i have written a external module. i am using a Kbuid file to compile the module.this kbuild file is generating a header file which includes some configs based on the choices given during compilation of module.
i want to compile the modules files based on those configs defined in the generated header file as the same way kernel does by including the generated header autoconf.h . The problem which i am facing is the kbuild system comping the modules files first and generating the header file later.
so i have two question .
1. how can i generate the header before compiling the module files.
2.how can i define config macros for external module and reflect to .config .

thanks
