hi !

Code:

can_send.o: In function `main':can_send.c: (.text+0x428): undefined reference to `mlockall'collect2: ld returned 1 exit status

Hum, after some reflexion, this looks like some missing library !!!

The function "mlockall" should be a part of a library (sorry, i don't know which one), and this library might be missing...
I think you have to check where this function is from, and if this library is well cross compiled...
If all this conditions are ok, verify that the library is accessible by the cross compiler !!!!

Good luck !!

hi,
on you're log, I see that the package is already unpacked...
Do you made it yourself (with ltib -m prep -p can4linux), or it was unpacked on a previous complete build ?
If it's the second choice, try to delete this folder (rpm/BUILD/can4linux) before trying, once again...
The reason can be that you stop the compilation before it ends and, without luck, you stop it while it was unpacking this package... So the folder exists, but there's not all sources inside...

Good luck !

I haven´t solved the problem,  but it´s nice to have people ready to help!

i have tried what you said but I always find the same problem, also when I try installing many other packages....

If you have any other idea...

Nevertheles, thank you very much!!!
