Chromium Embedded Framework

Chromium Embedded Framework(CEF) は、Chromiumベースのブラウザを他のアプリケーションに埋め込むための単純なフレームワークである。

chromiumembedded / cef — Bitbucket の Binary Distributions - CEF Automated Builds より cef_binary_3.3626.1886.g162fdec_linux64.tar.bz2(フレームワークのバイナリディストリビューション)をダウンロードする。

クロスプラットフォームのオープンソースビルドシステム CMake をインストールする。バージョン2.8.12.1以降が必要。

$ sudo dnf install cmake

Python をインストールする。バージョン 2.x が必要。

$ sudo dnf install python3

プラットフォーム固有のビルドツールをインストールする。

$ sudo dnf groupinstall "Development Tools"
$ sudo dnf install gcc-c++ gtk2-devel gtkglext-devel

ダウンロードページから、Git コマンドラインツールを使用して、cef-project のソースコードをダウンロードする。

$ git clone https://bitbucket.org/chromiumembedded/cef-project.git

Chromium Embedded Framework (CEF) のバイナリディストリビューションを解凍する。

$ tar jxvf cef_binary_3.3626.1886.g162fdec_linux64.tar.bz2

Makefile を生成する。

$ cd cef_binary_74.1.16+ge20b240+chromium-74.0.3729.131_linux64/
$ mkdir build && cd build
$ cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug ..

CMake Warning (dev) at CMakeLists.txt:187 (find_package):
  Policy CMP0074 is not set: find_package uses <PackageName>_ROOT variables.
  Run "cmake --help-policy CMP0074" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

  CMake variable CEF_ROOT is set to:

    /home/tomoyan/my_projects/cef_binary_74.1.16+ge20b240+chromium-74.0.3729.131_linux64

  For compatibility, CMake is ignoring the variable.
This warning is for project developers.  Use -Wno-dev to suppress it.
