dnl SVN_LIB_BERKELEY_DB(major, minor, patch)
dnl
dnl Compare if the DB provided by APR-UTIL is no older than the
dnl version given by MAJOR, MINOR, and PATCH.
dnl
dnl If we find a useable version, set the shell variable
dnl `svn_lib_berkeley_db' to `yes'. Otherwise, set `svn_lib_berkeley_db'
dnl to `no'.
dnl
dnl This macro also checks for the `--with-berkeley-db=PATH' flag;
dnl if given, the macro will use the PATH specified, and the
dnl configuration script will die if it can't find the library. If
dnl the user gives the `--without-berkeley-db' flag, the entire
dnl search is skipped.
AC_DEFUN(SVN_LIB_BERKELEY_DB,
[
db_version=$1.$2.$3
dnl Process the `with-berkeley-db' switch. We set `status' to one
dnl of the following values:
dnl `required' --- the user specified that they did want to use
dnl Berkeley DB, so abort the configuration if we cannot find it.
dnl `try-link' --- See if APR-UTIL supplies the correct DB version;
dnl if it doesn't, just do not build the bdb based filesystem.
dnl `skip' --- Do not look for Berkeley DB, and do not build the
dnl bdb based filesystem.
dnl
dnl Finding it is defined as doing a runtime check against the db
dnl that is supplied by APR-UTIL.
dnl Assuming `status' is not `skip', we do a runtime check against the db
dnl that is supplied by APR-UTIL.
dnl
dnl Since APR-UTIL uses --with-berkeley-db as well, and we pass it
dnl through when APR-UTIL is in the tree, we also accept a place spec
dnl as argument, and handle that case specifically.
dnl
dnl A `place spec' is either:
dnl - a directory prefix P, indicating we should look for headers in
dnl P/include and libraries in P/lib, or
dnl - a string of the form `HEADER:LIB', indicating that we should look
dnl for headers in HEADER and libraries in LIB.

The Subversion Berkeley DB based filesystem library
requires Berkeley DB $db_version or newer. If you
specify `--without-berkeley-db', that library will
not be built. Otherwise, the configure script builds
that library if and only if APR-UTIL is linked
against a new enough version of Berkeley DB.
If and only if you are building APR-UTIL as part of
the Subversion build process, you may help APR-UTIL
to find the correct Berkeley DB installation by
passing a PATH to this option, to cause APR-UTIL to
look for the Berkeley DB header and library in
`PATH/include' and `PATH/lib'. If PATH is of the
form `HEADER:LIB', then search for header files in
HEADER, and the library in LIB. If you omit the
`=PATH' part completely, the configure script will
search for Berkeley DB in a number of standard
places.])],

dnl SVN_LIB_BERKELEY_DB_TRY(major, minor, patch)
dnl
dnl A subroutine of SVN_LIB_BERKELEY_DB.
dnl
dnl Check that a new-enough version of Berkeley DB is installed.
dnl "New enough" means no older than the version given by MAJOR,
dnl MINOR, and PATCH. The result of the test is not cached; no
dnl messages are printed.
dnl
dnl Set the shell variable `svn_have_berkeley_db' to `yes' if we found
dnl an appropriate version via APR-UTIL, or `no' otherwise.
dnl
dnl This macro uses the Berkeley DB library function `db_version' to
dnl find the version. If the library linked to APR-UTIL doesn't have this
dnl function, then this macro assumes it is too old.
dnl NOTE: This is pretty messed up. It seems that the FreeBSD port of
dnl Berkeley DB 4 puts the header file in /usr/local/include/db4, but the
dnl database library in /usr/local/lib, as libdb4.[a|so]. There is no
dnl /usr/local/include/db.h. So if you check for /usr/local first, you'll
dnl get the old header file from /usr/include, and the new library from
dnl /usr/local/lib. Disaster. Thus this test compares the version constants
dnl in the db.h header with the ones returned by db_version().
