What type of an elf file should I use for the kernel, if I like to support modules which have to use functions from the kernel, but the kernel wont need any symbols from the modules?

Is it possible to make a elf executable file with a symbol table where are all symbols I declared global (or how to export them)?

Try not to add too much effort to your kernel: Leave it as a flat binary. Also, what kernel functions are you trying to use?

I meant... when you say "kerbel functions", do you mean things like INT 0x21, etc (interrupts)?

I mean I have a kernel function "add_module()" and I want every module to call this function for registering itself. So I need to export that label and address so that I can give the right address to the module which wants to call this function.
