How to test out wines WoW64?

[Dean Greer]

Hi everyone,

Since there now seems to be support within winex11.drv and winemac.drv what
patches are now required to make use of the WoW64 work?

I'd like to have this enabled within the macOS packages as soon as possible
even if that means possibly carrying some patches locally for a while,
ideally having a way to build the contents of i386-windows without needing
to build i386-unix.

You may use a branch that I use for testing [1]. It breaks printers 
support even for pure 64-bit applications, so we need a solution for 
that before we can upstream most of those patches.

In addition to above, Vulkan and OpenGL are not supported yet. We also 
don't have build system support for WoW64 builds. I just use full 32-bit 
build and simply not use unix libs in runtime for now, but we will want 
to change that.

Overall, it would be indeed nice to have people try it and I would be 
interested in feedback, but it doesn't feel ready for packages for 
regular users. Hopefully we will get there soon...

I’ll take a look thanks.

Not having Vulkan shouldn’t be much of an issue for macOS, but no OpenGL….

Makes sense I’d assumed that would be the case for the moment and wouldn’t
be too difficult to deal with on even a pure 64Bit version of macOS.

Agreed without OpenGL support this currently won’t be for regular users.

Hi Jacek,

I've gotten this built but it's not generating the wow64 slice of wow,
installed everything into the default location of /usr/local
> 0134:err:wow:load_32bit_module failed to load dll c0000034

After manually moving everything into place I'm getting the following
errors when attempting to launch anything that's 32Bit
> 0248:err:virtual:virtual_setup_exception stack overflow 1520 bytes in

thread 0248 addr 0x170030c10 stack 0x6d0a10 (0x6d0000-0x6d1000-0x7cfd20)

The same system built and runs a CX22 source build using the custom
llvm/clang-8 without issues (need to skip relocation)
