Ffmpeg 使用libx264为Raspberry pi编译Xugler时出现问题2

我正在尝试编译Raspberry Pi（在Debian OS上运行，又称Raspbian）

我遵循了可用于编译Xugler的“基本构建说明”

成功安装所有必备组件并设置正确路径后，我运行了以下命令：

ant run-tests

过了一段时间，我面临以下错误，ant构建在libx264上失败：

我无法理解“Unrecogned option'-std=gnu99'”这一问题，有人能告诉我如何在xuggler中解决或绕过它吗？已知“ant run tests”在某些架构上失败。当您仅运行以下命令时，是否会出现相同的错误

ant stage

我已经成功地用“ant stage”在树莓皮上构建了Xuggler。这就产生了魔法罐，可以在许多不同的ARM计算机上使用。我个人只对构建该库的LGPL版本感兴趣，您可以在这里签出构建pi分支的代码：

这不包括X264支持，因为它构建了LGPL版本。我知道也有可能建立标准的GPL版本，只是我还没有做到。您可以查看我最近的几次提交，看看我做了哪些更改，以使其建立在pi上。

对不起，我以前没有看到过这个错误。我知道Sudhir Kumar（gmail的sudhirm4）已经在pi上构建了支持x264的Xugler。你可以试着和他联系。
