Re: [Mingw-w64-public] i686-w64-mingw32 and x86_64-w64-mingw32 coexisting

Hello Chris,

Yes, it is possible to have both runtimes within one toolchain. You
need to build it with multilib support. The directory /mingw/lib
(/<default-target>/lib) is the library folder for the default target.
This means, if you build for example a x64 defaulted toolchain, that
lib is for 64-bit libraries and objects. As sibling to lib a link to
it, named "lib64", has to exist. Additionally the folder "lib32" has
to be generated as sibling folder to "lib" for the 32-bit libraries
and objects.
The headers are shared between both versions.

See for this on our SF Wiki the guide for multilib support.

Cheers,
Kai
