And try to include asm/syscalls i'm just catching up with this thread and, if i read it correctly, the goal is to build a loadable kernel module using the proper incantation and options on the gcc command line, is that correct? but i'm not sure i see the value in that -- why not just build the module using all of the compilation infrastructure built into the kernel source Makefile and accompanying build structure? not trying to market, but i explain how to do that here: http://crashcourse.ca/introduction-linux-kernel-programming/introduction-linux-kernel-programming in the first few lessons, which are publicly available to everyone. granted, you *can* reproduce all of that manually if you want, but i don't see the point in making this any more difficult than it has to be. of course, if i've misunderstood what this thread is about, you can ignore all this. :-) rday p.s. specifically, i demonstrate how to build your first kernel module here: http://crashcourse.ca/introduction-linux-kernel-programming/lesson-4-writing-and-running-your-first-kernel-module again, that lesson is publicly available to everyone. -- ======================================================================== Robert P.
