Is wine32 really necessary?

Post by LMLM »

I've been dealing with a new installation of Linux, installed wine64 but haven't created a wine32 prefix yet. All the applications I run are old and 32bit. They all work. Is wine32 really necessary? Why?

It seems that some applications do not not run otherwise. If you see section "Shared WoW64" in https://gitlab.winehq.org/wine/wine/-/w ... lding-Wine, it says:


64-bit Wine built without 32-bit support will not be able to run ANY 32-bit applications, which most Windows binaries are. Even many 64-bit programs still include 32-bit components!


In my case, I need for some applications cuda support (cuda-z, gpu_caps_viewer, warpem, ...). In order to make this work, I'm using Sveinar's nvidia-libs. These is currently only working with the old WoW64, and does not work with the new "shared WoW64" approach.
