What did you do?
./v -g -o vdbg cmd/v && ./vdbg cmd/tools/vshare.v

module main

import net.http
import os
import clipboard
import json

struct Response {
	hash  string
	error string
}

fn main() {
	mut cb := clipboard.new()

	if os.args.len < 3 {
		eprintln('Please provide a file')
		exit(1)
	}

	if os.file_ext(os.args[2]) != '.v' {
		eprintln('Must be a V source file.')
		exit(1)
	}

	if !os.is_file(os.args[2]) {
		eprintln('File not found.')
		exit(1)
	}

	to_send := os.args[2]

	content := os.read_file(to_send) or {
		eprintln(err)
		exit(1)
	}

	share := http.post_form('https://play.vlang.io/share', {
		'code': content
	})!

	response := json.decode(Response, share.body)!
	url := 'https://play.vlang.io/p/${response.hash}'

	cb.copy(url)
	println(url)
	println('Copied URL to clipboard.')
}

What did you expect to see?

A passing test when running v build-tools.
I have X11 installed (even though I run Wayland), so the linker shouldn't be failing to find the library.

What did you see instead?

================== C compilation error (from clang-18): ==============
cc: 48 warnings generated.
cc: ld.lld: error: unable to find library -lX11
cc: clang-18: error: linker command failed with exit code 1 (use -v to see invocation)
... (the original output was 147 lines long, and was truncated to 3 lines)
======================================================================
(You can pass `-cg`, or `-show-c-output` as well, to print all the C error messages).
builder error: 
==================
C error found. It should never happen, when compiling pure V code.
This is a V compiler bug, please report it using `v bug file.v`,
or goto https://github.com/vlang/v/issues/new/choose .
