From 7ec573661ff046f6fa97d694de7a68dede2532fd Mon Sep 17 00:00:00 2001 From: Jeremy Jackson Date: Wed, 21 Jan 2009 22:10:40 -0500 Subject: [configure] fix check for GNU awk/gawk to abort ./configure if missing It also prints what were comments explaining why gawk is necessary, and not-in-PATH to help user figure out why it's not found. Build was mysteriously failing with the old version of this check when gawk wasn't installed. --- configure.ac | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index 63cef65b..db36d5ed 100755 --- a/configure.ac +++ b/configure.ac @@ -21,9 +21,11 @@ AC_CANONICAL_TARGET() AM_INIT_AUTOMAKE(1.6) AM_CONFIG_HEADER(config.h) -dnl GNU awk is required for lib/memtype.h made by memtypes.awk. -dnl BSD awk complains: awk: gensub doesn't support backreferences (subst "\1") -AC_CHECK_PROG([GAWK],[gawk],[gawk],[/bin/false]) +AC_CHECK_PROG([GAWK],[gawk],[gawk],[not-in-PATH]) +if test "x$GAWK" = "xnot-in-PATH" ; then + AC_MSG_ERROR([GNU awk is required for lib/memtype.h made by memtypes.awk. +BSD awk complains: awk: gensub doesn't support backreferences (subst "\1") ]) +fi AC_ARG_VAR([GAWK],[GNU AWK]) dnl default is to match previous behavior -- cgit v1.2.1
