portable zip library for C/C++ (not an application) [closed]
Solution 1:
Take a look at Libarchive. I spent a lot of time seeking for a cross-platform and LGPL licensed library with convenient interface. This the best of all I've seen. Very easy and powerful tool. Originally designed for Unix-like systems but there's also the Windows version.
Solution 2:
I've had great results with miniz: https://code.google.com/p/miniz/
For a simple compression of strings in c++, I also really like Timo Bingmann's solution.
