Gentoo Chromium¶
我在完成 在MacBook Pro上安装Gentoo Linux 和 在Gentoo环境安装和使用Sway 之后，首先安装的软件就是浏览器 chromium
现代浏览器编译非常耗时，在我的 MacBook Pro 15” Late 2013 需要花费超过12小时以上才能完成编译
而且 MacBook Pro 15” Late 2013 虽然内存有16GB，但是依然出现 Linux Out Of Memory ，所以我最后采用为主机配置了 8GB Linux swap 才完成编译
USE参数¶
由于我想体验完整的 wayland显示服务器协议 ，所以在 USE 参数中采用了
wayland -x编译安装会提示需要
icu支持，所以按照提示在/etc/portage/package.use/chromium配置以下这些依赖软件包参数:
/etc/portage/package.use/chromium 配置依赖包的USE flag¶dev-libs/libxml2 icu
media-libs/harfbuzz icu
sys-libs/zlib minizip
net-libs/nodejs inspector
修订参数之后需要重建一次整个系统:
在修改了全局 USE flag 之后对整个系统进行更新¶
emerge --ask --changed-use --deep @world
编译安装¶
安装chromium¶
emerge --ask www-client/chromium
原生Wayland支持¶
chromium从 v87 开始原生支持 wayland显示服务器协议 ，但是需要传递以下参数:
chromium原生wayland支持需要传递正确参数¶
chromium --enable-features=UseOzonePlatform --ozone-platform=wayland
也可以通过配置文件传递参数: ~/.config/chromium-flags.conf
通过
~/.config/chromium-flags.conf 传递原生wayland参数给chromium¶--enable-features=UseOzonePlatform
--ozone-platform=wayland
dbus支持¶
虽然chromium没有像firefox那样强制要求 Gentoo D-Bus 支持，但是实际上运行还是会在终端中看到连接 bus 的提示， 虽然似乎不影响运行 :
终端运行
chromium 的一些报错信息，似乎不影响¶...
