Revision 12dc1bef1f53fb1abdc599fbde1e66c6ca66af62 authored by Marty E. Plummer on 09 January 2018, 05:55:04 UTC, committed by Ingy döt Net on 19 July 2018, 21:49:53 UTC
'config.h' is meant to be a convenience header to be #included at build time, but not installed. Installing it can cause a host of problems for various other projects (for instance, attempting to build u-boot from source while another project's 'config.h' exists in the compiler search path will cause build failures similar to: https://github.com/pepe2k/u-boot_mod/issues/148 Further, I've changed '#include <config.h>' to '#include "config.h"', which should constrain the search path to the current build directories, so if another package with a bugged build has this file installed, it will not cause yaml to miscompile/fail. If you have a file `/usr/include/config.h` on your filesystem, query your package manager to find out what package owns it, and file a bug report against it with your distro maintainers.
