Hi all
I am confused by the GHC profiling output. I have put some abstracts
below to illustrate my confusion.
I compiled my code with:
HFLAGS=-Wall -package lang -prof -auto-all hmake -ghc main
and then ran it with:
./main -t +RTS -p test5.hs
Here is some of main.prof:
I'm trying to get to the point where I can use ghc and OpenGL under
Windows 2000. Unfortunately, I'm lost in a maze of version numbers.
I had cygwin-1.3.2 installed, I think, which did not match the 1.3.1
used in the ghc-4.08 package. I tried to install cygwin 1.3.1, but
got 1.3.3 instead.
Personally I think this is ok, and it's compatible with the
relaxed story about cumulative imports. I don't propose
to change this unless there are yells.

features of the language that make it killer in a particular application

Quick reply to just one point (more later, I hope):
Also, do these books have good coverage of things like
existential types, functional dependencies, other
experimental-but-apparently-crucial features that are hard to find
documentation for?

Thanks, that's very valuable information. It's hard to appreciate the

It's also confusing that things like exceptions, concurrency, and FFI are

No extensions whatsoever. (It even compiles and runs with all available

think GTK+ should be used mainly to develop applications which are intended
to run under GNOME and preferably not to do cross-plattform GUI programming.
I think the best solution for the latter thing is to use a library which has

Out of curiosity, how does GTK+ compare with Fruit?
It seems like it would make sense for the standard Haskell GUI also to be
functional.

PS I don't do GUI stuff so I don't really know much. I did read the Fruit
paper and it looked interesting.
