gdb doesn't link to source

Hello, i'm having problems with my debugger. even with a fresh install the debugger fails to highlight the breakpoints. it does stop at breakpoints, only without any information about the line number or source file.
Using Codeblocks 20.03, compíling with -g.
even using the default console app right after a fresh install, with a breakpoint on line 7:
--- Code: ---cout << "Hello world!" << endl;
--- End code ---
gives me this output:
--- Code: ---[debug]Starting program: C:\codeblocks\prj\work\bin\Debug\work.exe

I suspected it could have something to do with permissions, but i tried a couple of different users, in different project folders, and changed ownership of files.
been looking around online for some time now but found nothing.
BlueHazzard:
Are you sure you are compiling and running the debug version of your project?
What is in the build log if you make a rebuild? Is the -g present?
Are your compiler and debugger compatible? the right version?
Does the compiler, debugger and your program have the same bit version (all 64bit, or all 32bit)?
sydnytt:
thanks for replying!
rebuild log:
--- Code: ----------------- Build: Debug in example (compiler: GNU GCC Compiler)---------------
g++.exe -Wall -fexceptions -g -c C:\codeblocks\prj\example\main.cpp -o obj\Debug\main.o
g++.exe -o bin\Debug\example.exe obj\Debug\main.o
Output file is bin\Debug\example.exe with size 1.50 MB
Process terminated with status 0 (0 minute(s), 0 second(s))

gdb and g++ are (default after install) both 64bit.
It seems however that my program is 32bit
I cannot compile with the -m64 flag:
--- Code: ---C:\codeblocks\prj\example\main.cpp:1:0: sorry, unimplemented: 64-bit mode not compiled in
--- End code ---
is this the problem? mingw64 not included in codeblocks installer?
BlueHazzard:
This should only be a problem that you can not stop the debugee...
can you post a full log of the debugger?
You have to turn it on in Settings->Debugger->Full log

alright, here is full debug log:
