If +dnl MINIMUM-VERSION is specified, it will ensure that the library +dnl found is at least that version. +dnl +dnl It determines the name of the library as well as the path to the +dnl header file and library. It will check both the default environment +dnl as well as the default Berkeley DB install location. When found, it +dnl sets BDB_LIBS, BDB_CPPFLAGS, and BDB_LDFLAGS to the necessary values +dnl to add to LIBS, CPPFLAGS, and LDFLAGS, as well as setting BDB_VERSION +dnl to the version found. HAVE_DB_H is defined also. +dnl +dnl The option --with-bdb-dir=DIR can be used to specify a specific +dnl Berkeley DB installation to use. +dnl +dnl An example of it's use is: +dnl AX_PATH_BDB([3],[ +dnl LIBS="$BDB_LIBS $LIBS" +dnl LDFLAGS="$BDB_LDFLAGS $LDFLAGS" +dnl CPPFLAGS="$CPPFLAGS $BDB_CPPFLAGS" +dnl ]) +dnl which will locate the latest version of Berkeley DB on the system, +dnl and ensure that it is version 3.0 or higher. +dnl +dnl Details: This macro does not use either AC_CHECK_HEADERS or +dnl AC_CHECK_LIB because, first, the functions inside the library are +dnl sometimes renamed to contain a version code that is only available +dnl from the db.h on the system, and second, because it is common to +dnl have multiple db.h and libdb files on a system it is important to +dnl make sure the ones being used correspond to the same version. +dnl Additionally, there are many different possible names for libdb +dnl when installed by an OS distribution, and these need to be checked +dnl if db.h does not correspond to libdb. +dnl +dnl When cross compiling, only header versions are verified since it +dnl would be difficult to check the library version. Additionally +dnl the default Berkeley DB installation locations /usr/local/BerkeleyDB* +dnl are not searched for higher versions of the library. +dnl +dnl The format for the list of library names to search came from the +dnl Cyrus IMAP distribution, although they are generated dynamically +dnl here, and only for the version found in db.h. +dnl +dnl The macro AX_COMPARE_VERSION is required to use this macro, and +dnl should be available from the Autoconf Macro Archive. +dnl +dnl The author would like to acknowledge the generous and valuable feedback +dnl from Guido Draheim, without which this macro would be far less robust, +dnl and have poor and inconsistent cross compilation support. +dnl +dnl Changes: +dnl 1/5/05 applied patch from Rafa Rzepecki to eliminate compiler +dnl warning about unused variable, argv +dnl +dnl @version $Id: ax_path_bdb.m4,v 1.3 2005/01/20 00:15:41 guidod Exp $ +dnl @author Tim Toolan <toolan@ele.uri.edu> +dnl + +dnl ######################################################################### +AC_DEFUN([AX_PATH_BDB], [ + dnl # Used to indicate success or failure of this function. + ax_path_bdb_ok=no + + # Add --with-bdb-dir option to configure. + AC_ARG_WITH([bdb-dir], + [AC_HELP_STRING([--with-bdb-dir=DIR], + [Berkeley DB installation directory])]) + + # Check if --with-bdb-dir was specified. + if test "x$with_bdb_dir" = "x" ; then + # No option specified, so just search the system. + AX_PATH_BDB_NO_OPTIONS([$1], [HIGHEST], [ + ax_path_bdb_ok=yes + ]) + else + # Set --with-bdb-dir option. + ax_path_bdb_INC="$with_bdb_dir/include" + ax_path_bdb_LIB="$with_bdb_dir/lib" + + dnl # Save previous environment, and modify with new stuff. + ax_path_bdb_save_CPPFLAGS="$CPPFLAGS" + CPPFLAGS="-I$ax_path_bdb_INC $CPPFLAGS" + + ax_path_bdb_save_LDFLAGS=$LDFLAGS + LDFLAGS="-L$ax_path_bdb_LIB $LDFLAGS" + + # Check for specific header file db.h + AC_MSG_CHECKING([db.h presence in $ax_path_bdb_INC]) + if test -f "$ax_path_bdb_INC/db.h" ; then + AC_MSG_RESULT([yes]) + # Check for library + AX_PATH_BDB_NO_OPTIONS([$1], [ENVONLY], [ + ax_path_bdb_ok=yes + BDB_CPPFLAGS="-I$ax_path_bdb_INC" + BDB_LDFLAGS="-L$ax_path_bdb_LIB" + ]) + else + AC_MSG_RESULT([no]) + AC_MSG_NOTICE([no usable Berkeley DB not found]) + fi + + dnl # Restore the environment. + CPPFLAGS="$ax_path_bdb_save_CPPFLAGS" + LDFLAGS="$ax_path_bdb_save_LDFLAGS" + + fi + + dnl # Execute ACTION-IF-FOUND / ACTION-IF-NOT-FOUND. + if test "$ax_path_bdb_ok" = "yes" ; then + m4_ifvaln([$2],[$2],[:])dnl + m4_ifvaln([$3],[else $3])dnl + fi + +]) dnl AX_PATH_BDB + +dnl ######################################################################### +dnl Check for berkeley DB of at least MINIMUM-VERSION on system. +dnl +dnl The OPTION argument determines how the checks occur, and can be one of: +dnl +dnl HIGHEST - Check both the environment and the default installation +dnl directories for Berkeley DB and choose the version that +dnl is highest.
