我这样做，但没有构建/目录：
gclient config https://webrtc.googlecode.com/svn/trunk
echo "target_os = ['android', 'unix']" >> .gclient
gclient sync --nohooks
然后这里的主干看起来像：
cd trunk
ls -al

我到底做错了什么？我正在克隆r6960。
我找到了gist。基本上我按照以下说明操作：
答案 0 :(得分：0)
当团队进行一些更改时，可能会出现一些迁移问题。
这是我在runhooks期间遇到的：

所以它说有些文件需要移动（在/ trunk / chromium / src 下）。为了安全起见，我将它们移到了主干的外部的其他目录中。
然后我们可以将我们的屁股移回顶部（我的情况是〜/ libjingle）再次重做：

Because chromium/src is transitioning to Git (from SVN), we needed to
change the way that the WebRTC standalone checkout works. Instead of
individually syncing subdirectories of Chromium in SVN, we're now
syncing Chromium (and all of its DEPS, as defined by its own DEPS file),
into the `chromium/src` directory.
As such, all Chromium directories which are currently pulled by DEPS are
now replaced with a symlink into the full Chromium checkout.
To avoid disrupting developers, we've chosen to not delete your
directories forcibly, in case you have some work in progress in one of
them :).
ACTION REQUIRED:
Before running `gclient sync|runhooks` again, you must run:
trunk/setup_links.py --force
Which will replace all directories which now must be symlinks, after
prompting with a summary of the work-to-be-done.
Error: Command /usr/bin/python trunk/setup_links.py returned non-zero exit status 1 in /home/robertwang/libjingle
所以基本上它说他们想将chrome src文件移到其他地方并节省开发人员的时间，请运行setup_links.py来保存任何进一步的问题。
好的，我们这样做：
-> % sudo trunk/setup_links.py

Completed!
Now run `gclient sync|runhooks` again to let the remaining hooks (that probably were interrupted) execute.
最后我们到了这里，走吧！
-> % gclient runhooks
完成时间不应超过1分钟。如需参考，请确保剩余足够的磁盘空间。为了编译这个东西我扩大磁盘空间只是为了得到一个简单的Android apk文件。 ：（
