And now try the same on windows :) It is also possible to use 2k5/8 binaries with VC6 binaries but that's a call for troubles. It is often possible to do many things (even different architecture support) on unix/linux and sometimes with windows. But we don't support that, that's what I meant with "you can't". I should have said: "You can but it is not supported" :) Cheers, -- Pierre http://blog.thepimp.net | http://www.libgd.org
