The easiest way to install ISSM is to download the pre-compiled binaries. No need to compile the code, just open the compressed file.

Source Code

If you would like to install ISSM from source, you will need to download the source code first. The source code of ISSM (see License below) is available from an SVN repository. In order to fetch a version of the code, users will need to install SVN on their machine (It is usually installed by default on most platforms). Once SVN has been installed, ISSM can be downloaded by the following command:

$ svn --username anon --password anon checkout

This command will download the lastest version of ISSM from the repository, onto the current local directory. Users are free to choose whichever location they want.

If you downloaded the source code, you need to compile and install ISSM. Compilation of the ISSM source code is theoretically possible on any platform. It has been succesfully carried out on Linux (RedHat and ubuntu), Windows (9 and 10) and macOS (from snow-leopard to Sierra). Here are some instructions to compile and install ISSM from the source code:

Compilation is a more involved process, which is not recommended for beginners or casual users.
