c2hs is a pre-processor for Haskell FFI bindings to C libraries
c2hs is a interfacing tool that eases Haskell access to C libraries.
The tool gets information about the C data type definitions and
function signatures by analysing the C header files of the library.
It uses this information to compute the missing details in the
template of a Haskell module — called the binding file —
that implements a Haskell binding to the C library. Hooks embedded in
the binding file signal where, which, and how C objects are accessed
from Haskell. The Haskell code in the binding file determines Haskell
types signatures and marshaling details.
Further information is on the
wiki. Also see the
user guide (also
available in the doc directory of the repository).
Installing
To install c2hs from Hackage:
cabal install c2hs
If you like to build from the GitHub repository, see the file
INSTALL. See the REGRESSION-SUITE file for a description of how
to run the regression suite for checking C2HS performance against
existing Haskell packages that use it.
License
All code generated by c2hs is under a BSD licence. Hence, c2hs is useful for both open and closed source projects.
The tool itself is released under the GPLv2. This is the same situation as for the GNU C Compiler. For details, see the file COPYING.
