However, --as-needed seems to cause libintl NOT to be taken in the +bad case, causing the undefined references to libintl_gettext. + +This patch changes the configure script so that the gettext check does not +use additional libraries such as libelf. The test program is linked either +with nothing, or with libintl alone. This will cause libintl to +be added explicitly to LIBS, when needed. + +[1] http://autobuild.buildroot.net/results/21b5a910e6a27fa1cb12d0002ffed7e6ed9d6c83/ +[2] http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2012-November/243930.html +[3] http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2012-May/234184.html + + +Signed-off-by: Thomas De Schampheleire +Upstream-status: accepted (http://article.gmane.org/gmane.editors.vim.devel/43528) + +--- + src/auto/configure | 11 ++++++----- + src/configure.in | 13 +++++++++---- + 2 files changed, 15 insertions(+), 9 deletions(-) + +diff --git a/src/auto/configure b/src/auto/configure +--- a/src/auto/configure ++++ b/src/auto/configure +@@ -12271,6 +12271,8 @@ fi + if test -f po/Makefile; then + have_gettext="no" + if test -n "$MSGFMT"; then ++ olibs=$LIBS ++ LIBS="" + cat confdefs.h - <<_ACEOF >conftest.$ac_ext + /* end confdefs.h. */ + #include +@@ -12284,10 +12286,9 @@ gettext("Test"); + _ACEOF + if ac_fn_c_try_link "$LINENO"; then : + { $as_echo "$as_me:${as_lineno-$LINENO}: result: gettext() works" >&5 +-$as_echo "gettext() works" >&6; }; have_gettext="yes" +-else +- olibs=$LIBS +- LIBS="$LIBS -lintl" ++$as_echo "gettext() works" >&6; }; have_gettext="yes"; LIBS=$olibs; ++else ++ LIBS="-lintl" + cat confdefs.h - <<_ACEOF >conftest.$ac_ext + /* end confdefs.h. */ + #include +@@ -12301,7 +12302,7 @@ gettext("Test"); + _ACEOF + if ac_fn_c_try_link "$LINENO"; then : + { $as_echo "$as_me:${as_lineno-$LINENO}: result: gettext() works with -lintl" >&5 +-$as_echo "gettext() works with -lintl" >&6; }; have_gettext="yes" ++$as_echo "gettext() works with -lintl" >&6; }; have_gettext="yes"; LIBS="$olibs -lintl"; + else + { $as_echo "$as_me:${as_lineno-$LINENO}: result: gettext() doesn't work" >&5 + $as_echo "gettext() doesn't work" >&6; }; +diff --git a/src/configure.in b/src/configure.in +--- a/src/configure.in ++++ b/src/configure.in +@@ -3484,6 +3484,9 @@ if test "$MANDEF" = "man -s"; then + fi + + dnl Check if gettext() is working and if it needs -lintl ++dnl We take care to base this on an empty LIBS: on some systems libelf would be ++dnl in LIBS and implicitly take along libintl.
