Gilles,
good thing-- I just got gdb installed and I ended up getting a Segmentation
fault
0xb7e38f0d in SDLNet_CheckSockets () from /usr/lib/libSDL_net-1.2.so.0
In my makefile, how would I compile for the posix skin for Xenomai? I haven't
explicitly specified a skin.
I'm using rt_tasks and timers, synchronous messaging, as well as message queues
considerably throughout my application now and don't want to lose any of that
functionality.
Would MlockAll cause a problem potentially? It appears to be using a dynamic
library.
The error appears to occur in this snippet of code
int numready = SDLNet_CheckSockets(socketSet,0);
if( numready == -1 )
{
printf("SDLNet_CheckSockets: %s",SDLNet_GetError());
return -1;
}
Thank you,
Josh

What does gdb say ?

First you have to make sure that your program use the services it
think it uses. Do you compile your application for the posix skin ?
Does this SDL NET (library I assume) come as a dynamic shared object ?
or as a static archive ?
