commit 9feeb638cde083c737e295c0547f1b4f28e99583 upstream. In 2016 GNU Make made a backwards incompatible change to the way '#' characters were handled in Makefiles when used inside functions or macros: http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57 Due to this change, when attempting to run `make prepare' I get a spurious make syntax error: /home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator. Stop. When inspecting `.fixdep.o.cmd' it includes two lines which use unescaped comment characters at the top: \# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep) \# using basic dep data This is because `tools/build/Build.include' prints these '\#' characters: printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \ printf '\# using basic dep data\n\n' >> $(dot-target).cmd; \ This completes commit 9564a8cf422d ("Kbuild: fix # escaping in .cmd files for future Make").

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
