Subject: Re: C++ extension question
From: jay@php.net (Jay Smith)


I'm assuming "delete" isn't a function but the C++ operator delete. You're
probably #including the same file more than once, but I doubt it's in Zend. 

If all else fails, you can try passing "/FORCE" to the linker options and
it'll try to force the linkage. It might result in a broken binary, though.
