Requirements

Java environment

Since NoiseModelling is developped with the Java langage, you will need to install the Java Runtime Environment (JRE) on your computer to use the application.

Warning

Only version 11.x of Java is compatible with NoiseModelling 4.x

Windows

If you are launching NoiseModelling thanks to the NoiseModelling_xxx_install.exe file, the JRE is already inside, so you don’t have anything to do.

If you are not using the .exe file, you have to launch NoiseModelling thanks to the `...\bin\startup_windows.bat file (in the NoiseModelling_xxx.zip release file). In this case, Java v11.x has to be installed before.

  1. Download and install Java: choose between OpenJDK or Oracle versions.
  2. You can check if JAVA_HOME environnement variable is well settled to your last installed Java folder using echo %JAVA_HOME% in your command prompt. You should have a result similar to C:\\Program Files (x86)\\Java\\jre1.8.x_x\\.
  3. If you don’t have this result, it is probably because your JAVA_HOME environnement variable is not well settled. To set you JAVA_HOME environnement variable you can adapt (with x the JAVA version number) you installed and use the following command line : setx JAVA_HOME  "C:\\Program Files (x86)\\Java\\jre.1.8.x_x" in your command prompt. You can also refer to this document for example.
  4. You may have to reboot your command prompt after using the precedent command line before printing again echo %JAVA_HOME%.

Warning

The command promprt should print C:\\Program Files (x86)\\Java\\jre1.11.x_x\\ whithout the bin directory. If JAVA_HOME is settled as C:\\Program Files (x86)\\Java\\jre1.11.x_x\\bin, it will not work. It should also point to a JRE (Java Runtime Environment) Java environnement and not JDK.

Linux or Mac

If not already done, you have to install the Java version v11.x.

  1. Download and install Java: choose between OpenJDK or Oracle versions.
  2. You can check if JAVA_HOME environnement variable is well settled to your installed v11.x Java folder using echo $JAVA_HOME in your command prompt. You should have a result similar to /usr/lib/jvm/java-11-openjdk-amd64/.
  3. If you don’t have this result, it is probably because your JAVA_HOME environnement variable is not well settled. In this case, you are invited to follow the steps proposed here.
  4. Once done, you may have to reboot your command prompt (or maybe disconnect/reconnect your session) after using the precedent command line before printing again echo $JAVA_HOME.
