Hi, I've autoconfiscated an open source project. I don't using still automake, only I am using autoconf. So I've created an confugure.ac as follows: AC_PREREQ([2.65]) AC_INIT([UpTools],[8.4],[bugs-uptools@xxxxxxxxxx]) AM_INIT_AUTOMAKE([foreign -Wall -Werror dist-bzip2]) AC_CONFIG_SRCDIR([UpConf.cc]) AC_CONFIG_HEADERS([config.h]) AC_PROG_CXX AC_PROG_CC AC_LANG([C++]) AC_PROG_RANLIB AC_CHECK_LIB([ssl], [main],[SSL=-lssl],echo "Error: Required library ssl not found. Install openssl development package and try again" && exit 1 ) AC_CHECK_LIB([crypto], [main],[CRYPTO=-lcrypto],echo "Error: Required library crypto not found. Install openssl development package and try again" && exit 1) AC_CHECK_LIB([pq], [main],[PQ=-lpq],echo "Error: Required library pq not found. Install it and try again" && exit 1) AC_CHECK_LIB([pthread], [main],[PTHREAD=-lpthread],echo "Error: Required library pthread not found. Install it and try again" && exit 1) if test -e /usr/lib64/libresolv.a then "echo checking for /usr/lib64/libresolv.a..yes" else if test -e /usr/lib/libresolv.a then echo "checking for /usr/lib/libresolv.a..yes" else echo "It seems libresolv.a is missing. Install the package that provides it" && exit 1 fi fi AC_HEADER_RESOLV 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 EOF I've build that on Mandriva 2010.1 and it worked fine. It compiles with no problems. But it's failing to find mysql libraries on a Fedora 9 system even those libraries are installed: ls /usr/lib/mysql/ libdbug.a libmyisammrg.a libmysqlclient_r.so libmysqlclient.so libmystrings.a mysqlbug libheap.a libmysqlclient.a libmysqlclient_r.so.15 libmysqlclient.so.15 libmysys.a mysql_config libmyisam.a libmysqlclient_r.a libmysqlclient_r.so.15.0.0 libmysqlclient.so.15.0.0 libvio.a configure scripts complains: checking for mysql_get_parameters in -lmysqlclient... no Error: Required library mysqlclient not found. Install it and try again Is there somthing wrong with my configure.ac?
