From 7a855725f2ffde508da0c7ee01dc1bcd6e0a5d93 Mon Sep 17 00:00:00 2001 From: "Ondrej Zajicek (work)" Date: Tue, 14 Mar 2017 13:46:51 +0100 Subject: Some autoconf cleanups The patch allows to use autoreconf, replaces some long obsolete constructs and does some other minor cleanups. Also, the file configure.in is renamed to configure.ac, as the old name has been deprecated for a long time. Thanks to Ruben Kerkhof for the patchset. --- aclocal.m4 | 29 +++-- configure.ac | 335 ++++++++++++++++++++++++++++++++++++++++++++++++++ configure.in | 314 ---------------------------------------------- sysdep/autoconf.h.in | 70 ----------- tools/Makefile-top.in | 2 +- 5 files changed, 353 insertions(+), 397 deletions(-) create mode 100644 configure.ac delete mode 100644 configure.in delete mode 100644 sysdep/autoconf.h.in diff --git a/aclocal.m4 b/aclocal.m4 index 02c0f76b..f2775422 100644 --- a/aclocal.m4 +++ b/aclocal.m4 @@ -1,12 +1,17 @@ dnl ** Additional Autoconf tests for BIRD configure script dnl ** (c) 1999 Martin Mares -AC_DEFUN(BIRD_CHECK_INTEGERS, +AC_DEFUN([BIRD_CHECK_INTEGERS], [AC_CHECK_SIZEOF(char, 0) AC_CHECK_SIZEOF(short int, 0) AC_CHECK_SIZEOF(int, 0) AC_CHECK_SIZEOF(long int, 0) AC_CHECK_SIZEOF(long long int, 0) +AH_TEMPLATE([INTEGER_8], [8-bit integer type]) +AH_TEMPLATE([INTEGER_16], [16-bit integer type]) +AH_TEMPLATE([INTEGER_32], [32-bit integer type]) +AH_TEMPLATE([INTEGER_64], [64-bit integer type]) + for size in 1 2 4 8;
