Installing SML/NJ under Windows

These instructions are for installing Standard ML of New Jersey (SML/NJ) as an application on Microsoft Windows. To use SML/NJ under the cygwin environment, see the installation instructions.

We provide a Microsoft Installer package for SML/NJ (https://smlnj.org/dist/working/110.96/smlnj-110.96.msi). The installer contains a full installation including nearly all of the optional components (it does not include "asdl", "mlrisc-tools", or "nowhere").

You can choose the installation directory. The default is C:\Program Files\SMLNJ. The bin directory containing the sml command is added to the default PATH, although you will need to re-open a command window to see the binding. The SMLNJ_HOME environment variable is also set to point at the location where SML/NJ was installed.

Once you have SML/NJ installed, you can launch the interactive top-level loop by selecting the application in the Start Menu. Alternatively, you can open a shell window and running the sml command.

To build SML/NJ from the runtime sources and precompiled "bin" files requires a Unix shell (we use Cygwin) to fetch and unbundle the files. In addition, you will need to have a version of Microsoft’s Visual Studio available.

To build the Windows installation, use the following steps. We have marked those steps that must be done in a Unix shell with a "[UNIX]" prefix and those that must be done in the Visual Studio shell with "[VS]".
