The nhc98 compiler

nhc98 is a small, easy to install, standards-compliant compiler for Haskell 98, the lazy functional programming language. It is very portable, and aims to produce small executables that run in small amounts of memory. It produces medium-fast code, and compilation is itself quite fast. It also comes with extensive tool support for automatic compilation, foreign language interfacing, heap and time profiling, tracing, and debugging. (Some of its advanced kinds of heap profiles are not found in any other Haskell compiler.)

The nhc98 webpages have moved to http://haskell.org/nhc98/.
