cross compiling with mingw on linux to windows fails

Created by: vrecan

I am currently cross compiling zmq and sodium without issue. I wanted to start using goczmq and to do that I need to pull in czmq. Here is my script so far for compiling:

PREFIX=x86_64-w64-mingw32
CFLAGS="-DLIBCZMQ_EXPORTS -D__USE_MINGW_ANSI_STDIO"
cd $name-$version; make clean;./autogen;mingw64-configure configure --host=$PREFIX; mingw64-make; make install DESTDIR=$installDir

This is the error I am getting.

The zeromq and sodium builds don't require the cflags or the --host but I was reading other issues and people mentioned that they fixed mingw builds for them.

Any help would be greatly appreciated!
