Zlib should behave identically on both architectures, as long as you're passing it the same stream of bytes. In what way does it choke? Are you passing an appropriate value as the initial value of bufferLength? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
