ios – 链接器错误 – 使用Cardboard SDK创建MainAppain __EXPECTED_EXACTLY_ONE_VR_MAIN_APP_STATEMENT__

我正在开发一个Google Cardboard应用程序并在iOS中构建良好.但是将Soomla添加到项目会导致链接器错误：

我刚刚将Soomla添加到我的Cardboard应用程序中,但看起来像Soomla和Google Cardboard正在争夺主应用程序(libplatform.a来自Google Cardboard).我认为Google Cardboard需要成为主要的应用程序.

所以,我想知道是否有方法可以使其他插件不为主应用程序而战？

它也可能是其他东西……仅仅是我的理论.

最佳答案 这是因为Xcode构建标志-ObjC,它改变了.a文件的链接方式. Cardboard SDK本身不需要(或想要)的Cardboard .a文件中有一些代码(例如,CreateMainApp).

您可以通过从Xcode中的链接标志中删除-ObjC标志来解决此问题.注意：这可能会导致Soomla无法链接,但希望它们只包含它“以防万一”.所以先尝试一下,如果仍然失败,请在这里评论.
