windows build with zig-bootstrap generated binaries fails

[neeraj9]

Zig Version

0.11.0-dev.995+7350f0d9b

Steps to Reproduce and Observed Behavior

git clone https://github.com/ziglang/zig-bootstrap
cd zig-bootstrap
build.bat x86_64-windows-gnu baseline
cd ..
git clone https://github.com/ziglang/zig
cd zig
..\zig-bootstrap\out-win\zig-x86_64-windows-gnu-baseline\zig.exe build -p stage3 --search-prefix ..\zig-bootstrap\out-win\x86_64-windows-gnu-baseline --zig-lib-dir lib -Dstatic-llvm

Expected Behavior

Zig should build from binaries generated from zig-bootstrap, but I get the following error:

this is neither of the options from https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows

if using a zig from the website also fails then it will only be because master changed recently and the tarballs haven't finished updating yet. upstream change was made here 4f782d1

I built zig via zig-bootstrap. If the zig built with that cannot compile latest zig in this git repo then what will? Additionally, any pointers to debug the error will be of great help.
Isn't this command supposed to work irrespective of the platform?

..\zig-bootstrap\out-win\zig-x86_64-windows-gnu-baseline\zig.exe build -p stage3 --search-prefix ..\zig-bootstrap\out-win\x86_64-windows-gnu-baseline --zig-lib-dir lib -Dstatic-llvm

The first two errors are caused by #15803 but even if you fixed those you'd run into other issues since zig-bootstrap is ~1k commits behind master branch Zig. You need to either update the sources in zig-bootstrap to be able to build master branch Zig or just build Zig using this repo.

It is interesting that I tried to take the zig devkit zig+llvm+lld+clang-x86_64-windows-gnu-0.12.0-dev.2073+402fe565a.zip as per 1 and 2 and still the build failed.

The combination which worked was to use zig.exe from https://ziglang.org/builds/zig-windows-x86_64-0.12.0-dev.3304+bc5b09469.zip, while the llvm libraries from zig+llvm+lld+clang-x86_64-windows-gnu-0.12.0-dev.2073+402fe565a.zip and that successfully built zig version 0.12.0-dev.3291+17bad9f88.

It appears zig in this repo is very specific to zig and llvm library versions and break's if the versions dont match up correctly.
