The configure script is unable to find the db4 in the system, because it isn't
taking into account #defines such as the following in /usr/include/db.h:

#define db_create db_create_4001

The library does not contain unversioned symbols and therefore the configure
script needs to #include the db.h to be able to make proper checks for the
versioned symbols.

Replacing the AC_CHECK_LIB with somewhat similar AC_TRY_LINK should do the
trick.  See the following patch (I've only tried it with db4.1, I don't know if
the function signature is the same for older versions, but I'd think so.)

First thanks for directing me to an error.

Second please keep my code inside it's there for a reason
and then make up a new patch. But i'm on it.

If you are using PHP-4.3.4 with db-4.1.25 make sure that you have db-4.1.25 (Berkeley DB) compiled with "LIBSO_LIBS= -lpthread" in Makefile (db-4.1.25/build_unix/Makefile). Se more at http://www.sleepycat.com/docs/ref/build_unix/notes.html in section 3.

not fixed in CVS!
problem: incorrect order of c src and libs.
you must prepend LDFLAGS and LIBS, seperate LIBS from LDFLAGS.

$ gcc -o conftest -g -O2  -L/usr/lib -ldb-4.2  conftest.c -lresolv -lm
/tmp/ccozwee7.o(.text+0x29): In function `main':
/usr/src/apache-php/php-4.3.9/conftest.c:7: undefined reference to `_db_create'

rurban@reini /usr/src/apache-php/php-4.3.9
$ gcc -o conftest -g -O2  conftest.c -L/usr/lib -ldb-4.2 -lresolv -lm

(the same goes for ext/ldap/config.m4)
