- Install mercurial and trees plugin. OpenJDK repository and its developer guide is http://openjdk.java.net/guide/repositories.html.
- Clone OpenJDK 8 repositories
hg tclone http://hg.openjdk.java.net/jdk8/jdk8
- Install bootstrap JDK
sudo apt-get install openjdk-7-jdk
It also installs several extra packages such as libx11-dev, libxt-dev which are necessary when building OpenJDK later. - Install essential packages
sudo apt-get install build-essential zip libcups2-dev libfreetype6-dev libasound2-dev
These dependency packages are well prompted by configure script. Detailed document is at hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html. - Set bootstrap JDK path
export PATH=/usr/lib/jvm/java-7-openjdk-amd64/bin:$PATH
- Configure
bash ./configure
You will probably see output as followsA new configuration has been successfully created in /home/frank/Desktop/openjdk/jdk8/build/linux-x86_64-normal-server-release using default settings. Configuration summary: * Debug level: release * JDK variant: normal * JVM variants: server * OpenJDK target: OS: linux, CPU architecture: x86, address length: 64 Tools summary: * Boot JDK: java version "1.7.0_55" OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1~deb7u1) OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode) (at /usr/lib/jvm/java-7-openjdk-amd64) * C Compiler: gcc-4.7 (Debian 4.7.2-5) version 4.7.2 (at /usr/bin/gcc-4.7) * C++ Compiler: g++-4.7 (Debian 4.7.2-5) version 4.7.2 (at /usr/bin/g++-4.7) Build performance summary: * Cores to use: 1 * Memory limit: 1002 MB * ccache status: not installed (consider installing) Build performance tip: ccache gives a tremendous speedup for C++ recompilations.
