[-- Attachment #1 --] Hello everyone, I have recently installed FreeBSD4.1, I created a new customized kernel and I created a new module under "modules"called "label". In the same time I had to modify two of the kernel files under net and inet directories(if_ethersubr.c and ip_output.c) to contain a couple of definitions and some more code. I am able to compile and link the new customized kernel, but when I try to load my new module I am getting the following errors: ********************************************************************* LSR-5# kldload label kldload: can't load label: Exec format error LSR-5# Nov 1 16:08:01 LSR-5 /kernel: link_elf: symbol lt_add_ptr undefined Nov 1 16:08:01 LSR-5 /kernel: link_elf: symbol lt_add_ptr undefined **************************************************************************** ***** The pointer the linker is complaining about is defined into the ip_output.c but for some reason it doesn't seem to be taken by the linker when I am loading the module dynamically with the command kldload. Could you give me some advice on what am I supposed to do to solve this problem? Is there a way to check if ip_output is applied? Maybe the dependecies are not created properly.. But then where am I supposed to take a look to check them? Note that I have tried these changes on FreeBSD3.3 and I didn't have any problem at all. Any suggestion would be greatelly appreciated.
