Seems to be similar to #16932

What did you do?

package main

import (
	"database/sql"
	"fmt"

	_ "github.com/mattn/go-sqlite3"
)

func main() {
	db, err := sql.Open("sqlite3", "./foo.db")
	if err != nil {
		panic(err)
	}

	fmt.Printf("%v+", db)
}
  1. Installed clang via the Visual Studio 2022 installer
  2. Opened a VS 2022 Developer Powershell
  3. $env:CGO_ENABLED=1
  4. $env:CC="clang"
  5. go build

(I also tried $env:CGO_CFLAGS="-fuse-ld=lld" and $env:CFLAGS="-fuse-ld=lld" with the same result)

What did you expect to see?

Program built successfully.

What did you see instead?

Unfortunately this looks like a dupe of #17014

It is. Direct use of clang is not supported yet, although that can bridge this gap, i.e. https://github.com/mstorsjo/llvm-mingw. In fact that toolchain is being used by the windows/arm64 builders right now.

@qmuntal is clang/msvc support planned at all?

I'll love that to happen. #17014 is labeled as help wanted and needs fix, so Go will support clang on Windows when someone has the time to implement it.
