构建JDK本身是一个复杂的过程,是无法实现通过一个简单的的javac
呼叫包裹内的蚂蚁
项目。
您应该看看的OpenJDK构建自述以得到关于如何建立你的平台的说明。
I want to compile jdk files in order to include debug infromation.
I'd like to use ant, because it's included in my NetBeans environement, so i've done the following:
<?xml version="1.0" encoding="UTF-8"?> <project name="CompileJDK" default="default" basedir="."> <target name="default"> <javac srcdir="." destdir="jdkwd" debug="on" /> </target> </project>
This leads to 100 compilation errors such as:
[javac] C:\jdkdebug\java\awt\Window.java:196: cannot find symbol
[javac] symbol : class IdentityArrayList
[javac] location: class java.awt.Window
[javac] private static final IdentityArrayList<Window> allWindows = new IdentityArrayList<Window>();
I have just one JDK installed on my machine, so i don't know why it does not resolve all this references.
UPDATE: The majority of these unresolved references belongs to the package:
sun.awt.util
The question now is corrected to: where are the missing jdk files?
Building the JDK itself is a complex process and is not achievable by a simple javac
call wrapped inside an ant
project.
You should look at the OpenJDK Build README to get instructions on how to build for your platform.
