MAMEWorld Forums - MAMEUI & IV/Play - Error compiling mameui64 0.173

I've started with the base 173 source and was able to get the MAME and MAME64 executables compiled just fine.

then I downloaded the mameui173s.rar file from the mameui repository and extracted it on top of the source (like I've always done), then tried compiling with this make command:

make -j5 OSD=winui PTR64=1 STRIP_SYMBOLS=1

I don't see any error messages, but I do just see the compiler just stop:

Any ideas of what I may be missing?

Thanks.
