Problem linking Kernel Code

tessendor · 03-11-2011, 07:49 AM

Hey everyone,

as you might have read in my other post, I'm working on a Linux Security Module.

Currently I'm experiencing a strange problem with the linker.
Everything just compiles fine but when it comes to linking I'll get plenty of errors like
"undefined reference to 'method'"

my Makefile looks like this:

Code:

obj-$(CONFIG_SECURITY_MODULE_NAME) := module1.o
module-y := module2.o module3.o

I have tried several combinations I have seen in other LSM's Makefiles, but none of them worked for me.

What I am wondering about: there aren't any build instructions in this file (in those of the other LSMs neither) and the only .o file which is found in my plugins's directory is module1.o

Can anybody help me out?

Thanks in advance!

regards

I think you want something like this:

Code:

obj-$(CONFIG_SECURITY_MODULE_NAME) := module.o
module-y := module1.o module2.o module3.o

This assumes that you have module1.c, module2.c, and module3.c, and that you want to build module.ko.
