Hi, all, When I use the IPC, I get problem. Here is the code: #include <linux/types.h> #include <linux/ipc.h> #include <linux/sem.h> . . . sys_semctl(...); There is no compile error. Then: insmod test.o //test.o is the result module file This time I get the error message: unresolved symbol sys_semctl Who can please give me a hand? Thank you very much!
