Bug ID: 52444
           Summary: Regression prevent eclipse from hitting breakpoints
           Product: Wine
           Version: 7.0-rc6
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

I usually use eclipse with normal gdb for debugging. For that I compile without
mingw, since it doesn't find the symbols when using real dlls.

Since a while this is broken, and eclipse doesn't hit any breakpoints anymore.

It could possible work with winedbg, but I have absolutely no idea how to get
it to work with eclipse, it doesn't seem to be compatible. So I'd prefer the
native version of gdb to work.

A little off topic:

At least a standalone, regular linux gdb can be made loading the debug
information from the mingw-built PE files with the gdbinit.py
script by Rémi Bernon.

There is also prototype of gdb able to iterate a processes dll list (currently
just 64-bit processes) and load also the symbols from a mingw-built PE file.

Back on topic:

I tried now a windows eclipse package and a (quite old) i686 mingw windows gdb
package which kind of worked with breaking into the process but eclipse has
graphical glitches and showed most frames in winnt.h function NtCurrentTeb
(which the gdb.exe did also interactively).

Therefore just to clarify - you want (unlike my short test above) to use a
linux eclipse with a linux gdb to attach to a process running with wine
from a tree built without mingw?

Thanks, I'll look into that sometime.

Yes. I mean, technically, that is just my current workflow. What I *really*
want is to debug Wine with (linux) eclipse, using breakpoints, backtrace,
stepping and the liles.

It's just that I didn't find another way to make it work. winedbg doesn't play
nice with eclipse (or the other way round). And a mingw built doesn't work with
normal gdb either, unless you use "add-symbol-file PATH/comctl32.dll" on the
dlls manually before the breakpoint would be hit.

Still the same issue in wine-7.20. An idea how to work around this?

There is a MR to address this issue:
https://gitlab.winehq.org/wine/wine/-/merge_requests/1074

Now if only there was a way to debug multiple processes at once, for programs
that spawn child processes...
