dnl @synopsis AX_PATH_BDB([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND]) dnl dnl This macro finds the latest version of Berkeley DB on the system, dnl and ensures that the header file and library versions match. 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 @version $Id: ax_path_bdb.m4,v 1.1 2005/01/06 20:24:52 shadow 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.
