From 0d253d52e804a5affb0f1c851ec250071e7345d9 Mon Sep 17 00:00:00 2001 From: Tim Ruffing Date: Sun, 13 Mar 2022 10:39:55 +0100 Subject: [PATCH] configure: Use modern way to set AR This uses AM_PROG_AR to discover ar, which is the recommended way to do so. Among other advantages, it honors the AR environment variable (as set from the outside). The macro has been around since automake 1.11.2 (Dec 2011). This commit also removes code that discovers ranlib and strip. ranlib has been obsolete for decades (ar does its task now automatically), and anyway LT_INIT takes care of discovering it. The code we used to set STRIP was last mentioned in the automake 1.5 manual. Since automake 1.6 (Mar 2002), strip is discovered automatically when necessary (look for the *private* macro AM_PROG_INSTALL_STRIP in the automake manual). --- .gitignore | 1 + configure.ac | 11 +++++------ 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/.gitignore b/.gitignore index 53941f23a5..d88627d72e 100644 --- a/.gitignore +++ b/.gitignore @@ -46,6 +46,7 @@ coverage.*.html src/libsecp256k1-config.h src/libsecp256k1-config.h.in +build-aux/ar-lib build-aux/config.guess build-aux/config.sub build-aux/depcomp diff --git a/configure.ac b/configure.ac index cc766b20a3..16a4920716 100644 --- a/configure.ac +++ b/configure.ac @@ -25,24 +25,23 @@ AC_CANONICAL_HOST AH_TOP([#ifndef LIBSECP256K1_CONFIG_H]) AH_TOP([#define LIBSECP256K1_CONFIG_H]) AH_BOTTOM([#endif /*LIBSECP256K1_CONFIG_H*/]) -AM_INIT_AUTOMAKE([foreign subdir-objects]) -LT_INIT([win32-dll]) +# Require Automake 1.11.2 for AM_PROG_AR +AM_INIT_AUTOMAKE([1.11.2 foreign subdir-objects]) # Make the compilation flags quiet unless V=1 is used. m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES([yes])]) PKG_PROG_PKG_CONFIG -AC_PATH_TOOL(AR, ar) -AC_PATH_TOOL(RANLIB, ranlib) -AC_PATH_TOOL(STRIP, strip) - AC_PROG_CC if test x"$ac_cv_prog_cc_c89" = x"no"; then AC_MSG_ERROR([c89 compiler support required]) fi AM_PROG_AS +AM_PROG_AR + +LT_INIT([win32-dll]) build_windows=no
