Chromium Embedded Framework

Chromium Embedded Framework
- フレームワークのダウンロード
- フレームワーク入門

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_74.1.16+ge20b240+chromium-74.0.3729.131_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_74.1.16+ge20b240+chromium-74.0.3729.131_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 ..
