Tried compiling zig master from source using the lastest compiled zig version. Got a bunch of sub-compilation errors

[BurdujaAdrian]

Zig Version

0.14.0-dev.1021+fc2924080

Steps to Reproduce and Observed Behavior

1. Use zig-windows-x86_64-0.14.0-dev.1021+fc2924080

2. git clone https://github.com/ziglang/zig

3. cd zig

4. zig build run

Output:

Expected Behavior

Zig is successfully compiled from source

[ianprime0509]

Which commit of the Zig repository are you trying to build? The errors you're getting all look related to changes made in #20885, suggesting that you're trying to use Zig 0.14.0-dev.1021+fc2924080 (which came after that change) to compile a commit of Zig made before that change, which will not work due to the breaking change in the tokenizer.

More information on how to build Zig from source is available here: https://github.com/ziglang/zig/wiki/Building-Zig-From-Source

I also recommend that, for any difficulties building Zig from source for the first time, you reach out for help in one of the Zig communities since there will likely be follow-up questions during the process which would be better suited for one of the community spaces than the issue tracker.
