I checked the configure file and I do not see any options for compiling with debugging, i.e. there is no --enable-debug option. I see that the "default parameters" section of the configure file sets: gdbstub="yes" but other than that i do not see any other reference to debugging.

Also, I am working with qemu source code, which I configure, make, make install before every run.

Thank you again.

You need a qemu executable with debugging symbols. Distributed versions
are usually stripped, which means the debug symbols are not present
anymore.
A way to get the debug symbol is to fetch the source and recompile it...
