And why? There is a bootstrap process and compiling the real compiler process, but which part开发者_JS百科 consumes the most time?From the Gentoo perspective:
I have a Haskell program which processes a text file and builds a Map (with several million elements). The whole thing can run for 2-3 minutes. I found that tweaking the -H and -A options makes a big
Not a programming question, 开发者_开发问答but the first time I see something like this. UNR 1.6 (based on Ubuntu 10.04) installs the 6.12.1 version of GHC.

When compiling my Haskell application with the -Wall option, GHC complains about orphaned instances, for example:
I ported a little Haskell program I wrote from Mac to Windows. It\'s a GUI application (wxHaskell, compiled with ghc 6.12.1), so it does not need the command prompt window to open. It does so, anyway,
I\'ve tried this: main = do hSetBuffering stdin NoBuffering c <- getChar but it waits until the enter is pressed, which is not what I want. I want to read the character immediately after user p

I\'m getting a warning from GHC when I compile: Warning: This binding for \'pats\' shadows an existing binding in the definition of \'match_ignore_ancs\'
I\'m a beginner Haskell programmer. I have written some useful code for the last six month. And I want to release a lib开发者_运维知识库rary from it. The code will use system installation cabal as any
