The inability to include the uAPI headers directly in tools/ is one of the bigger annoyances of compiling user space code. Most projects trade the pain for smaller inconvenience of having to copy the headers under tools/include. In case of netlink headers I think that we can avoid both. Netlink family headers are simple and should be self-contained. We can try to twiddle the Makefile a little to force-include just the family header, and use system headers for the rest. This works fairly well. There are two warts - for some reason if we specify -include $path/family.h as a compilation flag, the #ifdef header guard does not seem to work. So we need to throw the guard in on the command line as well. Seems like GCC detects that the header is different and tries to include both. Second problem is that make wants hash sign to be escaped or not depending on the version. Sigh. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
