Hi,

I've just installed PureBasic 6.21 on ZorinOS 17.3 (based on Ubuntu 22.04).

An old program of mine which compiles fine under macOS 15.6 (and whatever OS X version was current when I wrote this 6 years ago) fails with this error on the above Linux:

Code: Select all

[COMPILER] Line 49: Constant not found #PB_Menu_Quit.

The line in question is polling in my main event loop :

Code: Select all


; *** the includes, settings, app window opening etc are above and not shown here to keep code shorter in forum ***

; Event loop - just catch the exiting event(s)
; All other events should be module-level
Define eventNumber.i = 0

Repeat	
	
	eventNumber = WaitWindowEvent()
	
	If eventNumber = #PB_Event_Menu And EventMenu() = #PB_Menu_Quit  ; *** <= THIS IS LINE 49 ***
		PostEvent(#PB_Event_CloseWindow)
	EndIf
	
Until eventNumber = #PB_Event_CloseWindow

End

.

TBH it's been a few years since I used PB in anger, so maybe the above is not the best way to do things, but the fact that a constant seems to be missing in the Linux version is a bit of a worry.

Does anyone else have this issue or is it just me?

Thanks

Oh thanks, I had no idea these differed between OSes. Will look at the proposed solution above, thank you.
