I have some systems installed with default installer others have compiled
install.

It's such a variation there is no easy way to do it "properly" all the
systems work different, even the binaries are made different.

i explained completely what i am trying to achieve in the end of the last
message.
If i want to reboot into a different os to test gambas or an app then this
lists all the gambas versions i have installed on different machines so i
know what one to boot into.
(see attached image)

That's how it looks on my main os Linux-Mint

I tried chroot (got library conflicts) and various other methods before i
did it this way, believe me , i try to do it right before i just settle for
a working hack :)  (this thread pretty much covers the process)

For this application i think just how complicated it is to do a code only
sure fire way is turning out to be not worth it.

the method i have found as far as i see only has one problem that it could
possibly read a numeric only version string before a trunk version
(includes git commit hash) but so far it's 10 for 10 on the 10 systems i
have gambas installed on.

In the attached image all the "numeric only" version strings are from
packager installed gambas versions and the ones with commit hash's are
compiled installs.

Cheers for the help though :)
