1.3. 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

./configure --prefix=/usr/local
make
sudo make install
sudo ldconfig
sudo ldconfig /usr/local/lib64

1.4. Set Environment Variables

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

1.5. Download and Install Scala

cd $SOURCE_ROOT
wget https://github.com/lampepfl/dotty/releases/download/3.3.4/scala3-3.3.4.tar.gz
tar -xvf scala3-3.3.4.tar.gz
export PATH=$SOURCE_ROOT/scala3-3.3.4/bin:$PATH

Check Scala version by using the following command

scala -version
scalac -version
Scala code runner version 3.3.4 -- Copyright 2002-2024, LAMP/EPFL
Scala compiler version 3.3.4 -- Copyright 2002-2024, LAMP/EPFL

2. Testing Scala Sample Program (Optional)

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!
