Compile OpenJDK7 source code on CentOS6.5

This article address: http://www.cnblogs.com/wuyudong/p/build-openjdk7.html, reprint please indicate source address.

Using the open source version of OPENJDK, there are two ways to get its source code:

• The Mercurial Code versioning tool takes the source directly from the repository, but is too slow to take several hours

• Download the official packaged source package directly (recommended)

Download source Openjdk-7u6-fcs-src-b24-28_aug_2012.zip, unzip, as follows:

Http://www.java.net/download/openjdk/jdk7u6/promoted/b24/openjdk-7u6-fcs-src-b24-28_aug_2012.zip

This compilation uses a 64-bit OS and compiles 64-bit JDK, which requires at least 512MB of memory

1. Basic process

(Read the Readme and readme-builds.html)

The readme-builds.html contains detailed installation information, preferably a complete reading.

2. Install the base package

My centos6.5 is installed on VMWARE10 and installed with minimal (Minimal) installation

[Email protected] ~]# Cat/etc/redhat-releasecentos release 6.5 (Final) [[email protected] ~]# Uname-mx86_64[[email prote CTED] ~]# uname-r2.6.32-431.el6.x86_64

Configuring the update source

The current wget is not yet available.

To install the JDK:

Unzip the Jdk-6u26-linux-i586.bin to the application/java/directory

Set the environment variables as follows:

#set java environmentjava_home=/application/java/jdkexport jre_home=/application/java/jdk/jreexport CLASSPATH=.:$ Java_home/lib: $JRE _home/lib: $CLASSPATHexport path= $JAVA _home/bin: $JRE _home/bin: $PATH

Install Ant:

Cd/application/tools/unzip Apache-ant-1.7.1-bin.zip ln-s/application/tools/apache-ant-1.7.1/bin/ant/usr/bin/ant

Check for Java and ant:

[[email protected] ~]# Java-versionjava version "1.6.0_26" Java (TM) SE Runtime Environment (build 1.6.0_26-b03) Java HOTSPO T (TM) 64-bit Server VM (build 20.1-b02, Mixed mode) [[email protected] ~]# AntBuildfile:build.xml does not exist! Build failed

3. Configuring variables

Nset classpathunset java_homeexport lang=cexport alt_bootdir=/application/java/jdkexport ANT_HOME=/application/ Tools/apache-ant-1.8.1/export Alt_freetype_lib_path=/usr/local/libexport Skip_debug_build=falseexport SKIP_ Fastdebug_build=trueexport Debug_name=debugexport Alt_freetype_headers_path=/usr/local/include/freetype2

4. Check whether the environment is configured OK and compile the JDK source code

[[Email protected] tools]# CD Openjdk[[email protected] openjdk]# Pwd/application/tools/openjdk[[email protected] openjdk]# Make Sanity

openjdk-specific Settings:
Freetype_headers_path =/usr/local/include/freetype2
Alt_freetype_headers_path =/usr/local/include/freetype2
Freetype_lib_path =/usr/local/lib
Alt_freetype_lib_path =/usr/local/lib

Previous JDK Settings:

Previous_jre_file =
Alt_previous_jre_file =
previous_release_image =/application/java/jdk
alt_previous_release_image =

Sanity check passed.
