Hi all, We've been putting together a community build farm and have wrangled from ARM machines. We are building from jdk8u and have the following configuration:
----- A new configuration has been successfully created in /home/jenkins/workspace/george_arm_test/openjdk/build/linux-aarch64-normal-server-release using configure arguments '--with-boot-jdk=/usr/lib/jvm/java-1.7.0-openjdk-arm64 --enable-ccache --with-jvm-variants=server --with-cacerts-file=/home/jenkins/workspace/george_arm_test/cacerts_area/security/cacerts --with-alsa=/home/jenkins/workspace/george_arm_test/alsa-lib-1.0.27.2 --with-freetype=/home/jenkins/workspace/george_arm_test/openjdk/installedfreetype --with-x=/usr/include/X11 --with-debug-level=release'.
