Replacing module Array by IArray
by andreas.marth＠daimlerchrysler.com 04 Apr '01

04 Apr '01

Hallo! The module Array exports module Ix (Haskell 98 Library Report). The module IArray doesn't export Ix (jet?). I think a pack and unpack function to convert between IArray ix be and UArray ix ube via 'amap pack/unpack' would be useful. (Or am I just missing the conversion function and it is already there?

AW: Difficulties compiling hmake / HaXml

I recognized that in src/interpreter/Makefile there was still a reference to the posix package: HFLAGS = $(shell $(LOCAL)fixghc $(GHCSYM) -fglasgow-exts \ -package lang -package util -package posix $(READLINE) ) After removing "-package posix" and applying the change you mentioned, the compilation of hmake works now! Many thanks!! - Now I may try to go on with building the HaXml tools. Christian

function over Array and UArray possible?
by andreas.marth＠daimlerchrysler.com 29 Mar '01

29 Mar '01

Hallo! Is it possible to give a context, so that a function can have a signature which combines foo :: (Ix i) => Array i a -> Array i a and foo :: (Ix i) => UArray i a -> Uarray i a ? at the moment I have a lot of functions foo and fooU which have the same body but different type signatures. Thanks for any comments, Andreas

I tried to change the "configure" file as you described -- and after "./configure" and "make" I still get the same error message (see above). What can I do now? Is there another way to use HaXml on Win/Cygwin with GHC?

The flag you need to set is RtsFlags.GcFlags.maxHeapSize, which is in units of BLOCKs (i.e. divide by BLOCK_SIZE). Look in fptools/ghc/compiler/parser/hschooks.c for examples. Cheers, Simon

changing maximum heap
by andreas.marth＠daimlerchrysler.com 28 Mar '01

28 Mar '01

Hallo! I need to change the maximum heap to run a program. I know that I can call my program with the -M option (e.g. myProgram +RTS -M120m -RTS). But in section 3.12.4 of the user guide are some hooks named, which allow one to change different defaults. Unfortunatly I didn't find a Hook that enables me to increase the heap. Is there such a hook? And how do I have to use it? Any other alternatives? Thanks, Andreas

Okay, I tried to ignore the error and went on with "make install" (after "./configure" and "make"). However, again an error message appears (see above), and there is no .exe output. What can I do about this now?

If you have GHC 4.08.2, then you already have HaXML :-) It's in -package text.

Seems to be a recursive problem ... I thought I need hmake for building them. Or is there a way to do it without hmake? (But never mind, I think I can wait for the updated InstallShield.)
