Is it possible to compile Haskell code targetting a OS/arch that
differs from the one where the compiler (GHC) is running?
No, GHC doesn't currently support
Hi. I need map equivalent for Bijection type which is defined in fclabels:
data Bijection (~) a b = Bij { fw :: a ~ b, bw :: b ~ a }
instance Category (~) = Category (Bijection (~)) where ...
I can define this function as follows:
mapBij :: Bijection (-) a c - Bijection (-) [a] [b] - Bijection
If you remove the second argument (which you don't use), you have the
function `liftBij` that is in fclabels.

For a caching library, I need to know the runtime usage of memory of the
program and the total amount of memory, the total memory used by all the
programs etc.
I need not do profiling or monitoring but to do different things inside my
program depending on memory usage.
The search is difficult
Yes, you are right, I don't really need the second argument. I am not
skilled enough to join the discussion, but I do understand your
solution. Thanks!

Hang on a second.
The reason you're seeing build breakage is that the .cabal files of the
broken packages were edited in-place without
Hi,
Here is a simple shell script (upper.hs):
import Data.Char
main = interact $ map toUpper
which composes fine with other scripts:
bash-3.2$ yes | head -n 3 | runghc upper.hs
Y

but not always:
bash-3.2$ yes | runghc upper.hs | head -n 3

Hello,
this happens because head probably closes the file descriptor after 3
lines, and then the Haskell program tries to write to a closed handle
(i.e., it's stdout is not there anymore). The best thing to do depends on
the program. One fairly simple option would be to handle the exception, and

This is probably best referred to as a Haskell script.

Thanks Brandon and Iavor for your (fast!) responses.
Installing a silent handler as suggested by Brandon worked nicely.

Well, this one looks like it was my fault because I never read this thread
and this morning I uploaded that package (abstract-deque) with the
conditional in the test-suite. The reason this conditional isn't there now
is that the package was hacked in place to remove tests, which is fine.
