From 89bf03c9a1b11b75d7c9e44593493017bf8a3b99 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Mon, 24 Jan 2011 11:07:51 -0700 Subject: [PATCH] build: speed up configure for releases Since most users won't be building with GNULIB_POSIXCHECK defined in CFLAGS, and since we can make ./configure 10% (several seconds!) faster by omitting the framework for a posix check, this patch makes it so that the framework is omitted by default, while still giving instructions for maintainers to re-enable it. It's been a while since we've used GNULIB_POSIXCHECK; see this email: https://lists.gnu.org/archive/html/coreutils/2012-03/msg00126.html Some of those failures are because we are intentionally avoiding specific gnulib modules (that is, we have chosen not to use things like fprintf-posix), but until we work with gnulib to avoid particular warnings, wiring up an automatic GNULIB_POSIXCHECK to happen during 'make my-distcheck' is not feasible. * configure.ac (gl_ASSERT_NO_GNULIB_POSIXCHECK): Conditionally define, according to whether $GNULIB_POSIXCHECK is in environment. --- configure.ac | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/configure.ac b/configure.ac index 07597e68b0..5a4860e7ba 100644 --- a/configure.ac +++ b/configure.ac @@ -35,6 +35,20 @@ AC_CONFIG_HEADERS([lib/config.h:lib/config.hin]) AM_INIT_AUTOMAKE([1.11.1 no-dist-gzip dist-xz color-tests parallel-tests]) AM_SILENT_RULES([yes]) # make --enable-silent-rules the default. +dnl POSIXCHECK is worthwhile for maintainers, but adds several seconds +dnl (more than 10% execution time) to ./configure, with no benefit for +dnl most users.
