DEPRECATED

Instructions on this page are out of date. If you come into issues then ask for help on the Forum. The process of building CEF is now automated with the pycef/tools/automate.py tool. See pycef/docs/Build-instructions.md for CEF build instructions for Chrome 47 or later releases.

Build instructions for Mac

The original instructions on building Chromium/CEF can be found on the CEF project Branches and Building wiki page.

Table of contents:

Preliminary notes

  • These instructions were tested using:
    • OS X 10.9.4 Mavericks
    • Fresh install of Python 2.7.9 from python.org
    • XCode 4.6.3
    • Command Line Tools for XCode, Apr 2014
  • XCode 6 is not supported by CEF (officially)

TODO

  • Fix HTTPS caching on sites with SSL certificate errors (optional)
  • Disable the tcmalloc memory allocation global hook (optional, but recommended) - Issue 155

Prepare environment

You need to set the following environment variables:

  • CC=gcc
  • CXX=g++
  • CEF_CCFLAGS and ARCHFLAGS - either "-arch i386" when building 32bit or "-arch x86_64" for 64bit

If you're building 32bit on 64bit then:

  • Create an alias python="arch -i386 python"
  • Set the CEF_CCFLAGS and ARCHFLAGS env variables to "-arch i386"

An example script to prepare 32-bit environment

Save it as mac32.sh and type "source mac32.sh".

#!/bin/bash

PATH=/usr/local/bin:$PATH
export PATH
alias python="arch -i386 python"

CEF_CCFLAGS="-arch i386"
export CEF_CCFLAGS

ARCHFLAGS="-arch i386"
export ARCHFLAGS

export CC=gcc
export CXX=g++

An example script to prepare 64-bit environment

Save it as mac64.sh and type "source mac64.sh".

#!/bin/bash

PATH=/usr/local/bin:$PATH
export PATH

CEF_CCFLAGS="-arch x86_64"
export CEF_CCFLAGS

ARCHFLAGS="-arch x86_64"
export ARCHFLAGS

export CC=gcc
export CXX=g++

Install Cython

Download Cython 0.19.2 from PYPI. Latest versions are not supported, see Issue 110.

https://pypi.python.org/pypi/Cython/0.19.2

Extract it and install. Before installing make sure you have exported the CC, CXX and ARCHFLAGS environment variables. Cython compilation will fail if it tries to compile for both 32bit and 64bit, that's why it is required to set ARCHFLAGS to either 32bit or 64bit architecture.

python setup.py install

Download CEF binaries and build cefclient

Download CEF ready binaries from cefbuilds.com. The branch and revision must match with the ones provided in the BUILD_COMPATIBILITY.txt file.

Extract the archive. In our case this will create the cef_binary_3.1650.1639_macosx32 directory to which we will later reference as the cef_binary directory.

Open the cefclient.xcodeproj project. When using Xcode 4.2 or newer you will need to change the "Compiler for C/C++/Objective-C" setting to "LLVM GCC 4.2" under "Build Settings" for each target.

Change build configuration to Release. From menu: Product > Scheme > Edit Scheme > Run > Build configuration: Release and OK. Click the Run button to build the project.

If there are errors while compiling cefclient_osr_widget_mac.mm then fix them:

  • Remove the "(readwrite, atomic)" string that appears before "bool was_last_mouse_down_on_view"
  • Move the sendScrollWheelEvet method up in the source file before it is referenced by the shortCircuitScrollWheelEvent method

Go to the xcodebuild/Release/ directory and run cefclient.app to see if everything works fine.

Download the CEF Python sources

git clone https://github.com/cztomczak/cefpython

Copy CEF binaries and libraries to the CEF Python directories

  • Copy "cef_binary/xcodebuild/Release/libcef_dll_wrapper.a" to "src/mac/setup/lib_32bit/"
  • Copy "cef_binary/Release/*.dylib|so" to "src/mac/binaries_32bit/"
  • Copy "cef_binary/Resources/" to "src/mac/binaries_32bit/Resources/"

Build the CEF Python module

cd src/mac/
python compile.py

Build packages for distribution

cd src/mac/installer/
./build_all.sh

This should create dist/ directory with a Python Wheel package and a Distutils source package.

If you've built the cefpython module for both 32bit and 64bit and binaries are available in both mac/binaries_32bit/ and mac/binaries_64bit/ directories, then the setup script will create packages with fat binaries that can run on both 32bit and 64bit.
