前言

最近好几个项目使用到cef，所以将jcef 的编译过程记录一下

如果要兼容很老的机器如winxp,maven中央库有现成的，直接引用即可

https://mvnrepository.com/artifact/org.bitbucket.johness/java-cef

这个是49版本，有32和64可选，最后一个支持xp系统的，更高的版本最低要求win7.

49版本不支持 es6以上语法，前端打包构建需要转换为es5才可以执行

如果目标平台在win7以上，最好下载最新的jcef进行编译

环境

  1. VMWARE 虚拟机 win7 64

  2. visual studio 2015 c++ 开发环境

  3. CMAKE

  4. GIT 下载地址

    https://github-releases.githubusercontent.com/23216272/9d5ae680-6ae4-11eb-949c-9a5528f8df81?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIWNJYAX4CSVEH53A%2F20210306%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20210306T114253Z&X-Amz-Expires=300&X-Amz-Signature=7857ab73bb80b7090c16c36912563525bba8b981a02df515e042c739ad8e9458&X-Amz-SignedHeaders=host&actor_id=0&key_id=0&repo_id=23216272&response-content-disposition=attachment%3B%20filename%3DGit-2.30.1-64-bit.exe&response-content-type=application%2Foctet-stream

  5. PYTHON 下载地址

    https://www.python.org/ftp/python/2.7.16/python-2.7.16.amd64.msi

    官方推荐2.6+ ，下载2.6.2 结果出错，换成2.7.16没问题

  6. JAVA

本次编译版本为64位，故许准备 64位jdk，版本jdk8以上，设置 JAVA_HOME环境变量，将java bin 目录 添加到path

编译64位库

生成VS 工程

mkdir java-cef && cd java-cef
git clone https://bitbucket.org/chromiumembedded/java-cef.git src
cd src
mkdir jcef_build && cd jcef_build （jcef_build是强制项，必须用此名称）
cmake -G "Visual Studio 14 Win64" ..

生成工程文件的过程中 ，会有两个文件下载比较困难，需要挂代理下载对应的文件

注意点

cef bin 文件下载

https://cef-builds.spotifycdn.com/cef_binary_88.2.6%2Bgd717f0e%2Bchromium-88.0.4324.150_windows64.tar.bz2

文件下载地址会在控制台打印出来，可以复制出来通过代理下载后放入文件夹

C:\Users\Administrator\java-cef\src\third_party\cef

重新跑下生成工程的命令

clang-format.exe 下载

下载地址

https://storage.googleapis.com/chromium-clang-format/b5f5d8d5f8a8fcd2edb5b6cae37c0dc3e129c945

其中md5 是 文件
C:\Users\Administrator\java-cef\src\tools\buildtools\win\clang-format.exe.sha1 的文件内容
该文件在 cmake -G “Visual Studio 14 Win64” .. 生成，但下载的时候回卡住，此时终止脚本运行，去挂代理下载此文件重命名为 clang-format.exe 放入文件夹 C:\Users\Administrator\java-cef\src\tools\buildtools\win\

工程生成成功

make_distrib.bat win64

最终生成目录

C:\Users\Administrator\java-cef\src\binary_distrib

后记

可参考64位编译过程生成32位的库。

cmake -G "Visual Studio 14" ..

一般情况使用32位的库，这样在32和64位平台都通用

如果项目集成了第三方的库，而且第三方只提供了64位的dll，这时就只能使用64位的jcef了

32和64位编译好的库文件共享地址,版本是88 。zip包是7z打的lzma格式的zip包
