The Isabelle System Distribution

Version information

This is Isabelle-94 revision 8 as of May 1997. Basically, it should be backwards compatible to earlier Isabelle-94 releases. Older versions (like Isabelle-93) are quite different, though. See also the NEWS file in the distribution for a more detailed list of new features and changes.

System requirements

Isabelle requires a real Unix box with sufficient resources. Fun starts at about 32MB of memory (somewhat depending on your ML system), several tens of MB disk space and with a relatively fast CPU.

Furthermore, it needs the following software, which is not part of the distribution:

The ML system and GNU bash are absolutely essential. Perl is optional for core functionality, but still highly recommended.

The following ML system and platform combinations are known to work quite well:

Poly/ML is a commercial product and costs money, but it is stable and efficient. It requires relatively little memory (starting at about 16MB) and disk space (about 40MB for all distributed object logics).

SML/NJ needs lots of store and disk space, but it is free. The last official release is 0.93. Recent working versions may be better suited, under normal circumstances. Beware of the many incompatibilities among SML/NJ versions! From the 1.09.x family, we now only support 1.09.27, or later. An unofficial pre-built binary distribution of SML/NJ 1.09.27 for Linux is also available.

Installation

See file INSTALL in the Isabelle sources on how to build the system. Further background information may be found in the Isabelle System Manual, distributed as dvi with the sources.
