Была поставлена задача:
1) Написать шаред либу на c++
2) Прикрутить эту библиотеку к node.js так, чтобы можно было передавать жавоскриптовые коллбеки внутрь этой библиотеки.
С первым пунктом справился, а со вторым пунктом возникли проблемы.
Что я делал:
1) установил в систему node-gyp(через npm), v8, nodejs из репозиториев
2) Добавил в библиотеке метод
void libgt2d::RunCb(v8::Handle<v8::Context> &context, v8::Persistent<v8::Function> &cb)
