[valve-exp-bleeding] wow64 mode #1070

Open gabriele2000 opened 11 months ago

gabriele2000 commented 11 months ago

I managed to compile a wow64 build using this profile, I'd like to know if it's possible to actually create a prefix using this mode, since there's nothing in "syswow64".

That reminds me of pre-wine.8.12 or something, where that folder would be empty

Wow64 is forcefully disabled on proton builds due to dependencies and a number of patches that are simply broken in wow64 mode, so unless you have modified the script to remove the safeguards, it's not actually a wow64 build.

Heh, I just added "wow64" on "disable 32-bit libs"

You gave me a cool idea.

How could I bypass the safeguards?

You'll need to comment out or delete lines 282 to 285 in wine-tkg-git/wine-tkg-scripts/prepare.sh.

That being said, it's not supposed to work. The wine 8.0 base used by Proton has incomplete wow64 support to begin with.

Let me guess: it's based on the stable wine version, since from 8.16 wow64 support has become a lot more working? (it removed the "empty syswow64 folder" bug)

Yeah, Valve's current Proton is based on 8.0 "stable" indeed. You can use proton-tkg to build upstream-based proton builds and _NOLIB32="wow64" is allowed in that case, but YMMV with tooling dependencies building (pretty much untested).

I have added basic handling of the wow64 file structure for proton. The main blockers will be external tooling like steam.exe/lsteamclient in 32-bit emulation, which will break. For pure 64-bit executables it should be okay though.
