Symbolic links in libzip

I'm using libzip in a c++ application for Linux that will need to be able to zip/unzip directories containing symbolic links. I want to add the link itself without following it. Reading out the link with readlink() and adding it to the zip archive results in a nonsense standard file when unzipped with unzip.

Solution does not need to be portable, it will only be used under Linux. The linux zip command has a --symlinks flags so the zip standard should support it. System calls are not really an option, the number of files is quite large and this makes the application extremely slow.

Is it possible to add symlinks with libzip, and how?

Thanks, Sander

  • Based on documentation: no

    According to its webpage, libzip is based on zlib. The zip program used in Linux, etc, is info-zip, which does not use zlib, but is self-contained (and contains features not in zlib).
