Example C program, showing to to call Haskell shared libraries. Also demonstrates how to build a dynamically- and statically-linked Haskell shared library.

Usage

$ make test
...
PASS

Dynamic

Entrée: A shared library with a pure Haskell centre, linked with dynamic Haskell libraries.

$ make dynamic-build
...
$ make dynamic-test
...
Testing dynamic flavour
  Simple test:    PASS
  Threaded test:  PASS

Static

Plat principal: A shared library with a pure Haskell centre, linked with static Haskell libraries.

$ make static-build
...
$ make static-test
...
Testing static flavour
  Simple test:    PASS
  Threaded test:  PASS

Note: On Linux, the static flavour requires rebuilding GHC packages as position-independent code.
