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@xxxxxxxxx> 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'.
