and I say this as someone who's spent time before and around the 7.4 and

Yes, exactly this.

hi all,
I've added some code [1] [2] to GHCJS to make
This would probably be a great boon for those trying to use haskell for
Android and IOS right? how might the emulation setup work for those?

If theres a clear path to getting
=org.metasepi.ajhc.android.cube
this was made with Kiwamu's ajhc branch but code has been merged back
into the main tree.

could you share the output of ghc --info?

i assume 7.6 and 7.8, if we're talking GHC rather than GCC :)
in 7.8 you can't define userland typeable instances, you need only write
deriving (Typeable) and you're all set.
add some CPP to select the instances suitable

more concretely
#if defined(__GLASGOW_HASKELL__) ( __GLASGOW_HASKELL__ = 707)
--- do the deriving version here
#else
--- your current stuff
#endif

So you need to be able to change
if your computation in the C call takes more than 400 nano seconds, the
overhead of the safe ffi convention is less onerous and you should do that
when applicable.
an alternative is so use forkOn to setup a worker thread on various GHC
capabilities, and have them in parallel work on different
have a smart wrapper around you ffi call, and if when you think the ffi
call will take more than 1 microsecond, ALWAYS use the safe ffi call,
i do something like this in an FFI i wrote, it works great

actually a great idea, especially since the safe variants of the
calls are already in place.

i personally think the .format+lhs pattern/convention is a good one, and
prevents any misinterpretations that current plague literate tools + willl
be treated as an unknown format rather than eagerly as .format or .lhs

You need to pass cabal the extra includes and extra lib dirs flags with the
explicit paths to the lib and include folders that have your blas and
lapack. The logic in hmatrix can only check stadard paths.

Hi,
Yes,
What Linux distro? If you're on an unusual distro You might just need to
patch the build process to look up the right names.
Also have you contacted the hmatrix maintainer to ask him for help. HMATRIX
does have an issue tracker on github etc
