Re: Link error with static version of zlib?




Hello Steven,

    Thank you very much for taking the time to reply to my question!

I downloaded
http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-zlib-1.2.8-9-any.pkg.tar.xz

I then copied the file libminizip.a contained within to
/usr/x86_64-w64-mingw32/sys-root/mingw/lib/
I also copied the file libz.a contained within to
/usr/x86_64-w64-mingw32/sys-root/mingw/lib/
making sure to rename the original file to libz.a.old so I can undo,
if necessary.

The rationale for doing this is that those two files are the only two
dependencies outside of the Windows system dlls the project uses.

However, at the link, there was still an error:

/usr/x86_64-w64-mingw32/sys-root/mingw/lib/../lib/libminizip.a(unzip.o):(.text+0x13b9):

I've tried linking the thread library, but it does not seem to make a
difference.

I'm not sure how to proceed.
