PBv6.21 arm64 Trixie - Assembler error 'PB_FreeGtkBase'

[PeDe]

I use PB v6.30 beta versions with Raspberry Pi OS (Debian 13, Trixie, arm64) without any problems.
Now I wanted to use PB v6.21, but when running code in the IDE, I always get an error message.

;PureBasic - Assembler error
;error: implicit declaration of function 'PB_FreeGtkBase' [-Wimplicit-function-declaration]
; 341 | PB_FreeGtkBase();

Is PB v6.21 no longer compatible with Trixie?

May be it was a bug fixed in 6.30. We didn't changed the build system for 6.30, it still build on raspberry debian 12, so it shouldn't have any impacts between 6.21 and 6.30

I have also installed Debian 13 (Trixie) for ARM64 on my Raspberry PI5 desktop.
PB v6.21 and PB v6.30

It works for me.

Perhaps not all required developer packages are installed. Simple Install of PureBasic ...

The WebGadget or WebViewGadget is currently not working because we need different versions of PureBasic v6.30 for Debian 12 (libwebkit2gtk-4.0-dev) and Debian 13 (libwebkit2gtk-4.1-dev).

I installed everything that is possible and available according to the instructions. This did not change the error message.
I have the ‘Raspberry Pi OS Full’ version, but have not installed any other programs except Grsync and Gpartet.

When I disable the compiler option ‘Create threadsave executable’, I can run the code in the IDE. With the option enabled, I get the error message.

Stimmt.

PB v6.21:
Bug Linux C-backend Intel and ARM with ThreadSafe in PB_EndFunctions

void PB_EndFunctions() {
PB_Event_Free();

Thanks, that works.
But why does ‘!#define...’ have to be in a procedure? And is the call there so that the procedure isn't optimized away?

Peter

It was a little tricky to ensure that the C macro was defined before PB_EndFunctions. Therefore, it was implemented as a procedure.
The call is really there to prevent it from being optimised away.

[Fred]

This should work, I don't think the procedure is needed here

[PeDe]

No, without the procedure, the error occurs again.

Hallo Fred,
The C macro is otherwise only defined after PB_EndFunctions. As a procedure beforehand.
See "purebasic.c" file

[Fred]

I see ! Or use HeaderSection from 6.30
