Chromium60编译说明
系统说明
Fedora21系统(Loongson发布的loongnix系统版本为主)—-推荐
Deepin系统
其它系统也可进行源码编译，依赖库有所区别，其它过程都是一样的
代码下载
环境配置
1)安装依赖库
Loongnix系统
yum install gcc-c++ alsa-lib-devel ninja-build atk-devel bison cups-devel dbus-devel expat-devel flex fontconfig-devel GConf2-devel glib2-devel
yum install gtk3-devel glibc-devel gperf libatomic libcap-devel libdrm-devel libgcrypt-devel libudev-devel libusb-devel libXdamage-devel libXScrnSaver-devel
yum install libappstream-glib libgnome-keyring-devel gnome-keyring-devel gtk2-devel
yum install libstdc++-devel openssl-devel libXtst-devel nodejs nss-devel pciutils-devel pulseaudio-libs-devel npm
yum install bzip2-devel dbus-glib-devel elfutils-libelf-devel flac-devel hwdata kernel-headers libevent-devel libffi-devel
yum install libicu-devel libuuid-devel
yum install libudev-devel libxslt-devel opus-devel perl-Switch speech-dispatcher-devel yasm pam-devel
yum install msttcorefonts kochi-substitute-fonts
Deepin系统
apt-get install net-tools git ftp
apt-get install libcups2-dev libnss3-dev libfreetype6-dev libpango1.0-dev libatk1.0-dev libdbus-1-dev libpulse-dev libgtk2.0-dev libffi-dev
apt-get install ninja-build nodejs(nodejs安装后，需执行sudo ln -sv /usr/bin/nodejs /usr/bin/node)
apt-get install libasound2-dev bison gperf libpci-dev libgl1-mesa-dev libxtst-dev libxss-dev libkrb5-dev
2)设置swap分区，防止编译内存地址空间不够
最好设置4G及以上的交换分区
dd if=/dev/zero of=/swapfile bs=1M count=4096
mkswap /swapfile
swapon /swapfile
代码编译
1)先进入$Chromium 目录进行GN_CONFIGS设置。
GN_CONFIG=('google_api_key="AIzaSyDxKL42zsPjbke5O8_rPVpVrLrJ8aeE9rQ"'
'google_default_client_id="595013732528-llk8trb03f0ldpqq6nprjp1s79596646.apps.googleusercontent.com"'
'google_default_client_secret="5ntt6GbbkjnTVXx-MSxbmx5e"'
'clang_use_chrome_plugins=false'
'enable_hangout_services_extension=true'
'enable_nacl=false'
'enable_nacl_nonsfi=false'
'enable_widevine=true'
'fatal_linker_warnings=false'
'ffmpeg_branding="Chrome"'
'fieldtrial_testing_like_official_build=true'
'is_debug=false'
'is_clang=false'
'link_pulseaudio=true'
'linux_use_bundled_binutils=false'
'proprietary_codecs=true'
'remove_webcore_debug_symbols=true'
'symbol_level=0'
'treat_warnings_as_errors=false'
'use_allocator="none"'
'use_cups=true'
'use_gconf=false'
'use_gnome_keyring=false'
'use_gold=false'
'use_gtk3=false'
'use_kerberos=true'
'use_pulseaudio=true'
'use_sysroot=false')
2)GN生成配置
a)下载depot_tools
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=$PATH:$depot_tools(你所下载的depot_tools的绝对路径)
b)python tools/gn/bootstrap/bootstrap.py --gn-gen-args "${GN_CONFIG[*]}"
该过程可能需要设置ninja的路径。
cd ~
git clone https://github.com/martine/ninja.git -b v1.7.2
cd ninja && ./configure.py —bootstrap
export PATH=$ninja:$PATH ($ninja表示ninja所在的绝对路径)
c)out/Release/gn gen out/Release --args="${GN_CONFIG[*]}"
3)代码编译
ninja -C out/Release chrome
执行完，进入out/Release即可发现执行文件chrome，运行需要设置下chrome-sandbox
4)chrome-sandbox设置
ninja -C out/Release chrome_sandbox
进入out/Release，进入如下设置：
mv chrome_sandbox chrome-sandbox
sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox
运行
直接进入out/Release，运行./chrome即可打开你所编译的chromium浏览器了。
安装包制作
目前龙芯chromium只适配了Loongnix系统rpm包：
其它系统，大家可以利用源码自行适配。
