From 50bbfb3de58e82514f50a34f2ec24d147112b7f5 Mon Sep 17 00:00:00 2001 From: Joe Orton Date: Thu, 20 Jun 2019 13:00:37 +0000 Subject: Add an --enable-reduced-exports configure option to link libmain.a using ld's --whole-archive mode and avoid building exports.c entirely. This reduces the size of a minimal httpd binary by 18% on Linux/x86_64 (687K to 560K) with no difference to the set of symbols available to modules. This option is only appropriate to use if using a shared libapr* build, hence is non-default. * configure.in: Add --enable-reduced-exports; disable httpdunit build if used. Define AP_FORCE_EXPORTS if not enabled (default) in place of AP_USING_AUTOCONF. * server/main.c (ap_suck_in_APR): Only build if AP_FORCE_EXPORTS is defined. * Makefile.in: Link libmain.la using LIBMAIN_LIB. * server/Makefile.in: Conditionally build exports.c into libmain. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1861685 13f79535-47bb-0310-9956-ffa450edef68 --- build/config_vars.sh.in | 2 ++ 1 file changed, 2 insertions(+) (limited to 'build') diff --git a/build/config_vars.sh.in b/build/config_vars.sh.in index 408e42d2cb..d586ebd4c5 100644 --- a/build/config_vars.sh.in +++ b/build/config_vars.sh.in @@ -84,4 +84,6 @@ exec sed " /^APR_INCLUDEDIR.*$/s,.*,APR_INCLUDEDIR = ${APR_INCLUDEDIR}, /^APU_INCLUDEDIR.*$/s,.*,APU_INCLUDEDIR = ${APU_INCLUDEDIR}, /^LIBTOOL.*$/s,/[^ ]*/libtool \(.*\),${APR_LIBTOOL} @LTFLAGS@, +/^EXPORTS_DOT_C/d +/^LIBMAIN_LIB/d " -- cgit v1.2.1
