WebRTC：忍者构建不起作用答案

【问题标题】：WebRTC : ninja build not workingWebRTC：忍者构建不起作用
【发布时间】：2013-11-18 12:14:41
【问题描述】：

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：

cd 后备箱

 $./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：

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

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

注意：我在我的 Windows 操作系统上使用 Ubuntu(VMware)

这个问题你解决了吗？我也有同样的问题
可能有点晚了，但希望该教程对您有很大帮助。访问参考：WebRtc_Library_Compilation

【解决方案1】：

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。

## building webrtc

# install dependencies:
sudo apt-get install git git-svn subversion g++ python libnss3-dev libasound2-dev libpulse-dev libjpeg62-dev libxv-dev libgtk2.0-dev libexpat1-dev lib32asound2-dev ia32-libs

# create a working directory:
mkdir -p ~/git/working

cd ~/git/working

# get the depottools:
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

# Add depot_tools to your PATH:
echo "PATH=\$PATH:$HOME/git/working/depot_tools" >> ~/.bash_aliases
echo "export PATH" >> ~/.bash_aliases
. ~/.bash_aliases

# get the WebRTC source:
gclient config http://webrtc.googlecode.com/svn/trunk

# configure for android:
echo "target_os = ['android', 'unix']" >> .gclient

# synchronize:
gclient sync --nohooks

# set up env variables:
source ~/git/working/trunk/build/android/envsetup.sh

# install new dependencies:
sudo ~/git/working/trunk/build/./install-build-deps-android.sh
sudo ~/git/working/trunk/build/./install-build-deps.sh

# Set up webrtc-related GYP variables:
export GYP_DEFINES="build_with_libjingle=1 build_with_chromium=0 libjingle_java=1 $GYP_DEFINES"

# generate the build scripts:
gclient runhooks

# install find_depot_tools dummy file:
wget -O ~/git/working/trunk/build/find_depot_tools.py http://webrtc.googlecode.com/svn/trunk/webrtc/build/find_depot_tools.py

# build the Debug version of the AppRTCDemo:
ninja -C out/Debug AppRTCDemo

【讨论】：

您发布了一些 32 位的软件包，这些软件包是干什么用的？如果用户是 Ubuntu 64 位用户，他应该安装相同的软件包吗？如果没有，请在此处发表评论。
2014-05-05 19:08:44 ERROR 404: Not Found. - ninja -C 之前的最后一行失败了 url 文件 find_depot_tools.py 丢失，因此它无法正常工作，您可以更新一下吗？
使用这里的文件：github.com/adobe/chromium/blob/master/tools/find_depot_tools.py，然后再次尝试ninja -C trunk/out/Debug AppRTCDemo，但仍然失败，说：ninja error: unknown target 'AppRTCDemo'
进入主干文件夹；在 ninja build 命令之前运行“webrtc/build/gyp_webrtc”。如果 AppRTCDemo 仍然未知，只需运行“ninja -C out/Debug”。
原find_depot_tools.py可以在这里找到：code.google.com/p/webrtc/source/browse/trunk/webrtc/build/…这个解决方案很好用，谢谢

【解决方案2】：

我在 Mac 上遇到了同样的 ninja: error: unknown target 'AppRTCDemo' 错误。为了解决这个错误，我必须指定一个有效的演示应用程序。对于 iOS，它是 AppRTCMobile 而不是文档中所述的 AppRTCDemo。

ninja -C out/Debug-sim32 AppRTCMobile

gclient 结帐中存在 RTC Mobile 演示：src/webrtc/examples/objc
