Re: luasocket unstable IPV6_V6ONLY undefined in mingw

I remember running into some similar issues (although I didn't use CMake); since I wanted to compile with mingw for Lua52, I patched luasocket to add inet_pton and inet_ntop support on Windows. I just pushed it to github as it was sitting locally for couple of months: https://github.com/pkulchenko/luasocket/tree/lua52-mingw

I also added build-mingw.sh script that compiles both luasocket DLLs. Just make Lua52 available or tweak the path in the script to point to your Lua52 sources and see if this works for you.

Not sure why IPV6_V6ONLY should be 27, I compile it with the following parameters:

-Wl,-s -O2 -shared -D LUA_COMPAT_MODULE -D IPV6_V6ONLY=1 -D WINVER=0x0501 -s -I src -I $LUA -L $LUA
