Mac 下 chromium 源码编译

Jackey 其他 335 次浏览 , 没有评论

需要安装xcode、git

环境配置

配置命令行科学上网方式:

// 设置终端git代理 为CURL设置proxy
git config –global http.proxy ‘socks5://127.0.0.1:1086’
git config –global https.proxy ‘socks5://127.0.0.1:1086’

// 为wget设置proxy
export http_proxy=127.0.0.1:1087
export https_proxy=127.0.0.1:1087

// 最终记得取消git代理
git config –global –unset http.proxy
git config –global –unset https.proxy

//获取depot_tools代码管理工具
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
//配置path,替换实际地址(可以添加到环境变量)
export PATH=$PATH:/Users/jackey/liulanqi/chromium/depot_tools

拉取源码

fetch chromium

或者网络不好时不下载历史:

fetch chromium –no-history

注意:强烈建议找个稳定的科学上网工具,或者直接买个国外的服务器下载好源码再弄到本地来,git拉取源码不稳定是不行的,不支持断点续传,源码二十多个G。本人刚开始尝试本地拉取,更换了好几个工具,最后还是购买了一台香港服务器搞定的。在服务器上运行(香港服务器拉取源码的速度高达11M/s,满脸都是泪呀):

git clone https://chromium.googlesource.com/chromium/src.git

然后打包下载到本地。

解压到本地后,进入chromium目录,编辑.gclient 文件:

vim .gclient

在尾部添加:

target_os = [‘mac’]

切记:这样子拉下来的是master分支,强烈建议切换到release分支再编译,否则编译的时候会报各种错误,切换方法:

以下命令需要在科学上网环境下运行。

// 同步所有 tag 信息
git fetch –tags
// 从 tag 创建新的构建 branch(查看所有 tag: git show-ref –tags)
git checkout -b browser 85.0.4183.104
// 切换分支后同步代码
gclient sync

此命令需要下载15G左右的文件。

大概执行一个小时左右。

编译

执行完成之后,运行命令:

gn args out/default

注意:这里可能会报错无权限,需要执行:

chomd a+x gn

会打开一个文件,在尾部添加:

target_os = “mac”
target_cpu = “x64”
is_debug = false
is_component_build = false

保存退出,等其执行完毕,不报错即可。

然后执行编译命令:

ninja -C out/default chrome

需要编译四千多个文件,编译时间视编译机器的配置,快的话七八个小时,慢的话可能会一天一夜哦!

其他

使用Xcode来构建Chromium,我们要使用Xcode来阅读和调试Chromium代码,因此我们需要执行

gn gen out/gn –ide=xcode

在用Ninja和GN构建完成之后,执行这条命令需要的时间就比较少了。然后就可以用Xcode来打开这个工程了。执行

open out/gn/ninja/all.xcworkspace

排错记录

报错:

OSError: [Errno 13] Permission denied
Error: Command ‘vpython src/build/mac_toolchain.py –xcode-version default’ returned non-zero exit status 1 in /Users/fengyu/chromuim/chromium

解决方法:
debug 方法:
vim src/build/mac_toolchain.py
找到第70行
def _UseHermeticToolchain():
current_dir = os.path.dirname(os.path.realpath(__file__))
script_path = os.path.join(current_dir, ‘mac/should_use_hermetic_xcode.py’)
proc = subprocess.Popen([script_path, ‘mac’], stdout=subprocess.PIPE)
return ‘1’ in proc.stdout.readline()

将其修改为:
def _UseHermeticToolchain():
current_dir = os.path.dirname(os.path.realpath(__file__))
script_path = os.path.join(current_dir, ‘mac/should_use_hermetic_xcode.py’)
print(script_path)
sys.exit(0)
proc = subprocess.Popen([script_path, ‘mac’], stdout=subprocess.PIPE)
return ‘1’ in proc.stdout.readline()
然后运行:vpython src/build/mac_toolchain.py –xcode-version default
查看输出文件的路径,给其赋权如下:
chmod a+x /Users/fengyu/chromuim/chromium/src/build/mac/should_use_hermetic_xcode.py

Ubuntu 编译

参考:https://chromium.googlesource.com/chromium/src/+/master/docs/android_build_instructions.md

编译的过程会报权限错误,需要将整个chromium文件件赋予776权限。

chromd -R 776 chromium

win10 编译

配置以下系统环境变量

变量:HTTP_proxy     值:http://127.0.0.1:1080

变量:HTTPS_proxy     值:http://127.0.0.1:1080
