Hi Mohammad

UPDATE:: I got it working now, It was just a simple path mistake.
Thanks for your help.

When i installed fairsoft, i selected the option of installing them in their source directories itself.

Here is the log file from my last installation:

It says that geant4 is installed properly. I think that there is something wrong with my libraries path.

This is the output that you asked for, in the source directory fairsoft.

I played around with the libraries and copied the geant4-config file to the spot that it wanted and now it looks like it can see geant4 or atleast most of it.

I am having some problems regarding specific files, namely the data file for low energy EM processes. I tried getting the new data file and unpacked it and placed it in the place of the old one (even though i think that they are both the same), i am still getting the same issues.
