Would it be possible to provide the compiled php_runkit.dll? I'm having a hard time creating it myself, and I don't find it anywhere for downloading.
I also encountered issues when building the DLL but the following process worked for me.
THere's no plans to distribute precompiled DLLs for Windows?
Thanks @sonsinim, going by your description I managed to easily compile runkit for all current PHP versions. The worst part was waiting for VM to install everything needed :)
I uploaded my binaries for PHP 5.3, 5.4 and 5.5 at https://github.com/Crack/runkit-windows
