From f34d10bbe92b52c87a82bd978a15df1532745f9f Mon Sep 17 00:00:00 2001 From: Zhao Lei Date: Fri, 13 May 2016 11:44:52 +0800 Subject: [PATCH] btrfs-progs: autogen: Make build success in CentOS 6 and 7 btrfs-progs build failed in CentOS 6 and 7: #./autogen.sh ... configure.ac:131: error: possibly undefined macro: PKG_CHECK_VAR If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. ... Seems PKG_CHECK_VAR is new in pkgconfig 0.28 (24-Jan-2013): http://redmine.audacious-media-player.org/boards/1/topics/736 And the max available version for CentOS 7 in yum-repo and rpmfind.net is: pkgconfig-0.27.1-4.el7 http://rpmfind.net/linux/rpm2html/search.php?query=pkgconfig&submit=Search+...&system=centos&arch= I updated my pkgconfig to 0.30, but still failed at above error. (Maybe it is my setting problem) To make user in centos 6 and 7 building btrfs-progs without more changes, we can avoid using PKG_CHECK_VAR in following way found in: https://github.com/audacious-media-player/audacious-plugins/commit/f95ab6f939ecf0d9232b3165f9241d2ea9676b9e Signed-off-by: Zhao Lei Signed-off-by: David Sterba --- configure.ac | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index 68a37012..6b68c090 100644 --- a/configure.ac +++ b/configure.ac @@ -124,7 +124,8 @@ PKG_STATIC(UUID_LIBS_STATIC, [uuid]) PKG_CHECK_MODULES(ZLIB, [zlib]) PKG_STATIC(ZLIB_LIBS_STATIC, [zlib]) -PKG_CHECK_VAR([UDEVDIR], [udev], [udevdir]) +UDEVDIR="$(pkg-config udev --variable=udevdir)" +AC_SUBST(UDEVDIR) dnl lzo library does not provide pkg-config, let use classic way AC_CHECK_LIB([lzo2], [lzo_version], [
