Hi, I've autoconfiscated a project that link against libresolv and libtpthread, and optionally against ssl, mysqlclient and pq. I am working on Fedora 13 (i686). I've found a macro AX_EXT_HAVE_LIB (http://www.gnu.org/software/autoconf-archive/ax_ext_have_lib.html) that "is identical to AC_SEARCH_LIBS with the exception that will add -L<directory> when looking, and use a different variable for each directory. " It seems great for me! The problem is that at the end only take the last library found, in my case "pq". It seems that macro override the earlier value of "LIBS" variable. I've examined the configure script but it's a bit tricky, you may read a snippet about the macro on http://pastebin.com/vHKYp0UR I've tried modifying macro, replacing the final LIBS="$new_libs" por LIBS="$new_libs $LIBS" which you may read on http://pastebin.com/DNCCfgnU But now LIBS ends as: '-lpq -lmysqlclient -lssl -lpthread -lresolv -lssl -lpthread -lresolv ' It seems harmless but it's too ugly, isn't it? Please could you help me to get the correct value of LIBS variable The autoconf is as follows: AC_PREREQ([2.59]) AC_INIT([UpTools],[8.5.3],[bugs-uptools@xxxxxxxxxxx],[UpTools]) AM_INIT_AUTOMAKE([foreign -Wall -Werror]) LT_PREREQ([2.2]) LT_INIT([dlopen]) AC_CONFIG_MACRO_DIR([m4]) AC_CONFIG_SRCDIR([UpConf.cc]) AC_CONFIG_HEADERS([config.h]) AC_PREFIX_DEFAULT(/usr) AC_PROG_CXX AX_EXT_HAVE_LIB([/lib64 /lib /usr/lib64 /usr/lib64 /usr/lib /usr/local/lib64 /usr/local/lib],resolv,inet_net_pton) AS_ECHO($LIBS) AX_EXT_HAVE_LIB([/lib64 /lib /usr/lib64 /usr/lib64 /usr/lib /usr/local/lib64 /usr/local/lib],pthread,pthread_create) AC_ARG_WITH([ssl], [AS_HELP_STRING([--with-ssl], [enable support for ssl @<:@default=check@:>@])], [], [with_ssl=check]) AS_IF([test "x$with_ssl" != xno],[AX_EXT_HAVE_LIB(/lib64 /lib /usr/lib64 /usr/lib /usr/local/lib64 /usr/local/lib /usr/local/lib64/ssl /usr/lib/ssl , ssl, SSL_library_init)], [if test "x$with_ssl" != xcheck -a "x$ext_lib_found" = xno then AC_MSG_FAILURE([ssl test failed (--without-ssl to disable)]) fi ]) if test x"$ext_lib_found" = xyes then found_ssl=yes fi AC_ARG_WITH([mysql], [AS_HELP_STRING([--with-mysql], [enable support for mysql @<:@default=check@:>@])], [], [with_mysql=check]) AS_IF([test "x$with_mysql" != xno],[AX_EXT_HAVE_LIB(/lib64 /lib /usr/lib64 /usr/lib /usr/local/lib64 /usr/local/lib /usr/local/lib64/mysql /usr/lib/mysql , mysqlclient, mysql_close)], [if test "x$with_mysql" != xcheck -a "x$ext_lib_found" = xno then AC_MSG_FAILURE([mysql test failed (--without-mysql to disable)]) fi ]) if test x"$ext_lib_found" = xyes then found_mysql=yes fi AC_ARG_WITH([postgresql], [AS_HELP_STRING([--with-postgresql], [enable support for mysql @<:@default=check@:>@])], [], [with_postgresql=check]) AS_IF([test "x$with_postgresql" != xno],[AX_EXT_HAVE_LIB(/lib64 /lib /usr/lib64 /usr/lib /usr/local/lib64 /usr/local/lib /usr/local/lib64/postgresql /usr/lib/postgresql , pq, PQfinish)], [if test "x$with_postgresql" != xcheck -a "x$ext_lib_found" = xno then AC_MSG_FAILURE([postgresql test failed (--without-postgresql to disable)]) fi ]) if test x"$ext_lib_found" = xyes then found_postgresql=yes fi AC_HEADER_RESOLV if test "x${found_ssl}" = xyes then AC_CHECK_HEADERS([openssl/ssl.h yassl/ssl.h], [break]) if test x"$ac_cv_header_openssl_ssl_h" != xyes -a x"$ac_cv_header_yassl_ssl_h" != xyes then AC_MSG_FAILURE([ssl headers not found or not usable]) else ssl=true fi else ssl=false fi if test "x$want_mysql" != xno -a "x$found_mysql" != xno then AC_CHECK_HEADERS([mysql/mysql.h mysql.h], [break]) if test x"$ac_cv_header_mysql_mysql_h" != xyes -a x"$ac_cv_header_mysql_h" != xyes then AC_MSG_FAILURE([MySQL headers not found or not usable]) else mysql=true fi else mysql=false fi if test x"${found_pq}" = xyes then AC_CHECK_HEADERS([postgresql/libpq-fe.h libpq-fe.h], [break]) if test x"$ac_cv_header_postgresql_libpq_fe_h" != xyes -a x"$ac_cv_header_libpq_fe_h" != xyes then AC_MSG_FAILURE([PostgreSQL headers not found or not usable]) else postgresql=true fi else postgresql=false fi AM_CONDITIONAL([ssl], [test x$ssl = xtrue]) AM_CONDITIONAL([mysql], [test x$mysql = xtrue]) AM_CONDITIONAL([postgresql], [test x$postgresql = xtrue]) if test x"$ssl" = xfalse then ss="No. You may enable with --enable-ssl" else ss="Yes" fi if test x"$mysql" != xtrue then ms="No. You may enable with --with-mysql" else ms="Yes" fi if test x"$postgresql" = xfalse then pq="No. You may enable with --with-postgresql" else pq="Yes" fi AC_CHECK_HEADERS([arpa/inet.h fcntl.h netdb.h netinet/in.h stdlib.h string.h strings.h sys/ioctl.h sys/socket.h sys/time.h syslog.h unistd.h]) AC_HEADER_STDBOOL AC_C_INLINE AC_TYPE_SIZE_T AC_FUNC_MKTIME AC_CHECK_FUNCS([gethostbyname localtime_r memmove memset regcomp select socket strcasecmp strerror strncasecmp]) AC_CONFIG_FILES([Makefile]) AC_OUTPUT echo \ "------------------------------------------------- Congratulations!
