Free C/C++ based zip/zip64 library?

Question

After having false starts with poco's zip and minizip (both have issues, minizip can't decompress files larger than 2gb and poco zip corrupts any zip file larger than 2 gigs it compresses) I was wondering if there was anything else left?

So any suggestions for a C++ archive library that can handle zip AND zip64?

Answer 1

7-zip handles both, as far as I could tell from a quick glance at their source code. It's also LGPL, which should allow its use in a closed source app.
