Module: ngircd.git Branch: master Commit: 0f85c4c6a70a71c935af9c28e2c469ea4b66220a URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=0f85c4c6a... Author: Alexander Barton <alex@barton.de> Date: Fri Jan 17 16:10:34 2014 +0100 Add libwrap at the end of the configure run If libwrap becomes added earlier, other tests may fail because of not all external variables required by libwrap are available when linking: for example allow_severity and deny_severity. This patch adds generic support for the LDFLAGS_END and LIBS_END variables (CFLAGS_END has been implemented already). Problem spotted on OpenBSD. --- configure.ng | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/configure.ng b/configure.ng index 0b0a658..7d22090 100644 --- a/configure.ng +++ b/configure.ng @@ -466,7 +466,9 @@ AC_ARG_WITH(tcp-wrappers, LDFLAGS="-L$withval/lib $LDFLAGS" fi AC_MSG_CHECKING(for hosts_access) + saved_LIBS="$LIBS" LIBS="-lwrap $LIBS" + LIBS_END="-lwrap $LIBS_END" AC_LINK_IFELSE([AC_LANG_PROGRAM([[ #include <tcpd.h> int allow_severity = 0; @@ -481,6 +483,7 @@ int deny_severity = 0; AC_MSG_RESULT(no) AC_MSG_ERROR([Can't enable TCP wrappers!]) ]) + LIBS="$saved_LIBS" fi ] ) @@ -636,9 +639,12 @@ AC_DEFINE_UNQUOTED(HOST_CPU, "$host_cpu" ) AC_DEFINE_UNQUOTED(HOST_VENDOR, "$host_vendor" ) AC_DEFINE_UNQUOTED(HOST_OS, "$host_os" ) -# Add additional CFLAGS, eventually specified on the command line, but after -# running this configure script.
