Issues cross-compiling with MinGW

[NoName57]

I am having similar issues with what was going on with is post: #33 (comment)

The solution that worked for that poster is not working for me in this case by adding the {.passl: "-lz".} option to the libzip.nim file. I am simply just trying to compile a test of zip/zipfiles. The error output is below.

I was also having issues before this where it was unable to find zlib.h during compilation so I put zlib.h with ~/.nimble/pkgs/zip-0.3.1/zip/private/libzip_all.c in the same directory and changed the #include <zlib.h> to #include "zlib.h" because it wasn't finding it in /usr/include even when I compiled with --cincludes:/usr/include. So after I made that change it was able to find zlib.h and now I am getting the error above with the undefined references.

Anybody know why this is or what I could do to work around it?

I am running Nim Compiler ver 1.6.4 and the latest Zip which is pretty old. Are there any other more recent options for zipping up files?

Thanks.

Using Zippy (https://github.com/guzba/zippy) would probably be the best option for zipping files in nim atm. Even when I could get it to build, through the use of a windows vm, #45 made it pointless.
