I'm following this tutorial to compile PHP on windows.
I'm now at the last steps, but for some reason I get a whole lot of errors like
WARNING: zlib support can't be enabled, zlib is missing
Despite the fact that zlib is definitely present under ext/ in the PHP sources I use.
Where do I need to put that folder so the compiler can "see" it?
The zlib extension source code might indeed be in the ext/ folder, but are you sure that your compiler knows where the dependancies (such as the zlib library) are?
Have you seen http://wiki.php.net/internals/windows/libs ?
There is a download provided by PHP at http://windows.php.net/downloads/php-sdk/ where you can get binary versions of all the PHP dependancies for Windows (which will save a lot of time).
What version of VC++ do you have installed?
