3 things: 1) Your code is buggy in 2 ways. You NEVER EVER include modversions.h directly. Esp not in the way you do. Also do not use __SMP__ but just CONFIG_SMP. If you need 2.0 compatibility do it the other way around 2) Please download http://people.redhat.com/arjanv/xircom_cb/Makefile and edit to change the filename. That will make it work. 3) If this is for a binary only module, please don't and consider making it GPL. Red Hat will be more than willing to work with you to get the hardware supported for the next release and updated kernels. |

Additional info: Note that this is a complete clean install of RH 7.2 with no updates. The same module compiles OK on a clean install of RH 7.1. Also note that if I comment out the lines regarding MODVERSIONS, then it compiles OK. // test.c #include <linux/module.h> #if defined(CONFIG_SMP) #define __SMP__ #endif #if defined(CONFIG_MODVERSIONS) #define MODVERSIONS #include <linux/modversions.h> #endif #include <linux/kernel.h> #include <asm/io.h> int init_module(void) { printk("<7>INIT - Test\n"); return 0; } void cleanup_module(void) { printk("<7>CLEANUP - Test\n"); }
