Please support debugging under Haiku OS

Martin, as you see in this topic, user cannot debug the CudaText in
Lazarus,
https://github.com/Alexey-T/CudaText/issues/3374#issuecomment-
981798509

"Debugger error
Ooops, the debugger entered the error state
Save your work now!
Hit Stop, and hope the best, we're pulling the plug.
The debugger failed to get the application's PID.
This may be caused my missing debug info."

The debug-info was added then, as 'embedded', and it don't help.

On some OS pid values either look weird, or gdb uses yet another
command to get them.

I can try to have a look, but for that I need a log file

ug_session

Google says Haiku has a POSIX api. Maybe FpDebug works? (if fpc thinks
it compiles for linux, or if the IDE sets defines to activate Linux
code....)

Martin, I may ask the user about logs but maybe it's hard for him to
test it (and to activate FpDebug), so it will be better if _you_ take
a look. Haiku OS can be installed for 10-30 min, maybe take a look at
it?

Sorry, but I don't currently have the time to test this myself.

To clarify, if I get a log, this also means it depends on how exactly
it fails.
- Might be just adjusting a search pattern => ok
- Might be a lot more => then I don't know if/when I can deal with it

Another thing, the first google hit on haiku gdb
https://discuss.haiku-os.org/t/gdb-10-2-for-haiku/10876
suggests gdb does not actually work ...

---
Btw, maybe there is a workaround

In the debugger options/ property grid
  InternalStartBreak = gdbsNone

Might avoid the pid check.
Might also have side effects, that the pause-button does not work, and
breakpoints can not be changed while the app runs / not sure.


Or, instead of running in the debugger: run without debugger, then
attach. (Again not tested)

Hello.

First Initial release of Haiku was in 2002.
And the last release is still a Beta release.

Are there here Haiku users that may tell us what advantage has Haiku
vs Linux or FreeBSD ?

Thanks.

Martin,I guess I must wait for you. User answers not fast, sometimes
with 10 days delays, he is busy.

Ok, ok, sorry ( I never met a Haiku user and I would like to know what
he looks like... ).
