Strange "info threads" behaviour. (linux]

[Fabrice Gautier]

Hi,

I'm using latest gdb snapshot to debug a program using libpthread.
I compiled gdb on a debian unstable box, adn debuging my programs works
fine. Info thread return correct informations.

But my goal is to use this progrma on a embdedd linux platform.
This platform uses a STPC CPU. It has a minimal filesystem, all libs and
binaries are directly copied from the debian box. Everything is the same
version than on the debian box. Kernels are both 2.4.3, but their config
are somewhat differents.

So when i run gdb on the STPC, when i type info threads i didn't get any
info. I didn't get an error neither. I just type "info threads", enter
and i get back to the gdb prompt..

How could this be explained?

Does some missing part of the system on the STPC platform could produce
this? 

Thanks

Are you using a native GDB on your embedded platform?  If so, it could
be be that /lib/libthread_db.so.1 is missing on your embedded system.
Otherwise, I don't think that debugging multi-threaded programs
remotely is possible at all.
