交叉编译Webkit.doc

交叉编译 Webkit (基于 GTK + DFB )最近为了将webkit移植到arm上奋战了2个多星期，才终于将近20个库全部编译成功。在这个过程中碰到了无数困难，而且网上的很多文章都有问题，即使能将gtk勉强编译成功，也无法使用，故在此将一些信息与需要的人分享。首先有些说明，为了将webkit裁剪的小些，编译中很多功能都disable了，比如多线程。如果需要的人，可以仔细检查每一个configure的选项，将需要的功能enable。其次，此文中需要注意的是pango和gtk的install，本文中提到的olo是intel的arm的机顶盒，感兴趣的同志可以找我：P。因此directFB就有一些我们自己开发的东西，所以编译过程就不放上来了。1.需要的库Name Version Zlib 1.2.3 Libpng 1.2.10 Tiff 3.8.2 Libtool 1.5.24 Jpegb V6b Freetype 2.1.10 Libxml 2.6.30 Fontconfig 2.4.2 Olo directFB In PDK Glib 2.12.0 Atk 1.20.0 Cairo 1.4.2 Pango 1.16.2 Gtk+ 2.10.1 ICU 4c-3-6 Libxslt 1.1.22 Libsqlite 3.5.6 Curl 7.18.0 Webkt r297112.Prepare Working environment 2.1.1 Source cross.shYou can find cross.sh under root directory of subversion.
