[Gambas-user] getting Gambas version info across devices

[Brian G]

Bruce S
I am not sure what you are trying to achieve. But if you install with the installer, does it not record the info so you can uninstall. And if your building in each of those systems, don't you also have the project you can query.
I maybe don't really know what you are trying to do this  for I guess. I mean if you sense the os version and just do the apt query or zyppr query or what ever is needed  for that OS. It means a table of some kind to know which command  for the os version of course....
It would be a lot more reliable, chroot... Or some such thing...
Ummm
