使用libx264编译Xuggler for Raspberry pi时，问题＃2 [英] Issue #2 when compiling Xuggler for Raspberry pi with libx264
问题描述
我正在为Raspberry Pi（运行在Debian OS上的Raspbian）编译 Xuggler ， / p>
我遵循基本构建说明这里用于编译Xuggler。
在我成功安装所有先决条件并设置正确的路径后，我运行了以下命令：
ant run-tests
我正在面对以下错误，并且在libx264中的ant构建失败：

我无法理解问题说明无法识别的选项'-std = gnu99'在这里，有人可以告诉我如何解决这个问题或在xuggler中规避？
ant run-tests已知在某些架构上失败。当您运行以下命令时，您是否收到相同的错误？
ant stage
我已经使用蚂蚁舞台在Raspberry Pi上成功构建了Xuggler。这产生了可以在许多不同ARM计算机上使用的魔术jar。我个人只想建立一个LGPL版本的图书馆，你可以在这里在pi分支上签出代码：pi / https://github.com/ed/xuggle-xuggler/tree/pi =nofollow> https://github.com/ed/xuggle-xuggler/tree/pi
它不包括X264支持，因为它构建了一个LGPL版本。我知道有可能构建标准的GPL版本，我还没有这样做。你可以看看我做的最后几个提交，看看我改变了什么，让它建立在pi上。
I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),
I followed the 'Basic Build Instructions' available here for compiling Xuggler.
After I successfully installed all the prerequisites and set the correct paths, I ran the following command:
ant run-tests
After sometime I am facing the following error and the ant build fails at libx264:

I am unable to understand the problem statment "unrecognized option '-std=gnu99'" here, Can someone please tell me how can I resolve this or circumvent it in xuggler?
"ant run-tests" has been known to fail on certain architectures. Do you get this same error when you just run the following command?
ant stage
I have successfully built Xuggler on the Raspberry Pi using "ant stage". This produces the magic jar that can then be used on many different ARM computers. I personally was only interested in building an LGPL version of the library, and you can checkout the code that builds as-is on the pi branch here:
https://github.com/e-d/xuggle-xuggler/tree/pi
This does not include X264 support since it builds an LGPL version. I do know that it is possible to build the standard GPL version too, I just haven't done it. You can look at the last few commits I made to see what I changed to get it to build on the pi.
