From 00979402230e659fff57dec612f60987665157fa Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Wed, 9 May 2018 16:32:12 -0700 Subject: [PATCH] configure.ac: Check for grep with AC_PROG_GREP Perhaps with a new version of autoconf, I began seeing: | checking the name lister (/usr/bin/nm -B) interface... ./configure: line 6973: External.*some_variable: command not found | BSD nm This is because AC_PROG_NM expands to ... if $GREP 'External.*some_variable' conftest.out > /dev/null; then lt_cv_nm_interface="MS dumpbin" fi ... I'm not sure if it's a bug in AC_PROG_NM that it doesn't call AC_PROG_GREP, but it's easy enough for us to do it. --- configure.ac | 1 + 1 file changed, 1 insertion(+) diff --git a/configure.ac b/configure.ac index c0fbfe94135..4bb89607e2d 100644 --- a/configure.ac +++ b/configure.ac @@ -119,6 +119,7 @@ dnl other CC/CXX flags related help AC_ARG_VAR([CXX11_CXXFLAGS], [Compiler flag to enable C++11 support (only needed if not enabled by default and different from -std=c++11)]) AM_PROG_CC_C_O +AC_PROG_GREP AC_PROG_NM AM_PROG_AS AX_CHECK_GNU_MAKE -- 2.30.2
