#38 gthwg freeze using Harbour 3.4

[José M. C. Quintas]

I compile using this:
test1.prg
../../../hwgui.hbc
-lgthwg
Show window, freeze, and close window after some seconds.

Unrecoverable error 6005: Exception error:

Harbour 3.4, Victor's fork?
I never tried it. I use 3.2 and gthwg looks normally here. I compiled with it few console applications and they works without problems.
Probably, there are some changes in GT layer, which give such result. I will review 3.4 GT modules if I will have a spare time for it, but I can't promise that this will be soon.

Only today I test using Harbour 3.2.0dev (r2104281802) nightly version.
hwgui R2985
rebuild all hwgui using hbp
rebuild contrib using hbp
compile test1.prg using same hbp

same error using Harbour 3.2

Windows 10 may/2021

I use \harbour folder as default, then:
rename \harbour to \hb34 (to disable it)
rename \hb32 to \harbour (to enable it)
Each one has it's own mingw compiler
Use -rebuild to recompile hwgui, hwgui\contrib and hwgui\contrib\gthwg\tests

try changing order too.

test1.prg
-lgthwg
../../../hwgui.hbc

[Alexander S.Kresin]

Hm... I use bcc and all works normally with it, even such applications as hbedit.
But now I've tried it with mingw and get the same error. Strange... I'll dig in it.

[Alexander S.Kresin]

Due to some dark) reasons, the gtgui was registered as a main gt driver in mingw compiled apps.
I've added two empty functions hb_gt_gui() and hb_gt_gui_default() to hthwg code to prevent this beviour. It seems Ok now.

[José M. C. Quintas]

some libraries create hb_gtsys on own library, and add ANNOUNCE HB_GTSYS on that source.
This forces a default gt. (on user side too).
Other libraries add -gtgui on commands to link, or REQUEST HB_GT_GUI.
Not sure on Harbour, because -gui assumes gui default for Windows (WVT) or Linux (GTK).
I will make new tests, including use of hb_gtsys and annouce hb_gtsys.

[José M. C. Quintas]

R2986 solve problem.
This ticket can be closed.
Test using Harbour 3.4.

i build hwgui apps, but all works on windows 7 sp1 and get error in windows 10, the logs od building is:

[Alexander S.Kresin]

These warnings may be ignored.

[Marco]

Yes, ok for the warnings but the strange thing is that app run without problem in windows 7 64 and don't run on windows 10 with errors like first message in the thread...

[José M. C. Quintas]

These are warnings, using compilation -w3 -es2.
You can reduce check to -w1 or -w0.
Are you compiling using same configuration on both Windows?

About the first error: I am with problems using GTWVG on Windows 10, may be anything changed on Windows 10 OS. Same application can runs all time ok, but for any reason, get error eventually. "1" + "1" (result of a function with fixed value) cause type mismatch error, and there are another errors too. It is a crazy thing.

[Alexander S.Kresin]

don't run on windows 10 with errors like first message in the thread...

Do you build hwgui from sources or use ready binaries? If the second, maybe, the problem is that the library is built with another mingw version. I just suppose, I haven't other ideas, it works normally on my windows 10 system.
