How to build and package OpenJDK 7 on Linux

Some pre-requisites are required to build OpenJDK7 on Linux

Build and package pre-requisites

Be sure to have git, mercurial, gcc/g++, make and required libs and some mandatory tools installed. Java 6 or 7 should be installed. Ensure JAVA_HOME env var point to a valid JDK location

openSUSE / SLES

sudo zypper install git-core mercurial zip bzip2 unzip tar 
sudo zypper install ccache make gcc gcc-c++ ca-certificates-cacert ca-certificates-mozilla
sudo zypper install libstdc++-devel alsa-devel cups-devel xorg-x11-devel libjpeg62-devel giflib-devel 
sudo zypper install curl rpm gpg
sudo zypper install java-1_6_0-openjdk-devel (or java-1_7_0-openjdk-devel)

CentOS 5/6

sudo yum install git-core mercurial zip bzip2 unzip tar 
sudo yum install ccache make gcc gcc-c++ libstdc++-devel 
sudo yum install alsa-lib-devel cups-devel libX11-devel libXext-devel libXt-devel libXrender-devel libXtst-devel libXi-devel libjpeg-devel giflib-devel freetype-devel
sudo yum install curl rpm-build gpg
sudo yum install java-1.6.0-openjdk-devel (or java-1.7.0-openjdk-devel)

Fedora 16/17

sudo yum install git-core mercurial zip bzip2 unzip tar 
sudo yum install ccache make gcc gcc-c++ 
sudo yum install libstdc++-devel libstdc++-static alsa-lib-devel cups-devel libX11-devel libXext-devel libXt-devel libXrender-devel libXtst-devel libXi-devel libjpeg-devel giflib-devel freetype-devel 
sudo yum install curl rpm-build gpg rpmbuild rpm-sign
sudo yum install java-1.6.0-openjdk-devel (or java-1.7.0-openjdk-devel)

Prepare environment

For example, you want to build OpenJDKs in openjdkathome directory under your home directory.

mkdir ~/openjdkathome
cd ~/openjdkathome
git clone https://github.com/hgomez/obuildfactory.git

Building OpenJDK

Building is activated by XBUILD env var set to true

cd ~/openjdkathome
XBUILD=true ./obuildfactory/openjdk7/linux/standalone-job.sh

After some minutes you should see this logs :
