I consulted a TFS dev as I wasn't quite sure how to do it properly. (Djarek & Ninja)

If you are following this tutorial:
github.com

Compiling on Debian GNU Linux

A free and open-source MMORPG server emulator written in C++ - otland/forgottenserver
github.com github.com

instead of just doing cmake ..

Do:
cmake -DCMAKE_BUILD_TYPE=Debug ..

If this makes the server to laggy, increase performance (but loose some information) with this instead:
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..

Remember if you already have build folder, delete it/remove all files in it and rebuilt it to make sure there are no conflicts with previous builds.

And then run the server with gdb, show the bt full when it crashes.

And...

compile the server with the -g options to enable symbols -ggdb?
Run the server with gdb
if server crashes, get the stacktrace bt full? to reveal more information.

Post that, and we should be able to figure out where in the source things went wrong.

And then run the server with gdb, show the bt full when it crashes.

And symbols should exist and tell us what is going on in our source files! :)
