README:
This file should be located at the top of the OpenJDK Mercurial root
repository. A full OpenJDK repository set (forest) should also include
the following 7 nested repositories:
"jdk", "hotspot", "langtools", "nashorn", "corba", "jaxws" and "jaxp".
The root repository can be obtained with something like:
hg clone http://hg.openjdk.java.net/jdk9/jdk9 openjdk9
You can run the get_source.sh script located in the root repository to get
the other needed repositories:
cd openjdk9 && sh ./get_source.sh
People unfamiliar with Mercurial should read the first few chapters of
the Mercurial book: http://hgbook.red-bean.com/read/
See http://openjdk.java.net/ for more information about OpenJDK.
Simple Build Instructions:
0. Get the necessary system software/packages installed on your system, see
http://hg.openjdk.java.net/jdk9/jdk9/raw-file/tip/README-builds.html
1. If you don't have a jdk8 or newer jdk, download and install it from
http://java.sun.com/javase/downloads/index.jsp
Add the /bin directory of this installation to your PATH environment
variable.
2. Configure the build:
bash ./configure
3. Build the OpenJDK:
make all
The resulting JDK image should be found in build/*/images/jdk
where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
is 3.81 or newer. Note that on Solaris, GNU make is called "gmake".
