Building Scala

Below versions of Scala are available in respective distributions at the time of creation of these build instructions:

  • Ubuntu 20.04 has 2.11.12-4
  • Ubuntu (22.04, 22.10, 23.04) has 2.11.12-5
  • RHEL (8.6, 8.7, 8.8) has 2.10.6

The instructions provided below specify the steps to build Scala version 3.3.0 on Linux on IBM Z Systems for following distributions:

  • RHEL (7.8, 7.9, 8.6, 8.7, 8.8, 9.0, 9.1, 9.2)

  • Ubuntu (20.04, 22.04, 22.10, 23.04)

General Notes:

  • When following the steps below please use a standard permission user unless otherwise specified.
  • A directory /<source_root>/ will be referred to in these instructions. This is a temporary writable directory anywhere you'd like to place it.

Note: At the time of creation of these build instructions, Scala 3.3.0 was verified with
OpenJDK 1.8.0, 11.0.19, 17.0.7
IBM Semeru Runtime Open Edition 1.8.0_372-b07, 11.0.19.0 and 17.0.7.0
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_282-b08)
Eclipse Adoptium Temurin-11.0.19+7, Temurin-17.0.7+7

1.2) Build libffi library (For AdoptOpenJDK8 on Ubuntu, SLES and RHEL 9.x)

cd $SOURCE_ROOT/
wget ftp://sourceware.org/pub/libffi/libffi-3.2.1.tar.gz
tar xvfz libffi-3.2.1.tar.gz
cd libffi-3.2.1
./configure --prefix=/usr/local
make
sudo make install
sudo ldconfig
sudo ldconfig /usr/local/lib64

1.3) Set Environment Variables

export JAVA_HOME=<Path to Java>
export PATH=$JAVA_HOME/bin:$PATH

1.4) Download and Install Scala

cd $SOURCE_ROOT
wget https://github.com/lampepfl/dotty/releases/download/3.3.0/scala3-3.3.0.tar.gz
tar -xvf scala3-3.3.0.tar.gz
export PATH=$SOURCE_ROOT/scala3-3.3.0/bin:$PATH

Check Scala version by using the following command

scala -version
scalac -version
Scala code runner version 3.3.0 -- Copyright 2002-2023, LAMP/EPFL
Scala compiler version 3.3.0 -- Copyright 2002-2023, LAMP/EPFL

Step 2: [Optional] Testing Scala Sample Program

2.1) Create a test program

Create a test file called Hello.scala using below command:

echo '@main def hello = println("Hello, world!")' > Hello.scala

2.2) Compile the test program

scalac Hello.scala

Note: This will create several files:

Hello$package$.class
Hello$package.class
Hello$package.tasty
Hello.scala
hello.class
hello.tasty

2.3) Execute the test program

scala hello

The output of the above test program should be:

Hello, world!
