Premise:
In QtCreator, I am trying to debug a library in which it [QtCreator] itself relies upon.
- I build the SO locally
- It is installed to
/home/anon/.local/usr/local/lib/libqbscore.so - Then I test by running another instance of QtCreator, and loading the library with
LD_PRELOAD:
And This is how I typically set the breakpoints:
I can reliably generate that ErrorInfo. It outputs "fungo bar" to the Issues pane in the running instance of QtCreator, which means that I have confirmed that the breakpoints are being missed.
I double checked to make sure the debug symbols were active, and the following looks fine:
file "/home/anon/.local/usr/local/lib/libqbscore.so.1.24.0"
/home/anon/.local/usr/local/lib/libqbscore.so.1.24.0: ELF 64-bit LSB shared object,
x86-64,
version 1 (GNU/Linux),
dynamically linked,
BuildID[sha1]=67ceaaa6f6054a82f50124acf14aa3b4cf3a3b71,
with debug_info,
not stripped
What I have tried:
https://stackoverflow.com/a/10448351/2158002
Under Additional Startup Commands:
set environment LD_PRELOAD /home/anon/.local/usr/local/lib/libqbscore.so
I checked the console to confirm the environment variable, and it is being set as intended. However my breakpoint does not fire.
https://stackoverflow.com/a/69537173/2158002
set solib-search-path /home/anon/.local/usr/local/lib/
Does not work.
https://stackoverflow.com/a/41822591/2158002
set exec-wrapper env 'LD_PRELOAD=/home/anon/.local/usr/local/lib/libqbscore.so'
Does not work.
Conclusion:
The obvious solutions have not worked, and relevant search results have run dry, which leads me to conclude that there is probably a simple oversight that I am plainly ignorant of. One consideration is that perhaps this will not work because the instance of QtCreator itself is not compiled with debug symbols:

Reading symbols from /usr/bin/qtcreator...
This GDB supports auto-downloading debuginfo from the following URLs:
https://debuginfod.archlinux.org
Enable debuginfod for this session? (y or [n]) n
Debuginfod has been disabled.
To make this setting permanent, add 'set debuginfod enabled off' to .gdbinit.
(No debugging symbols found in /usr/bin/qtcreator)
However I highly doubt this because I am under the impression that only the shared object needed the Debug symbols.
In any case, how can I run QtCreator's debugger, that it can properly act upon breakpoints set up for the library [ which is being loaded via LD_PRELOAD ]?
