From 27c64db6dff88ebe9761dfe3b0c073d2a9bf2e41 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Sun, 5 Oct 2014 18:41:31 -0400 Subject: build-sys: use linux/memfd.h if available linux/memfd.h was added linux 3.17, so it might not be widely available for a while. Also, check if memfd_create is defined, for the HAVE_LINUX_MEMFD_H check to have a chance of succeeding. Also, collapse all ifdefs for memfd-related stuff, because they were all added together so there's no need to check separately. --- configure.ac | 2 ++ 1 file changed, 2 insertions(+) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index e33c8f75ac..caf1f0e54e 100644 --- a/configure.ac +++ b/configure.ac @@ -283,6 +283,7 @@ AM_CONDITIONAL([HAVE_PYTHON_DEVEL], [test "$have_python_devel" = "yes"]) AC_SEARCH_LIBS([dlsym], [dl], [], [AC_MSG_ERROR([*** Dynamic linking loader library not found])]) AC_CHECK_HEADERS([sys/capability.h], [], [AC_MSG_ERROR([*** POSIX caps headers not found])]) AC_CHECK_HEADERS([linux/btrfs.h], [], []) +AC_CHECK_HEADERS([linux/memfd.h], [], []) # unconditionally pull-in librt with old glibc versions AC_SEARCH_LIBS([clock_gettime], [rt], [], []) @@ -300,6 +301,7 @@ AC_SUBST(RT_LIBS) LIBS="$save_LIBS" AC_CHECK_FUNCS([fanotify_init fanotify_mark]) +AC_CHECK_FUNCS([memfd_create]) AC_CHECK_FUNCS([__secure_getenv secure_getenv]) AC_CHECK_DECLS([gettid, pivot_root, name_to_handle_at, setns, LO_FLAGS_PARTSCAN], [], [], [[ -- cgit v1.2.3-54-g00ecf
