I copied this application from one Pc to an other,both have Ubuntu 18.04, and I want to know what I need to run it, I don't have the source only those files ? I tried to 'chmod' for the eGestion app but when I click on it nothing happens. thanks for any possible help.
you seem to have picked up an application meant for Macintosh, it does not work to just copy an Application folder or installed App to ubuntu and try to run it.
the Application has been compiled for a specifict target, it will not work for a whole other target for which there is a whole seperate compilation process.
try open a terminal and run it from there
