I am using cygwin, zlib, and zzip.. and zlib compiles without a problem, so does stock php(CVS). But zzip wouldnt (0.10.27 or 0.10.53) wouldnt compile at first (It gave me errors about redefined types). I modified the file causing the problem. And it compiled and installed (set the prefix to /usr). anyway. PHP can find the library now.. but it says that it cant find zzip_open in the library, and then tells me I need a version >= 0.10.6.. I really need zip support in my windows based PHP server.
