From 4f4ae6f97e210fa0a2aa274bcd2a77a226fe6a7e Mon Sep 17 00:00:00 2001 From: fanquake Date: Tue, 17 Dec 2019 22:37:13 -0500 Subject: [PATCH] build: set AC_PREREQ to 2.69 We use build macros such as AX_CHECK_LINK_FLAG, that require >=2.64, so our configure should also require Autoconf >= 2.64. The build would already blow up if 2.64 wasn't available. i.e: configure.ac:320: error: Autoconf version 2.64 or higher is required build-aux/m4/ax_check_link_flag.m4:74: AX_CHECK_LINK_FLAG is expanded from... For reference, Autoconf 2.69 was released in April of 2012. https://lists.gnu.org/archive/html/autoconf/2012-04/msg00041.html See https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Versioning.html for more info on AC_PREREQ. --- configure.ac | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/configure.ac b/configure.ac index 0df416ae3b..ad76317820 100644 --- a/configure.ac +++ b/configure.ac @@ -1,5 +1,4 @@ -dnl require autoconf 2.60 (AS_ECHO/AS_ECHO_N) -AC_PREREQ([2.60]) +AC_PREREQ([2.69]) define(_CLIENT_VERSION_MAJOR, 0) define(_CLIENT_VERSION_MINOR, 19) define(_CLIENT_VERSION_REVISION, 99)
