Haskell interface to Gibbs-SeaWater (GSW) Oceanographic Toolbox. Previous versions were interface to FORTRAN toolbox, but from version 2.0.0.0, this Haskell version uses the C toolbox. The latest version of the C toolbox at the time of writing is 3.05.0-4. If a different version is to be used, it might be necessary to tweak Oceanogr/GSWtools.chs.
Download the C version of the GSW Toolbox. Usually the latest from Github repo is newer than official repo. Install in your favourite directory $(LIB).
% cd $(LIB)
% git clone https://github.com/TEOS-10/GSW-C.git
% mv GSW-C gsw_c_v3.05_0-4
If you do not have a Python environment, apply the following patch to avoid loosing gsw_chec_data.c.

It's a good idea to test the C version.
% cd gsw_c_v3.05_0-4
% ./gsw_check
The interfaces (i.e. foreign imports) are automatically generated from Oceanogr/GSWtools.chs by c2hs. The attached version is for GSW C version 3.05. It might be necessary to modify Oceanogr/GSWtools.chs if different version is to be used.
Before compiling, modify include-dirs and extra-lib-dirs in GSW.cabal. Note that the paths must be absolute (issue with cabal). If the C library in
ghc-options: -optl-Wl,-rpath,$(LIB)/gsw_c_v3.05/
entry in the GSW.cabal file. Then,
% stack install
will install the library.
