Can not find solution

I am using linux and I can get the basic model to run. Each time I type “gams trnsport” the following output is produced

— Job trnsport Start 10/08/17 18:49:11 24.9.1 r63795 LEX-LEG x86 64bit/Linux

I also have a trouble about this subject.I tried to solve my optimization problem in workstation (DELL computer) , but after the ‘Executing CPLEX’ line there was no progress. The simulation is neither running nor stopping. Can anyone help me to solve ?

Thank you in advance for any help or suggestions!
