config appears to have gone crazy
by Thomas Davie 28 Jul '05

28 Jul '05

Something appears to have blown up in configuring hat on my box... The release used to work, but I just checked out of cvs, built cleanly, and now get this when I try to run any of the tools: tatd2@jet ~/HatDeltaExample $ hat-observe /usr/local/bin/hat-observe: line 4: /usr/local/bin/harch: No such file or directory /usr/local/bin/hat-observe: line 5: /usr/local/lib/hat//hat-observe: No such file or directory /usr/local/bin/hat-observe: line 5: exec: /usr/local/lib/hat//hat- observe: cannot execute: No such file or directory It appears to have decided the architecture is '', rather than 'ix86- linux'. Any ideas? Bob

set Prelude modules as untrusted
by Kate Krastev 20 Jul '05

Hi there, Is it possible to set all/some Prelude modules to untrusted in Hat? (So I can see exactly what calls what) Thanks, Kate

Oddness...
by Thomas Davie 18 Jul '05

18 Jul '05

I've been trying to get hat-trans to eat QuickCheck, without much success. Is there something I'm missing? I'm getting this error: hat-trans QuickCheck.hs head: `-1 ' option is obsolete; use `-n 1' since this will be removed in the future hat-trans: Variable or constructor not in scope: chr Any ideas? I know Neil got it to work, so I'm guessing brain fart on my part. Bob

problem specifying location of imported module
by Terrence Brannon 04 Jul '05

04 Jul '05

Hello everyeone, My main file, ex6.hs, imports Pictures.hs: import Pictures import Data.Char {- .. bunch of code then main...-} main = putStrLn $ show (newHeight imgA imgB) It compiled to an executable and runs just fine: terry@Abulafia:~/haskell/craft-of-fp/ex$ hmake -i../Code ex6 /usr/bin/haskell-compiler -i../Code -o ex6 ../Code/Pictures.o ex6.o terry@Abulafia:~/haskell/craft-of-fp/ex$ ./ex6 32 terry@Abulafia:~/haskell/craft-of-fp/ex$ However, when I attempt to create an executable traceable by Hat, I have some problems: terry@Abulafia:~/haskell/craft-of-fp/ex$ hmake -hat -i../Code ex6 hat-trans -i../Code ../Code/Pictures.hs Creating directories Hat Hat/.. Hat/../Code Wrote Hat/../Code/Pictures.hs /usr/bin/haskell-compiler -i../Code -c -package hat -o ../Code/Hat/Picture\s.o ../Code/Hat/Pictures.hs ghc-6.2.2: error: directory portion of "../Code/Hat/Pictures.o" does not exist \(used with "-o" option.) Above it looks like the wrong directory was created. Hat created the directory Hat/../Code when I think it should have created the directory ../Code/Hat. At any rate, I went ahead and made the directory that the error complained did not exist and then re-ran, but still had errors: terry@Abulafia:~/haskell/craft-of-fp/ex$ hmake -hat -i../Code ex6 hat-trans -i../Code ../Code/Pictures.hs Wrote Hat/../Code/Pictures.hs /usr/bin/haskell-compiler -i../Code -c -package hat -o ../Code/Hat/Picture\s.o ../Code/Hat/Pictures.hs ghc-6.2.2: file `../Code/Hat/Pictures.hs' does not exist terry@Abulafia:~/haskell/craft-of-fp/ex$ Switching to absolute paths for the -i flag did not help and using -d/tmp to force all .o files to be created in one place did not help either. Any input on getting my entire program traceable is appreciated. If you care to look at ex6.hs or Pictures.hs, my entire haskell directory tree can be browsed by the web here: http://www.hcoop.net/~terry/haskell/craft-of-fp ex6.hs is here: http://www.hcoop.net/~terry/haskell/craft-of-fp/ex/ex6.hs and Pictures.hs is here: http://www.hcoop.net/~terry/haskell/craft-of-fp/ex/Code/Pictures.hs ======== As an afterthought, I tried making my project from the directory above both the main file and the imported file, but that failed as well: terry@Abulafia:~/haskell/craft-of-fp$ hmake -iCode ex/ex6 terry@Abulafia:~/haskell/craft-of-fp$ ex/ex6 32 terry@Abulafia:~/haskell/craft-of-fp$ hmake -hat -iCode ex/ex6 hat-trans -iCode Code/Pictures.hs Creating directories Hat Hat/Code Wrote Hat/Code/Pictures.hs /usr/bin/haskell-compiler -iCode -c -package hat -o Code/Hat/Pictures.o Code/Hat/Pictures.hs ghc-6.2.2: file `Code/Hat/Pictures.hs' does not exist terry@Abulafia:~/haskell/craft-of-fp$ Regards, -- Carter's Compass: I know I'm on the right track when, by deleting something, I'm adding functionality.

two minor bugs
by Matthias Neubauer 01 Jul '05

01 Jul '05

Dear hat team! I encountered two minor shortcomings after installing the latest hat release: - there seems to be a typo in the hattools Makefile - hat-trans does not seem to correctly recognize .lhs files Here is a simple "quick and dirty" fix for both problems: Regards, Matthias -- Matthias Neubauer | Universität Freiburg, Institut für Informatik | tel +49 761 203 8060 Georges-Köhler-Allee 79, 79110 Freiburg i.
