有人可以帮助我吗，谢谢各位。我已经检查过 SDL.Framework我没有看到任何问题。我是否必须在我的项目中添加一些库才能运行这个项目或在 mac 中。

Answer 1

ffmpegdecoder.framework 中的 ffmpeg 版本不是为模拟器构建的。这表明您正在为模拟器构建。

架构 i386 的 undefined symbol :

将项目设置更改为 release ，从您的拱门中删除 armv7s，它应该构建得很好。

在模拟器上运行并不能很好地代表像这样使用 iPhone GPU 的项目。

如果您在构建时遇到问题，或者您绝对必须在模拟器上运行，请联系 michelle@mooncatventures.com，我们绝对可以帮助您进行这些更改。
