How to use gdb for debugging?

[Shiva-Gantha]

Hi,

I am new to UERANSIM, and I would like to use gdb for debugging. When I run gdb using the command:
sudo gdb nr-ue
and add try to add a break statement, it says "No symbol table is loaded."

I have added the following line in the makefile and recompiled:
CFLAGS= -g -Wall -Wextra as mentioned here

But it still says "No symbol table added".

Please guide me on how to use gdb with UERANSIM.

Thanks!

I figured it out.
In the /cmake-build-release/CMakeCache.txt
I changed the CMAKE_CXX_FLAGS:STRING=-g, so that by default all the builds can be debugged using gdb

I understand there is a way to build UERANSIM in debug mode, and if we do that, this above change will not be required. But I could not find how to do so.

You can also build UERANSIM in debug mode. Please see our makefile. I commented out 2 lines for debug builds.

You can switch between debug and release modes by editing the makefile.

Yes. I see it. Thanks!
