WebKit內核編譯

WebKit內核編譯實在是一項折磨人的事情，雖然webkit.org官方有一個文檔，但是有時候機器本身配置環境還是和教程有差別。

經過三天三夜平均每天2點鍾的奮斗，今天終於搞定了。

其實，官方的描述已經非常到位，只要保證每一步都執行了，差別應該不大，需要多加處理的就是本機實際環境導致的具體問題。

首先按照官方文檔進行操作

http://www.webkit.org/building/tools.html

一、安裝Visual 2005

1. If you own Visual Studio 2005 (newer versions of Visual Studio are currently unsupported):

   Install Microsoft Visual Studio 2005 Team Suite Service Pack 1.

   If you are building from Vista, install Service Pack 1 Update for Windows Vista.

   Install Visual Studio 2005 Service Pack 1 ATL Security Update.

   Install the following hotfixes to improve Visual Studio's performance and responsiveness:

   1. KB918559
   2. KB935225
   3. KB943969
   4. KB947315

   Use the default options for these installations.

（我在裝下面四個補丁的時候提示找不到升級的程序，我裝的是2005 中文版，估計補丁有問題，后來沒有理會了）

二、安裝cygwin

1. Install Cygwin

   Cygwin is a collection of utilities for Windows that includes not only a Subversionclient, but also additional tools that are required to build the WebKit source. Wehave made a downloader available that automatically collects all of the requiredpackages.

   Download cygwin-downloader.zip.

   Extract the content of the archive to some folder and start cygwin-downloader.exe from that folder.This will download all the Cygwin packages you need.

   When all the packages have finished downloading, the Cygwin installer will launch. ChooseInstall from Local Directory, then clickNext until theinstall is complete. If you are running Vista, the installer won't be able to launch automatically, so you will have to manually launch Cygwin's Setup.exe.

   Note: If you are behind a proxy you need to set the http_proxy environment variable to the URL of the proxy. This wouldlikely match this pattern:http[s]://[username[:password]@]somehost.com[:port]. Where the square brackets ([]) are not part of the url but enclose url elements that are optional indicating that those elements might be missing in your case together with their enclosed delimiter such as @ and :.

   Note: Vista may warn you that Cygwin did not install correctly. Ignore this warning and tell Vista that the install was successful.

   Warning: If you are running Vista or Windows 7, Cygwin may have trouble with implementingfork(the POSIX function frequently used to start child processes, needed by many of the WebKit build tools).In order to enablecygwin1.dll to implement fork successfully it is better if no DLL loaded in the parent process is relocated at runtime.One way to achive this is to rebase all cygwin dlls exceptcyglsa64.dllandcygwin1.dll to base addresses that cause them to not overlap in memory.

   In order to rebase all cygwin dlls a rebaseall script is provided in the cygwin installation'sbindirectory(usuallyC:\cygwin\bin).This script must be run fromash.exe (found in the same directory) while no other cygwin application is running.
   ash.exe has very limited command line editing features so cutting and pasting to the commandline is recommended.
   The PATH environment variable may not contain the /bin directory by defaultthus the script should be launched as/bin/rebaseall.
   If rebaseall is complaining about failure to write to a Windows Temp directory (i.e./cygdrive/c/Users/you/AppData/Local/Temp),fix the permissions on that folder (i.e./bin/chown you /cygdrive/c/Users/you/AppData/Local/Temp) orchange the TMP environment variable to point to a directory with the appropriate permission flags (i.e.:export TMP=/tmp).

   Note: The rebase process may need to be repeated to include any new libraries added later to cygwin by listing these libraries by full cygwin path in a file and passing the file torebaseall via the-T fileNamecommandline argument.The dlls underLayoutTests/http/conf are a relevant use case.

   Remove the following lines from /home/[username]/.bashrc (if present):

   unset TMP
   unset TEMP
   Those lines would prevent picking up the Windows TMP and TEMP environment variables.

   If you are behind a proxy you need to do the following to allow cygwin svn to get through the proxy (similar steps are available for your Windows svn):

   • In bash (Cygwin) run: svn help. This will create in your cygwin home directory the file .subversion/servers.
   • Edit the file mentioned above and follow the instructions in the file to set up your proxy settings.

（上面的每一步都要執行，包括用他cygwin配置，執行ash.exe /binrebaseall）

三 安裝 QuickTime SDK和 DirectX SDK

1. Install QuickTime SDK

   Download QuickTime SDK for Windows from http://developer.apple.com/quicktime/download/ and install it to the default location (\Program Files\QuickTime SDK). This is needed for media support.

2. Install DirectX SDK

   Download the February 2010 DirectX SDK (newer versions do not support Visual Studio 2005). This is needed for accelerated compositing.

（都要裝）

四 其他 

1. Optional: Install the 32-bit version of Debugging Tools for Windows

   Debugging Tools for Windows includes many useful debugging tools such as WinDbg and NTSD. Some of WebKit’s tests and scripts use these tools. Follow theinstructions for installing the 32-bit version of Debugging Tools for Windows.

2. Optional: Hotfix for 64-bit Windows to disable the user-mode callback filter for exceptions

   Without the 976038 hotfix, exceptions may be thrown in callback routines that do not cause a crash but leave the application in an inconsistent state that might cause a crash later. You will need to click on "View and request hotfix downloads" and fill out the form. A link to download the hotfix and a password will be emailed to you.

（編譯通過的時候這些我沒裝），最后還是通過了。

五 總結一下

需要我們自己做的事情

更改VC為DEBUG、設置“警告作為錯誤”為false、

編譯錯誤和解決

首先，這一篇文檔算是比較全的。

http://hi.baidu.com/ksoftware/blog/item/75dace1f94750179f724e457.html

                      重新生成，成功。
      6) ERROR # error C2220: 警告被視為錯誤 - 沒有生成“object”文件

（我下載的是WebKit-r94831.tar.bz2 ，遇到了ERROR # error C2220: 警告被視為錯誤 - 沒有生成“object”文件，要安裝上面修改，於此同時要關閉警告被視為錯誤的VC編譯選項）

這篇博客說，是google STL有關，要修改 WebKit/WebCore/config.h里面，在<wtf/platform.h>上面加上

#define _HAS_EXCEPTIONS 0
#define _STATIC_CPPLIB

但是，我這么做事失敗了的。搞了很久發現自己有一個東西忘安裝了Install Microsoft Visual C++ Express 2005 Service Pack 1，官方下載的是

VS80sp1-KB926601-X86-ENU.exe，其實這個我這里裝不起，后來裝了VS80sp1-KB926604-X86-CHS.exe，才解決了這個問題。

google搜索是什么icu3.2 icu4.0的東西，后面涉及到什么VS2005 2008沖突。

這個問題，我遇到沒搞定，后來重裝的系統，這個問題就沒出現了。

這個就是不斷查找，不斷嘗試，本來都打算放棄了的，但是不甘心，最后終於成功了，也祝大家編譯順利。
