I've used PAR in the past (on Linux). Why are you suggesting to use PAR? Is it better or more widely used than LibZip?

Because , why LibZip?

LibZip never saw much use, GMPASSOS has been gone for ten years, and even ten years ago PAR was a more active better maintained project

last release of LibZip was 11 years ago ... in all that time no bur reports rt://LibZip

Even in 2003, the "heyday" of LibZip, floppy drives were dead ... and WIN64 was rare

PAR is still maintained and still compiles and produces executable

If PAR isn't to your liking there is always citrusperl( createdistribution/createexecutable ) or cavapackager or just plain portable strawberryperl

There is even , in a similar spirit as LiBZip, App::staticperl - perl, libc, 100 modules, all in one standalone 500kb file, but look at the testers matrix :)

update: Now I've had a chance to look at it, edit LibZip-0.06\myldr\Makefile.PL and add  $res = ''; somewhere before  open OUT
