Header files

Header files are specified by the HEADERS family of variables. Generally header files are not installed, so the noinst_HEADERS variable will be the most used. 1

All header files must be listed somewhere; missing ones will not appear in the distribution. Often it is clearest to list uninstalled headers with the rest of the sources for a program. See A Program. Headers listed in a _SOURCES variable need not be listed in any _HEADERS variable.

Headers can be installed in includedir, oldincludedir, or pkgincludedir.

Footnotes

  1. However, for the case of a non-installed header file that is actually used by a particular program, we recommend listing it in the program's _SOURCES variable instead of in noinst_HEADERS. We believe this is more clear.
