building external libraries for binary distributtion

hi all, i work on building my own external library that should be usable within php using the //dl(.) command. so i read it the docs about how to write extension but i felt somehow low left alone, cause the docs only just describes how to create extensions that are shipped with the source for being able to build a complete new php (and the code the documents contain isn't working either !!!). so what i'm looking for is a mechanism to built my extension on my local php installation (full sourc of everything available) and then just only send the library file (myext.so) to the customer, that itself just puts the lib somewhere to be loaded by php's //dl(.) command are there any other docs / recources available than those from the php-manual: en/zend.creating.php thanks in advance . cu joerg
