这是我在 pi 论坛上的第一篇文章。我的 pi 昨天到了，我真的很高兴让我的应用程序在 pi 上运行。

我想做以下事情......我想用播放列表中的当前歌曲制作一个简单的播放列表。应该只显示前 4 首歌曲的封面。我已经使用 XNA 在 VB.Net 中完成了这项工作。我试图将它移植到monogame，GraphicsModeException在PI上运行时使用OpenTK。

即使是一个小的"Hello World"字符串渲染也会失败，并出现同样的异常。一切都是通过简单的 spritebatch 渲染完成的

有什么建议么 ？

Mono 仅支持 softfloat 模式，而大多数 RPi 操作系统默认为 hardfloat。我相信下一个单声道版本计划支持 hardfloat。如果你从 git repo 构建单声道源，你现在可以得到它。
