nhc98 is a compiler for the complete Haskell'98 language.

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.) It supports the new common primitive FFI (Foreign Function Interface), and includes the most advanced space-profiling facilities of all Haskell implementations. Most importantly, it allows graphical debugging of programs using both Hat and HOOD. nhc98 is available for all 32-bit Unix-like platforms. Although it is itself written in standard Haskell 98, it can be quickly and easily be bootstrapped from C sources, so you do not need another Haskell compiler to get started.
