Sundials Types Part I #71
Description
I am trying to use sundials via inline-c. I am starting to define the types some of which are quite complex :( Even the simplest seems to throw up problems. For example what should I do here?
#if defined(SUNDIALS_INT64_T)
#if __STDC_VERSION__ >= 199901L
typedef int64_t sunindextype;
#else
typedef long int sunindextype;
#endif
#elif defined(SUNDIALS_INT32_T)
#if __STDC_VERSION__ >= 199901L
typedef int32_t sunindextype;
#else
typedef int sunindextype;
#endif
#endif
At the moment I have this
-- This is a lie!!!
type SunIndexType = CLong
sunTypesTable :: Map.Map CT.TypeSpecifier TH.TypeQ
sunTypesTable = Map.fromList
[
(CT.TypeName "sunindextype", [t| SunIndexType |] )
]
sunctx = mempty {ctxTypesTable = sunTypesTable}

Ah but maybe I don't need to do this anyway.

@idontgetoutmuch how did you resolve this?

I don't think I did resolve that particular issue but it's all working - see here: https://github.com/haskell-numerics/hmatrix-sundials/blob/master/src/Numeric/Sundials/Arkode.hsc

My best work around for this sort of issue is to use
hsc2hsandinline-cin the same Haskell module.With
hsc2hsyou can useand then the rest of your code is correct.
