Building Cronet (on iOS)

Get source and dependencies

source

• Install depot_tools per https://chromium.googlesource.com/chromium/src/+/master/docs/ios/build_instructions.md

• Make directory for the chromium source, and then fetch: ~ $ mkdir chromium && cd chromium ~/chromium $ fetch --nohooks ios

• Enter the ./src directory: ~/chromium $ cd src

deps

• Download the depenedencies ~/chromium/src $ gclient sync

Build it!

• We'll be using it a bunch, so you may want to put cr_cronet.py in your path. Of course, you can just use its full name every time if you want... ~/chromium/src $ ln -s /path/to/components/cronet/tools/cr_cronet.py /somewhere/in/your/path # or however else you want to do this

This sets up the build directory... ~/chromium/src $ cr_cronet.py gn ...and this builds it! ~/chromium/src $ cr_cronet.py build -d out/Debug-iphonesimulator

• You can also use build-test to run tests on the simulator ~/chromium/src $ cr_cronet.py build-test -d out/Debug-iphonesimulator

• If you want to deploy to hardware, you will have to set up XCode for deploying to hardware, and then use cr_cronet.py gn with the -i flag (for iphoneos build), and cr_cronet.py build with either the -i flag, or using the out/Debug-iphoneos directory. ~/chromium/src $ cr_cronet.py gn -i and then ~/chromium/src $ cr_cronet.py build -i or ~/chromium/src $ cr_cronet.py build -d out/Debug-iphoneos

Updating

• Acquire the most recent version of the source with: ~/chromium/src $ cr_cronet.py sync and then rebuild: ~/chromium/src $ cr_cronet.py build -d out/Debug-iphoneos ~/chromium/src $ cr_cronet.py build -d out/Debug-iphonesimulator

For more information, you can run ~ $ cr_cronet.py -h
