WebRTC : ninja build not working

Question

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 = [         


        

Answer 1

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/

Answer 2

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
