From: Emil Velikov Date: Fri, 23 Mar 2018 17:37:39 +0000 (+0000) Subject: configure: use AC_CHECK_HEADERS to check for endian.h X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5a75019ad0270a974788a9b8648ba98ff4203768;p=mesa.git configure: use AC_CHECK_HEADERS to check for endian.h The currently we use the singular CHECK_HEADER combined with explicit append to the DEFINES variable. That is a legacy misnomer, since it requires us to add $DEFINES to every piece that we build. Using the plural version of the helper sets the HAVE_ macro for us, plus ensures it's passed to the compiler - if config.h is available in there (not in the case of mesa) otherwise on the command line. In hindsight, we should replace all the AC_CHECK_{FUNC,HEADER} instances with the plural version (or even the _ONCE suffixed version) and drop the DEFINES hacks.
