Welcome to LabsJDK CE 11.

The latest release is available at https://github.com/graalvm/labs-openjdk-11/releases/latest

This is a fork of https://github.com/openjdk/jdk11u-dev (which is a read-only mirror of https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/) that exists for the purpose of building a base JDK upon which GraalVM CE 11 is built.

It can be built with:

python build_labsjdk.py

This will produce a labsjdk installation under build/labsjdks/release along with 2 archives in the same directory; one for the JDK itself and a separate one for the debug symbols.

You can pass extra options to the configure script using --configure-option or --configure-options. For example:

--configure-option=--disable-warnings-as-errors --configure-option=--with-extra-cxxflags=-fcommon --configure-option=--with-extra-cflags=-fcommon

or alternatively:

--configure-options=my.config

where the contents of the file my.config are:

--disable-warnings-as-errors
--with-extra-cxxflags=-fcommon
--with-extra-cflags=-fcommon

You can verify the labsjdk build with:

./build/labsjdks/release/java_home/bin/java -version
