build - WebRTC : ninja build not working

Question

我在 UBUNTU 环境中构建 webRTC 所遵循的步骤。

查看代码:

 gclient config https://webrtc.googlecode.com/svn/trunk
 echo "target_os = ['android', 'unix']" >> .gclient
 gclient sync --nohooks

生成忍者 makefile:

光碟机

 $./build/install-build-deps-android.sh
 $. build/android/envsetup.sh
 Defaulting GYP_GENERATORS to ninja

 $gclient runhooks
 $android_gyp

android_gyp 的结果:

GYP_GENERATORS set to 'ninja'

构建和安装演示应用程序:

$ ninja -C out/Debug video_demo_apk
ninja: Entering directory 'out/Debug'
ninja: error: unknown target 'AppRTCDemo'

如果我有任何错误，请告诉我。我认为 android_gyp 有问题，但不要。

注意:我在 Windows 操作系统上使用 Ubuntu(VMware)

这是我在 Ubuntu 12.04.4 上构建 AppRTCDemo 的笔记，显然您的目录可能略有不同。
