I have this graphics program in C++ working with 32 bit MinGW and Qt Libs.

Now I'd like to move it up a notch to the 64 bit world.

I'm developing it in Eclipse Neon-3 so I'm looking for 64 bit : g++, Mingw-make, gdb and the Qt Libs

I have lots of candidates downloaded from the web.

when I do gdb --version or mingw32-make --version at the cmd.exe window I get :

configured as

i686-posix-dwarf-rev0

i686-w64-mingw32

x86_64-w64-ming32

i686-pc-mingw32

my laptop in amd64 hardware with 64bit windows 10, but how do I translate these "configured as" descriptions??

32 bit or 64 bit????
