Hi everyone,
I tried to compile build the following sample kernel module on 2.6.28 :
______________________________________________________________________ #include <linux/module.h> /* Defines the license for this LKM */ MODULE_LICENSE("GPL"); /* Init function called on module entry */
int my_module_init( void ) { printk(KERN_INFO "my_module_init called. Module is now loaded.\n"); return 0; }
/* Cleanup function called on module exit */ void my_module_cleanup( void ) { printk(KERN_INFO "my_module_cleanup called. Module is now unloaded.\n"); return; }
/* Declare entry and exit functions */ module_init( my_module_init ); module_exit( my_module_cleanup ); ____________________________________________________________________
but it fails with the following error :
_____________________________________________________________________ make -C /lib/modules/`uname -r`/build SUBDIRS=/home/satish/prog/kernel/modules modules make[1]: Entering directory `/usr/src/kernels/linux-2.6.28' CC [M] /home/satish/prog/kernel/modules/simple-mod.o In file included from include/linux/gfp.h:4, from include/linux/kmod.h:22, from include/linux/module.h:13, from /home/satish/prog/kernel/modules/simple-mod.c:1: include/linux/mmzone.h:18:26: error: linux/bounds.h: No such file or directory include/linux/mmzone.h:256:5: warning: "MAX_NR_ZONES" is not defined In file included from include/linux/gfp.h:4, from include/linux/kmod.h:22, from include/linux/module.h:13, from /home/satish/prog/kernel/modules/simple-mod.c:1: include/linux/mmzone.h:277: error: 'MAX_NR_ZONES' undeclared here (not in a function) make[2]: *** [/home/satish/prog/kernel/modules/simple-mod.o] Error 1 make[1]: *** [_module_/home/satish/prog/kernel/modules] Error 2 make[1]: Leaving directory `/usr/src/kernels/linux-2.6.28' make: *** [all] Error 2 __________________________________________________________________
any hints what could be wrong ?
Thanks Satish
