passing an option to gcc without a -
by Hal Daume III 25 Jul '02

I'm linking with a .a file built from C; when I do this on a C program I do something like: gcc myfile.c -o myout theafile.a so i tried ghc MyFile.hs -o myout -optctheafile.a but this doesn't appear to pass the paramter. when i run with -v3 and inspect the call to gcc it doesn't include this option. if i copy that call to gcc and add it maually at the command line, everything's cool thoughts? - hal -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

Hmm, I tried quite hard not to break too much stuff in 5.04. That's why all the old hslibs are still there, and they still supply virtually the same APIs that they did in 5.02.

A > minor version change should not break programs (imo). 5.02->5.04 is a major version change :-) We only promise not to break APIs in patchlevel releases (eg. 5.04->5.04.1 won't break anything). > Sorry for the tirade, but I'm pressured to get some code out > soon and this isn't helping things. Not at all, we appreciate the feedback. I'm surprised that you're having so much trouble though. Cheers, Simon

RE: Using UArray and Array

> Short answer: just say > > import Array(Array) > import Data.Array.Unboxed I'd prefer it if Data.Array was the fully overloaded version, but sadly IArray requires multi-param type classes and we don't want to knobble the libraries too much for non-MPTC compilers. The current situation is a bit unsavoury, though; perhaps Data.Array.IArray should re-export the Array type. Cheers, Simon

Foreign.destructArray
by Hal Daume III 24 Jul '02

what happened to Foreign.destructArray? I can't seem to find it anywhere... Also, has anyone thought of putting a search-engine front end on to the Haskell documentation? Even just a search on google using site:haskell.cs.yale.edu filetype:html inurl:docs would be nice, once google decides to index the new docs :). a closer integration would be nice though... - hal -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

The doc RPM package for Red Hat 7.3 suffers the same problem as the SuSE one. Could someone please give a hand-holding guide so that we can fix it ourselves? Please? Please?

suggestion regarding :browse
by Hal Daume III 24 Jul '02

24 Jul '02

if we have import qualified Some.Long.Module.Name as N we can do :info N.somefunction or :info Some.Long.Module.Name.somefunction and :browse Some.Long.Module.Name but not :browse N which would be really nice :P if this could make its way into 5.04.1, that would be wonderful -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

Using UArray and Array
by Ken T Takusagawa 24 Jul '02

24 Jul '02

I'm having difficulty compiling under 5.04 using both Arrays and UArrays: module Main where{ import Array; import Data.Array.Unboxed; array_1::UArray(Int)(Int); array_1 = (array (1,3) [(1,7),(2,8),(3,13)]); array_2::Array(Int)(Int); array_2 = (array (1,3) [(1,700),(2,800),(3,1300)]); main::IO (); main = putStrLn "hi world" } This gets me the errors Ambiguous occurrence `array' It could refer to either `Data.Array.Base.array', imported from Data.Array.Unboxed at arrayfailx.hs:6 or `GHC.Arr.array', imported from Array at arrayfailx.hs:5 Suggestions? (I would rather not have to fully qualify every occurence of array, accumArray, and ! in my program.) Ken Takusagawa

Use hPutBufBA instead. BTW, Haddock has a version of the Binary module which works with GHC 5.04. Cheers, Simon
