I encountered a very strange problem while using it.
I have no problem using javasript packages and can parse them normally. However, when using cpp or c, errors will be reported.

He seems to be a problem with cgo, but JavaScript packages are also used. Why can cgo succeed.
!!!!!!!

this is my code:

package main

import (
    "context"
    "fmt"

    sitter "github.com/smacker/go-tree-sitter"
    cpp "github.com/smacker/go-tree-sitter/javascript"
    // cpp "github.com/smacker/go-tree-sitter/cpp"
)

func main() {
    parser := sitter.NewParser()
    parser.SetLanguage(cpp.GetLanguage())

    // sourceCode := `
    // int main(int argc, char *argv[])
    // {
    //  msfn();
    //  for (int i = 0; i < argc; i++)
    //  {
    //      std::cout << "  ====" << argv[i] << std::endl;
    //  }
    //  CustomNameSpace::fn1(1);
    //  return 0;
    // }
    // `
    sourceCode := `function fn1(){ console.log("hello, world") }`
    tree, _ := parser.ParseCtx(context.Background(), nil, []byte(sourceCode))
    n := tree.RootNode()

    fmt.Println(n)
    child := n.NamedChild(0)
    fmt.Println(child.Type())
    fmt.Println(child.StartByte())
    fmt.Println(child.EndByte())
}
