Don't worry about the second error, that was just to demonstrate that after removing lpthread from compile switches, the program compiles. I'm using Ubuntu 12.04 if that provides any help, the debian package xeno-config also gives that deprecated error so that may just be a problem with the debian package. - Vikram ^ permalink raw reply [flat|nested] 7+ messages in thread

Things you can try: - try and compile a simple example not using xenomai, calling pthread_cancel and linking it with -lpthread, passing -Wl,-t on gcc command line to see what libpthread.so is used. - when you compile xenomai, look at how for instance cyclictest is compiled, and see if the flags used to compile your examples are the same. -- Gilles. ^ permalink raw reply [flat|nested] 7+ messages in thread
