Building OpenJDK using temurin build scripts within the adopt build docker container

1. Pull the build docker image for your environment:

For a x64 architecture use docker image: docker pull adoptopenjdk/centos6_build_image

For a arm64 architecture use docker image: docker pull adoptopenjdk/centos7_build_image

2. Create a local workspace to build in:

mkdir workspace

3. Start docker container, substitute full path to workspace:

docker run -it -u=$(id -u):$(id -g) -w /..path../workspace -v /..path../workspace:/..path../workspace <image from (1)> bash

Note: If you have SELinux enabled (check with sestatus), then use -v /..path../workspace:/..path../workspace:z

4. git clone https://github.com/adoptium/temurin-build.git
5. cd temurin-build
6. Set the following environment variables, put into a script and source to make easier. Choose settings appropriate to your required arch, target, variant and version to build..:

export ARCHITECTURE=x64

export TARGET_OS=linux

export VARIANT=temurin

export JAVA_TO_BUILD=jdk17u

#export BUILD_ARGS= for any build args

#export CONFIGURE_ARGS= for any openjdk configure args

7. Perform build with command:

build-farm/make-adopt-build-farm.sh
