Hi All, I need to call sys_mknod from a module and I did the following things in module #define#define __KERNEL_SYSCALLS__ #define __KERNEL__ #define MODULE #include <linux/kernel.h> #include <linux/module.h> #include <linux/unistd.h> #include <linux/ctype.h> #include <linux/fs.h> extern asmlinkage long sys_mknod(const char *name, int mode, dev_t dev); And when I try to call this systemcall, I do sys_mknod(MYDEVICE_NAME,S_IFBLK|S_IRUSR|S_IWUSR,MKDEV(major_num,0)); in which major_num is obtained by calling register_chrdev call. The modules get compiled properly without any errors but when I try to load module, it gives me an error : ./Chardev.o: unresolved symbol sys_mknod The compiler couldnot able to find the function while linking with Kernel. Please guide me how to proceed further. Regards Dinesh ________________________________________________________________________ Yahoo!
