dnl These are the Cyrus Berkeley DB macros. In an ideal world these would be
dnl identical to the above.
dnl They are here so that they can be shared between Cyrus IMAPd
dnl and Cyrus SASL with relative ease.
dnl The big difference between this and the ones above is that we don't assume
dnl that we know the name of the library, and we try a lot of permutations
dnl instead. We also assume that DB4 is acceptable.
dnl When we're done, there will be a BDB_LIBADD and a BDB_INCADD which should
dnl be used when necessary. We should probably be smarter about our RPATH
dnl handling.
dnl Call these with XASTIR_BERKELEY_DB_CHK.
dnl We will also set $dblib to "berkeley" if we are successful, "no" otherwise.
dnl this is unbelievably painful due to confusion over what db-3 should be
dnl named and where the db-3 header file is located. arg.

# We need to add the following algorithm here:
#
# Find the db.h file, grep for DB_VERSION_MAJOR and
# DB_VERSION_MINOR. In my case I get this:
#
# #define DB_VERSION_MAJOR 4
# #define DB_VERSION_MINOR 1
#
# Find the libdb.so file that Xastir would link to. Find the
# version via the target of the symlink? In my case I have
# this:
#
# > ls -al libdb.so
# lrwxrwxrwx 1 root root 12 2004-01-07 11:29 libdb.so -> libdb-4.
#
# Compare the major/minor numbers. If they match, we're good to
# go. If not, don't compile in libdb support. Perhaps we could
# just run ldd on the test code to get the version number of the
# linked library instead?
#
# Another possible way to do it would be to create test code and
# compile/run it which would open/write/read/close/delete a
# database. That should help to prove that Xastir would run ok if
# the library were used.
