As another people asks, I put the code. It is really simple. It make an oops(when I do a: cat /proc/titux), but my problem isn't there for the time. Yet, I have done the test with an hello world mdoule without MODULE_LICENCE and I have had the same result. /* proc_test.c */ #include <linux/module.h> #include <linux/proc_fs.h> #define MODVERSIONS MODULE_LICENSE( "GPL" ); MODULE_AUTHOR( "titux" ); static int titux_read_proc( char *buf , char **start, off_t offset, int count, int *eof , void *data ) { int len = 0 ; buf = kmalloc( 128 , GFP_USER ) ; len += sprintf( buf + len, "current pid: %i\n", current->pid ); *eof = 1 ; return len ; } void init_module() { printk( "proc_test loaded... ok"); create_proc_read_entry( "titux", 0, NULL, titux_read_proc , NULL ) ; } void cleanup_module() { printk( "proc_test unloaded... ok" ); remove_proc_entry( "titux", NULL ); } /* Makefile */ KERNELDIR = /usr/src/linux CC = gcc include $(KERNELDIR)/.config CFLAGS = -D__KERNEL__ -DMODULE -I$(KERNELDIR)/include -O -Wall all: proc_test.o proc_test.o: clean: rm -f *.o *~core -- Cordialement/Regards +-------------------------------------------------------+ | Christophe Lucas -- IOMEDA SA (clucas@iomeda.fr) | | Developpeur/Administrateur GNU/Linux | +-------------------------------------------------------+ | http://titux.tuxfamily.org -- Registered User #271267 | +-------------------------------------------------------+ -- Kernelnewbies: Help each other learn about the Linux kernel.
