Problem to load libcompiler.so plugin on NetBSD 10.1
Beesdeckar:
Hello,
I use NetBSD 10.1 and tried first to install codeblocks 20.03 binary package. Starting codeblocks freezes on libcompiler.so plugin, it outputs minimally one (or more) "Added compiler <COMPILER_NAME>" and stopped with splashscreen. When I removed libcompiler.so from plugins directory then IDE can successfully start.
After day of fighting with codeblocks building I successfully built it from source code with all plugins, but result is the same.
How to diagnose this problem ?
I looked into plugins/compilergcc how to restrict list of supported compilers to support only GNU GCC compiler, because minimally it is displayed on every start.
But I am not able to orientate in source code how to restrict number of compilers or how to see some debug messages for diagnose.
What should I try ?

Miguel Gimenez:
You can open a console and execute C::B from there, adding --verbose and --debug-log if needed.
You have compiled C::B, so you have the non-stripped executable. Execute it through GDB, when the program hangs use Ctrl-C to pause it, "where" to see the current execution point and then "continue" (if needed).
Beesdeckar:
codeblocks start outputs:

and gdb shows:

So by verbose output maybe some process was started and probably unexpectedly terminated and function

in source file cbthreadpool.cpp #182 waits for it (or for something other)... I am not sure.
What should I try ?
Beesdeckar:
I rebuild codeblocks and tried again. It freezes again in the same place like I posted above.
codeblocks starting output:
--- Code: ---Added compiler "GNU GCC Compiler"
[New process 20719]
[LWP 27145 of process 20719 exited]
--- End code ---
and When I tried display processes:

--- End code ---
Can anybody explain what happens here ?
What means
--- Code: ---[LWP 27145 of process 20719 exited]
--- End code ---
and how can help it ? Is it any problem in kernel ?
Why is (gcc) under codeblocks process like it's child ?
I found that src/src/prefix.cpp uses conditional compilation by #define BR_PTHREADS
I tried to set it to 0, it does not help.
Beesdeckar:
When codeblocks enters into freeze state described above and after it I reboot then it starts automatically after login and (of course) freezes again.
Does anybody know what is this feature for ?
Moreover I am not able to find where is command for it's automatic starting.

more diagnostic info:
I rebuild libcompiler.so with debug info and investigated another thread's stacks , not only thread displayed
by "where" command.
It is weird, that two threads try to load the same MINGW compiler and two has the same stack, why OnInit() is called in two separate threads ?
