[fpc-pascal] "No debugger support" in FPC3.0.4 for DOS (go32v2)

[Lubomír Čabla]

I tested go32v2-ide-with-gdb.zip: IDE 1.0.12, GDB 7.3, FPC 3.0.4.

1. Windows 7/32-bit

fpnovesa.exe - OK
fpvesa.exe   - exit with "System does not support fullscreen mode"
fpvesag.exe  - exit with "System does not support fullscreen mode"

Tested on NB/PC with max. 2K (1920/1080) monitors.

2. real W98/DOS

fpnovesa.exe - OK
fpvesa.exe   - OK
fpvesag.exe  - OK

Tested on NB/PC with max. 2K (1920/1080) monitors.

3. Another problem is with the Intel i7-6700 Skylake 3.40 GHz and VGA Intel
Graphics 530
with 4K monitor 3840x2160.

I can not test it in Windows I have 64-bit versions only.

But in real W98/DOS it looks completely different:

fpnovesa.exe - started, but on exit I see only the cursor, program hangs
fpvesa.exe   - the program does not start, it stops
fpvesag.exe  - the program does not start, it stops

In any case, a restart is required.

But BP 7 or Norton Commander I can run without problems!

Distributed version FP.EXE/GO32V2 3.0.4 on the same computer in DOS also
just hangs,
with or without parameter NOVESA.

I hope it will help.
