Building Chromium Embedded Framework for ValaCEF

You need patched CEF 76.3809.x.

Paths

  • /media/fenryxo/exthdd7/cef/build/ -- the build directory
  • /media/fenryxo/exthdd7/cef/build/ -- the download directory
  • /home/fenryxo/dev/projects/cef/cef -- the source directory of patched CEF 76.3809.x

Install dependencies

On Ubuntu 18.04 LTS:

apt install \
  curl build-essential flex g++ git-svn libcairo2-dev libglib2.0-dev \
  libcups2-dev libgtkglext1-dev git-core libglu1-mesa-dev libnspr4-dev \
  libnss3-dev libgnome-keyring-dev libasound2-dev gperf bison libpci-dev \
  libkrb5-dev libgtk-3-dev libxss-dev python libpulse-dev ca-certificates \
  default-jre

Use LXC container (here in Fedora 29):

sudo lxc-create -n cef-bionic -t /usr/share/lxc/templates/lxc-download  -- -d ubuntu -r bionic -a amd64
sudo lxc-start -n cef-bionic
sudo lxc-attach -n cef-bionic
    apt update && apt full-upgrade
    apt install ...
    mkdir -p /media/fenryxo/exthdd7/cef
    poweroff
sudo nano /var/lib/lxc/cef-bionic/config
    lxc.mount.entry = /media/fenryxo/exthdd7/cef media/fenryxo/exthdd7/cef none bind 0 0

Download automate-git.py script

mkdir -p /media/fenryxo/exthdd7/cef/build
cd /media/fenryxo/exthdd7/cef/build
wget https://bitbucket.org/chromiumembedded/cef/raw/master/tools/automate/automate-git.py

Set up environment

sudo lxc-start -n cef-bionic
sudo lxc-attach -n cef-bionic
apt update; apt full-upgrade
su ubuntu
cd /media/fenryxo/exthdd7/cef/build
export GN_DEFINES='is_official_build=true use_allocator=none symbol_level=1 ffmpeg_branding=Chrome proprietary_codecs=true'
export CFLAGS="-Wno-error"
export CXXFLAGS="-Wno-error"
export CEF_ARCHIVE_FORMAT=tar.bz2

Install CEF to be found by ValaCEF

In the directory of an extracted minimal CEF distribution:

mkdir -p build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..
make
su # or sudo su
mkdir -p /usr/local/include/cef
cp -r include /usr/local/include/cef
mkdir -p /usr/local/lib/cef
cp -r Release/* /usr/local/lib/cef
cp build/libcef_dll_wrapper/libcef_dll_wrapper.a /usr/local/lib/cef/libcef_dll_wrapper.a
cp -r Resources/* /usr/local/lib/cef

If you use a non-standard prefix (i.e. different than /usr, /usr/local, /app), use CEF_PREFIX=/myprefix to build ValaCEF.

Issues

curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

This happens behind a HTTP proxy.

  • Use a VPN connection tunnelled through the proxy
  • unset http_proxy; unset https_proxy
  • nano /etc/resolv.conf

Build cefclient

  • apt install libgtk2.0-dev libgtkglext1-dev cmake
  • mkdir build && cd build
  • cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug ..
  • make -j4 cefclient cefsimple
