configure adds the -Werror=missing-prototypes only if it’s supported by the compiler. Instead, I could add -Wno-error=… to CFLAGS only if it’s supported. > > and in what directory are these system headers that cause the problem? > is this directory a system header directory ? > what compiler fails to suppress warnings from system headers ? They’re not in a system header directory. It fails to build with clang when it’s added as a user include directory, but it does build with -isystem. I’ve seen this issue floating around the internet, so this would make building the decklink code a little easier. > > also: > http://clang.llvm.org/docs/UsersManual.html#controlling-diagnostics-in-system-headers > > [...] > -- > Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB > > The real ebay dictionary, page 1 > "Used only once" - "Some unspecified defect prevented a second use" > "In good condition" - "Can be repaird by experienced expert" > "As is" - "You wouldnt want it even if you were payed for it, if you knew ..." > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
