## build Graal as jvmci vm, i.e., with graal-core as top tier compiler
cd graal-core
../mx/mx --vm jvmci build

## build JRuby
cd ../jruby
## mvn might need JAVA_HOME:  export JAVA_HOME=$(/usr/libexec/java_home)
./mvnw

## run Richards
cd ../are-we-fast-yet/benchmarks/Ruby

## JDK version number might differ below
