On Fedora 9 the OpenJDK 6 runtime and development packages are installed by default during any large-media install, such as from the Fedora 9 DVD.
If installing from a live image, such as a live CD or USB flash drive, add the OpenJDK 6 runtime after the install:

• To install with the graphical package manager, follow Applications > Add/Remove Software and use search to find the package(s) to install.
• To install from the command line:

  $ su -c "yum install java-1.6.0-openjdk"

  This package contains just the Java Runtime Environment. If you want to develop Java programs then install the java-1.6.0-openjdk-devel package. You can also install all the OpenJDK 6 packages, including the API documentation, by using the wildcard java-1.6.0-openjdk*.
  

On Fedora 8 the OpenJDK 7 runtime and development packages are installed by default during any large-media install, such as from the Fedora 8 DVD, under the name IcedTea. If installing from a live image then follow the above instructions but replace 1.6.0-openjdk with 1.7.0-icedtea.

Red Hat Enterprise Linux, CentOS, etc.

The OpenJDK 6 packages are also available in EPEL, a community-run project which makes Fedora packages available to users of Red Hat Enterprise Linux 5, CentOS 5, and other RHEL 5 derivatives.

$ su -c "rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-2.noarch.rpm"

Then add the OpenJDK 6 runtime, or the development package and related packages if so desired, by following the instructions above for Fedora.

We are working on putting everything in place to start providing OpenJDK 7 builds in OpenSolaris package repositories beginning in July 2009.
If you want to have a head start, you can build OpenJDK 7 on OpenSolaris yourself now by following the instructions. In brief:

• On the command line, type:

  $ pfexec pkg install SUNWgmake SUNWj6dev SUNWant sunstudioexpress SUNWcups SUNWzip SUNWunzip SUNWxwhl SUNWxorg-headers SUNWaudh SUNWfreetype2

  to install the build dependencies.
• Set a handful of environment variables:

  $ export LANG=C PATH="/opt/SunStudioExpress/bin:${PATH}" ALT_COMPILER_PATH=/opt/SunStudioExpress/bin/ ALT_DEVTOOLS_PATH=/usr/bin ALT_CUPS_HEADERS_PATH=/usr/include/

• Kick off the build:

  $ gmake

• When the build finishes, the binaries will be in the

  build/solaris-i586/j2sdk-image

  subdirectory.
