You will have to rebuild the kernel and switch on this option. BUT, my kernel was built with IPC support !! This silly program works fine : #include <sys/types.h> #include <sys/ipc.h> #include <sys/shm.h> void main(void) { int shmid, result; shmid = shmget(IPC_PRIVATE, 1024 * 1024, (SHM_R | SHM_W)); printf("shmid = %d\n",shmid); result = shmctl(shmid, IPC_RMID, 0); printf("result = %d\n",result); } shmid = 2305 result = 0 Whats wrong ? Any suggestions ?? Thanks in Advance, Andre -- Andre A. Parmeggiani [EMAIL PROTECTED] ************
