WebRTC : ninja build not working

问题:

Steps I followed for build of webRTC in UBUNTU env.

Check out the code:

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

Generate ninja makefiles:

cd trunk

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

result of android_gyp:

GYP_GENERATORS set to 'ninja' Updating projects from gyp files... gyp: /home/user/webRTC/trunk/chrome/chrome_resources.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/tools/android/findbugs_plugin/findbugs_plugin.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/sql/sql.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/tools/android/android_tools.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/sync/sync.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/sandbox/sandbox.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/net/net.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/media/media.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/ipc/ipc.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/gpu/gpu.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/components/components_tests.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/base/base.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/breakpad/breakpad.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/base/android/jni_generator/jni_generator.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/third_party/cacheinvalidation/cacheinvalidation.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/remoting/remoting.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/chrome/chrome.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/android_webview/android_webview.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/mojo/mojo.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/content/content_shell_and_tests.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/ui/ui_unittests.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/webkit/renderer/compositor_bindings/compositor_bindings_tests.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/cc/cc_tests.gyp not found (cwd: /home/user/webRTC/trunk) gyp: /home/user/webRTC/trunk/third_party/WebKit/public/all.gyp not found (cwd: /home/user/webRTC/trunk) 

Build and Install Demo app:

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

please let me know if I've donw any steps wrong. I think android_gyp is giving problem, but donno.

Note: I'm using Ubuntu(VMware) on my windows OS

here are my notes for building the AppRTCDemo on Ubuntu 12.04.4, obviously your directories may be slightly different.

## 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 

回答2:

I got the same ninja: error: unknown target 'AppRTCDemo' error on Mac. To resolve this error, I had to specify a valid demo app. For iOS its AppRTCMobile instead of AppRTCDemo as stated in the docs.

ninja -C out/Debug-sim32 AppRTCMobile

The RTC Mobile demo exists in the gclient checkout: src/webrtc/examples/objc

https://chromium.googlesource.com/external/webrtc/+/master/webrtc/examples/objc/AppRTCMobile/
