Examining a core dump via gdb

[link1305]

Hello,

Is it possible to examine a core dump from srcds using gdb (the debugging tool on linux)? I read somewhere else that it is, but gdb won't read the file:
"/servers/source/core.6691" is not a core dump: File format not recognized :o

For those interested:

The problem I have only exists on linux....it runs without issue on windows (how often can you say that? ;)). When my server mod reads a certain line in its config file, the server seg faults. The line it reads isn't very different from any other Convar I've created either - all it does is call the "SetValue()" function of a variable of type ConVar. I have about 20 convars total, and only 4 of them cause it to seg fault. Very strange problem.

Any thoughts?

All the time, especially when talking about HL2 mod binaries.

You should be able to debug using cores - or you could run srcds through gdb directly and skip over the need for the core file.

Okay, I'm debugging with gdb just by running the executable through it. After srcds crashes I can view the stack with "frame", but thats not very helpful (since I already know which function it's crashing in). I would like to view a variable, but print <variable> says "no symbol in current context". Any tips for debugging srcds mods using gdb?

The last output is 0xb1dfe003 in Cplugin::SetVar () <mod file.so> I know it crashes while executing a statement in that function (the statement is convarVariable->SetValue(1)), but while it's executing that statement I'd like to see more information about the "convarVariable" - is that possible?

Thanks!

Nevermind about that last part...after recompiling and running it again, it's displaying my variables. Still stumped :/
