How to build 32x windows dll with mingw-w64

[wmcbrine]

When I installed mingw-w64, I installed a 32-bit version (i686-8.1.0-posix-dwarf-rt_v6-rev0), alongside a 64-bit version (x86_64-8.1.0-posix-seh-rt_v6-rev0). Each of these builds it natively, with no extra flags needed. I haven't really explored cross-compiling it.

I have explored cross-compiling. In fact, I rarely do Windows builds any other way. The Makefile from my fork will work with William's branch. For cross-compiling, you need to add either _w32=1 or _w64=1 to get the suitable prefix.
It essentially does what you describe (adding prefixes to CC, LINK, LIBEXE, and WINDRES). Maybe you missed one?

Ok so I took forever to fix it, I felt bad about leaving it open but I didn't want to close it without resolving the issue.

I made manual changes to the values to now be

CC = i686-w64-mingw32-gcc AR = i686-w64-mingw32-gcc-ar STRIP = strip LINK = i686-w64-mingw32-gcc WINDRES = C:\mingw-w64\i686-8.1.0-win32-sjlj-rt_v6-rev0\mingw32\bin\windres

and it seems to work.

I reinstalled mingw both 64 and i686 and also realized I had been using the wrong make, instead of mingw32=make.
I fixed those but mingw32-make was still calling the wrong gcc so I added both to path and referenced the i686 specific one.
Now it seems to build fine.

Thanks for listening and trying to help, and sorry I took so long to finish.
