I went ahead and implemented --print-hsc-options to jhc, which will spit
out something like '-I/usr/share/jhc-0.5/include' suitable for passing
to the hsc2hs command line. It seemed like the most straightforward
route of the choices mentioned.

The hsc2hs repo includes a shell script (yes, I know, no good on Windows)
called hsc2hs.wrapper that already adds some default arguments.
(nhc98 has a modified version of the script,
Q: is the information that --print-libdir returns available programmatically
to Haskell code?
$ ghc --print-libdir
C:\ghc\ghc-6.11.20090118

"C:\\ghc\\ghc-6.11.20090118"
$ ghc -e ':browse GHC.Paths'

Hi Ian,
it may encompass some of your suggested approaches below, but have
you considered either:
- add "--print-hsc-options" to the GHC driver, which is akin to
"--print-libdir". A ghc-installed hsc2hs shell wrapper or as you
suggest have 'hsc2hs' probe the compiler it is using would then
Hi all,
Currently, hsc2hs (as shipped with GHC) cannot be used with just
hsc2hs Foo.hsc
as it cannot find HsFFI.h (http://hackage.haskell.org/trac/ghc/ticket/2897).
To make it work you need to run something like
hsc2hs -I /usr/lib/ghc-6.10.1/include Foo.hsc
(it also works when called by C
