Gentoo下编译webkit
方法很简单：
1.
mkdir ~/webkit
cp /usr/portage/distfiles/webkit-1.1.10.tar.gz ~/webkit
2.解压
cd ~/webkit
tar xvf webkit-1.1.10.tar.gz
3.配置，都用得默认配置
cd webkit-1.1.10
./configure
...
WebKit was configured with the following options:
Build configuration:
Enable debugging (slow) : no
Enable GCC build optimization : yes
Code coverage support : no
Unicode backend : icu
Font backend : freetype
Optimized memory allocator : yes
Features:
3D Transforms : no
JIT compilation : yes
Dashboard support : yes
Filters support : no
Geolocation support : no
GNOME Keyring support : no
JavaScript debugger/profiler support : yes
HTML5 offline web applications support : yes
HTML5 channel messaging support : no
HTML5 client-side session and persistent storage support : yes
HTML5 client-side database storage support : yes
HTML5 video element support : yes
Icon database support : yes
SVG support : yes
SVG animation support : yes
SVG fonts support : yes
SVG foreign object support : yes
SVG as image support : yes
SVG use element support : yes
WML support : no
Web Workers support : yes
XPATH support : yes
XSLT support : yes
GTK+ configuration:
GDK target : x11
Hildon UI extensions : no
可以看到默认的配置都设置了什么。
4.编译
make
5.编译好后，会生成Programs目录，编译过程用了大概30分钟的样子。
pjq@gentoo-pjq ~/webkit/webkit-1.1.10 $ ls Programs/ -lR

其中GtkLauncher是一个简单的GTK浏览器。
6.打开这个简易的浏览器
./Programs/GtkLauncher
这个简易浏览器的源码在：WebKitTools/GtkLauncher/main.c
pjq@gentoo-pjq ~/webkit/webkit-1.1.10 $ cat WebKitTools/GtkLauncher/main.c

}
主要就调用了三个函数：
gtk_box_pack_start (GTK_BOX (vbox), create_toolbar (), FALSE, FALSE, 0);
gtk_box_pack_start (GTK_BOX (vbox), create_browser (), TRUE, TRUE, 0);
gtk_box_pack_start (GTK_BOX (vbox), create_statusbar (), FALSE, FALSE, 0);
分别创建了toolbar,browser,statusbar.
以后应该就可以用这个来调试WebKit了。
这个WebKit应该只是针对GTK的精简版了，完整版比这个复杂多了。
以后再研究一下完整版的编译过程。
