Reading Compiler Errors

Decode Zig's precise error messages.

Errors Are Your Allies

Zig's compiler errors are precise and friendly. Instead of fearing them, learn to read them; they usually point straight at the fix.

The Error Format

A Zig error starts with the file, line, and column, then the message. That location tells you exactly where to look first.

main.zig:3:5: error: unused local variable 'x'
