hi, in the older kernels (anything before the commit id mentioned below), there is include/Kbuild, where you can do something like this: header-y += ../../quick-hacks/kernel-modules/mymodule/ and then do a 'make headers_install' from the *source* tree, which seems to do the right thing. in newer kernels, due to 10b63956fce7f369cc37fd4d994f09bd5203efe4, you need to do the same thing in include/uapi/Kbuild... kind regards anupam On Thu, Jul 17, 2014 at 12:27 AM, Daniel Hilst Selli <danielhilst@gmail.com> wrote:
I write an out-of-tree module and now want to export its ioctls to userspace by installing a header that my modules includes, I was looking for how to do it but can't get it..
I was trying header-y from https://www.kernel.org/doc/Documentation/kbuild/makefiles.txt but got: make[1]: *** No rule to make target 'headers_install'. Stop.
Here is what I'm trying: https://gist.github.com/gkos/b0bc4e29a3147b0e6d3b
I see on kernel that usually the exported headers go in include/uapi/SOMETHING and are declared on include/uapi/Kbuild.. but have no idea if this may work for out-of-tree modules, the headers_install exists on linux Makefile so the 'No rule to make target 'headers_install'' doesn't make sense to me ..
I try follow headers_install target on kernel's Makefile but only got frustraded :(
Any idea?
ps: I compiled the module but don't loaded it, so it may have mistakes
Thanks in advance! Cheers!
