include/Geant4: No such file or directory

I looked at the code of source-megalib.sh and tried defining the different environments manually one at a time through the config/env.sh and both --root and --megalib's sources work correctly and solely geant's gives the above error. Going through env.sh, nothing looks like it would lead to the path /usr/bin/../../../include/Geant4 in the first place.

I receive this error regardless of the Geant4 version set in AllowedGeant4Versions.txt

You cannot switch the versions of Geant4 due to API changes, Did you let the MEGAlib setup script install Geant4?

AdityaRoot commented 3 years ago

Yes I let the setup script install after changing the version in the allowed versions file - I'll try changing it back (to 102) and get the error.

To confirm - it's alright however that I changed the allowed ROOT versions right? As updating that fixed an error.

AdityaRoot commented 3 years ago

Just recompiled - the compilation says success however I get the exact same error upon using the source command.

zoglauer commented 3 years ago

Yes, you can update ROOT. I am trying to install Arch at the moment in a virtual machine and try to reproduce the error. Might take a while.

The default MEGAlib install is now working on Arch with the latest version on the master branch.
