调用AssetsManager相关代码后cclog打印的都是乱码

Cocos2d-x
#1 
bool CUpdateManager::initInfo(std::string url_pack, std::string url_version, std::string save_dir)
{
    Layer::init();
    m_pLuaEngine = LuaEngine::getInstance();

    pAssetsManager = new cocos2d::extension::AssetsManager(url_pack.c_str(), url_version.c_str(), save_dir.c_str());

    pAssetsManager->setDelegate(this);
    pAssetsManager->setConnectionTimeout(3);
    addChild(pAssetsManager);
    pAssetsManager->release();
    
    createDownloadedDir();
    return true;
}

调用这个函数之后打印就乱码了
