There are many ways users may compile samples, some of them got broken by commit5f9380572b("samples: bpf: compile and link against full libbpf"). Improve path resolution and make libbpf building a dependency of source files to force its build. Samples should now again build with any of: cd samples/bpf; make make samples/bpf/ make -C samples/bpf cd samples/bpf; make O=builddir make samples/bpf/ O=builddir make -C samples/bpf O=builddir export KBUILD_OUTPUT=builddir make samples/bpf/ make -C samples/bpf Fixes:5f9380572b("samples: bpf: compile and link against full libbpf") Reported-by: Björn Töpel <bjorn.topel@gmail.com> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
