This directory contains the ObjectiveC implementation of the
webrtc::PeerConnection API. This can be built for Mac or iOS. This
file describes building the API, unit test, and AppRTCDemo sample app.
Prerequisites:
- Make sure gclient is checking out tools necessary to target iOS: your
.gclient file should contain a line like:
target_os = ['ios', 'mac']
Make sure to re-run gclient sync after adding this to download the tools.
- Set up webrtc-related $GYP_DEFINES; example shell functions that set
up for building for iOS-device, iOS-simulator, and Mac (resp) are:
function wrbase() {
cd /path/to/webrtc/trunk
export GYP_DEFINES="build_with_libjingle=1 build_with_chromium=0"
export GYP_GENERATORS="ninja"
}
function wrios() {
wrbase
export GYP_DEFINES="$GYP_DEFINES OS=ios"
export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_ios"
export GYP_CROSSCOMPILE=1
}
function wrios32() {
wrios
export GYP_DEFINES="$GYP_DEFINES target_arch=arm"
}
function wrios64() {
wrios
export GYP_DEFINES="$GYP_DEFINES target_arch=arm64"
}
function wrsim() {
wrbase
export GYP_DEFINES="$GYP_DEFINES OS=ios target_subarch=arm32 target_arch=ia32"
export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_sim"
export GYP_CROSSCOMPILE=1
}
function wrmac() {
wrbase
export GYP_DEFINES="$GYP_DEFINES OS=mac target_subarch=arm64 target_arch=x64"
export GYP_GENERATOR_FLAGS="$GYP_GENERATOR_FLAGS output_dir=out_mac"
}
- Finally, run "webrtc/build/gyp_webrtc" to generate ninja files.
Example of building & using the unittest & app:
- To build & run the unittest (must target mac):
wrmac && ./webrtc/build/gyp_webrtc && \
ninja -C out_mac/Debug libjingle_peerconnection_objc_test && \
./out_mac/Debug/libjingle_peerconnection_objc_test.app/Contents/MacOS/libjingle_peerconnection_objc_test
- To build & launch the sample app on OSX:
wrmac && ./webrtc/build/gyp_webrtc && ninja -C out_mac/Debug AppRTCDemo && \
./out_mac/Debug/AppRTCDemo.app/Contents/MacOS/AppRTCDemo
- To build & launch the sample app on the iOS simulator:
wrsim && ./webrtc/build/gyp_webrtc && ninja -C out_sim/Debug iossim AppRTCDemo && \
./out_sim/Debug/iossim out_sim/Debug/AppRTCDemo.app
- To build & sign the sample app for an iOS device (32 bit):
wrios32 && ./webrtc/build/gyp_webrtc && ninja -C out_ios/Debug-iphoneos AppRTCDemo
- To build & sign the sample app for an iOS device (64 bit):
wrios64 && ./webrtc/build/gyp_webrtc && ninja -C out_ios/Debug-iphoneos AppRTCDemo
