This is the (work in progress) SunOS jdk builder.
The aim is to attempt to download, patch, and build any relevant jdk tag, and do so for SPARC and x86, and for illumos and Solaris 11.4. It has currently been spot-tested on current illumos/x86 (specifically Tribblix m32).
It is dependent on the jdk-sunos-patches repository, which holds all the patches for each tag.
It should simply be a case of uttering
./dobuild jdk17u-jdk-17.0.8-ga
Look in the "jdk-sunos-patches" repository for the list of known versions.
Unless you're developing a new port, or bisecting a bug, generally the latest version of a given release (which will probably be one of the update releases, ie jdkXXu) ought to be a good place to start. For example:
jdk11u-jdk-11.0.20-ga
jdk12u-jdk-12.0.2+10
jdk13u-jdk-13.0.14-ga
jdk14u-jdk-14.0.2-12
Are all supposed to be supported; later versions need the more extensive patches available as part of this project.
Generally, you need to have a functioning build of one version of the jdk to build the next version. One point of this project is to allow you to build the whole chain from source.
Some systems already have the required jdk versions available, in
/usr/jdk/instances. Others do not. For those, you'll need to install
a successful build in order to move on. So, the command
./dobuild -i jdk12u-jdk-12.0.2+10
will make that version of jdk12 available, ready for the jdk13 build.
To use a Liberica build (which would be a jdk11 release) give the absolute path to where it was unpacked, for example
./dobuild -i /path/to/jdk-11.0.18
First decide on a directory tree where you're going to keep the code and run the builds. Then set the variables THOME and BUILDROOT in your environment to point to them, and create them. For example
THOME=/var/tmp/java
mkdir -p $THOME
BUILDROOT=/var/tmp/java-build
mkdir -p $BUILDROOT
Then checkout the two repositories from github:
cd $THOME
git clone https://github.com/ptribble/jdk-sunos-builder
git clone https://github.com/ptribble/jdk-sunos-patches
You'll also need to install some software in order for the builds to work.
Install the following overlays:
zap install-overlay openjdk-build
zap install-overlay java8
zap install-overlay java11
zap install-overlay java17
zap install openjdk12 openjdk13 openjdk14 openjdk15 openjdk16
zap install openjdk18 openjdk19 openjdk20 openjdk21
I'm assuming you're using the Solaris 11 CBE, which already has most of the development toolchain preinstalled. But you will need:
pkg install pkg:/developer/gcc-7
pkg install pkg:/system/font/truetype/dejavu
pkg install pkg:/developer/versioning/git
pkg install pkg:/developer/build/autoconf
And you'll need to download a Java 11 JDK to start from - use the Liberica JDK.
On other illumos distributions you'll need to ensure you have a complete developer toolchain and as many versions of java as are available in that distribution.
More extensive documentation is available, to help you through the general porting process.
