Thank you @vasilis, it is working now. I tried with deb packages, there is no issue.
Just to understand completely, if I use the source tar files, then we have to do the following:
cd flair-geoviewer-3.2
make -j 8 (depending on the no of cores)
After that, do I have to use both the following commands or only the last one? make install install-bin install-mime
make install DESTDIR=/home/riya/CERN_FLUKA/flair-3.2
When we use deb packages, flair file is created in /usr/local/flair.
Will this command create flair directory in the local as well ? make install DESTDIR=/home/riya/CERN_FLUKA/flair-3.2
