Hey,
I was writing a basic hello world module. I am using Ubuntu, so I installed linux-headers package that corresponded to my kernel. It's strange because all of the examples that I saw (including from modules in the kernel itself) show things like the following for the init function:
static int netcat_init(void) { ... return 0; }
module_init(netcat_init);
However, I was not able to get it to work with "static". My hello_world_init function looks like the following:
int __init hello_world_init(void) { ... return 0; }
module_init(hello_world_init);
The command that is used to make the kernel module is the one suggested in Documentation/kbuild/modules.txt. It looks like this: make -C /lib/modules/`uname -r`/build M=$PWD
Does anyone know why the "static" version would not work?
What exactly were the errors you got?
