Compiling a PM sample with GCC (2023)

<< < (50/52) > >>

Martin Iturbide:
Hi Dave

Thanks for the feedback. This is strange, I did the changes, and it compiled fine. Now it does not want to compile, I'm not sure what I screwed up.

Also, when it runs, the exe does not shows on the "taskbar", it shows on TOP, was there some other trick to make it show there?

I found inside MOUSPLAY.DLG a reference to "DLGINCLUDE 1 "RAFAEL.H"" but not sure if it is related to some issue.

Regards

Dave Yeo:
Hi Martin, somehow in MOUSPLAY_B2 mousedll.c is 0 bytes. Once I restored it, it compiled fine, still crashed.

Dave Yeo:
Seems you changed WinQueryDlgItemShort() to WinQueryDlgItemText(), changing it back gets rid of the crash but the program still doesn't seem to work and leaves the DLL loaded. Possibly the DEF needs adjusting to use  INITGLOBAL TERMGLOBAL like how it was? I'll test later.

Martin Iturbide:
Thanks Dave. I don't know how I lost mousedll.c. Now it compiles without error and warnings, but , yes, still does not work.
I changed the  INITGLOBAL TERMGLOBAL on mousedll, but no improvement.

Regards

Martin Iturbide:
Hello.

I just get back to compile an extra little thing. It compiles and works.
 
Can you please give me a hand with this warning?
