For the meantime, are the HaXml tools' binaries for Win available for download somewhere?

Difficulties compiling hmake / HaXml
by Lescher Christian 28 Mar '01

28 Mar '01

I want to use HaXml, and since hmake is required first, I'm currently trying to build hmake with GHC. Unfortunately "make" fails; I get the above errors message. What am I doing wrong here? I use GHC4.08.2 (InstallShield version) under WinNT4/Cygwin1.1.8. Christian make[1]: Entering directory `/test-hmake/hmake-2.02/src/interpreter' mkdir -p /test-hmake/hmake-2.02/targets/ix86-CYGWIN_NT-4.0/obj/interpreter /test-hmake/hmake-2.02/script/hmake -ghc HInteractive -d/test-hmake/hmake-2.02/t argets/ix86-CYGWIN_NT-4.0/obj/interpreter Fail: Can't find module Posix in .

ghc & hdirect on windows
by Saswat Anand 28 Mar '01

28 Mar '01

I am trying to install ghc and hdirect on windows. But I have failed miserably. Initially I was able to install and run ghc, but after failing to run hdirect examples i did some changes to environment settings, and now none of them work. I also tried reinstalling both. 1. If I do mount c: / then: ghc does not compile and finishes without any word. I have /usr/bin/bash.exe and /usr/bin/sh.exe. 2. If I do not mount c: / then: administrator@CF-POSTGRAD12 /cygdrive/c/ghc/ghc-4.08.1/bin $ls ghc ghc-4.08.1 hp2ps.exe perl.exe stat2resid administrator@CF-POSTGRAD12 /cygdrive/c/ghc/ghc-4.08.1/bin $ghc bash: ./ghc: No such file or directory In any case it does not run, Is there any other combinations :-( 1. I have copied the perl.exe that comes with ghc to /user/bin 2. I am using the right version of mingw. 3. I have set SHELL = /usr/bin/bash 4. I have scanned most of the mails in ths list. Please help. Thanx, Saswat

Compiling HDirect from CVS
by Mike Thomas 27 Mar '01

27 Mar '01

Hi all. I'm having a lot of trouble building the latest version of HDirect from CVS. After setting up per the instructions, adjusting "mk/config.mk" to substitute mingw for cygwin (avoids problems about the Posix library) and then typing make at the top level of fptools I get the link error below. If I go to the hdirect directory and type "make boot" followed by "make" the same problem occurs. I am using ghc 4.08.2 under Windows NT4 with the latest Cygwin setup. Is "_imp___timezone_dll" a Haskell DLL, a missing Mingw lib, or some kind of foot and mouth virus passed from the pure Scottish air to Australia's unseasonally warm shores via cvs? Cheers Mike Thomas. ------------------------------------------------------------------------ ==fptools== make boot - --unix - --no-print-directory -r; in file://d/public/cvsroot/fpt/ghc/utils/hsc2hs ------------------------------------------------------------------------ Creating Config.hs ... done. make INSTALLING=0 BIN_DIST=0 - --unix - --no-print-directory -r all /cygdrive/c/ghc/ghc-4.08.2/bin/ghc -package util -O -c Config.hs -o Config.o -osuf o /cygdrive/c/ghc/ghc-4.08.2/bin/ghc -package util -O -c KludgedSystem.hs -o Kl udgedSystem.o -osuf o C:/TEMP/ghc218.hc:297: warning: implicit declaration of function `_getpid' /cygdrive/c/ghc/ghc-4.08.2/bin/ghc -package util -O -c Main.hs -o Main.o -osu f o /cygdrive/c/ghc/ghc-4.08.2/bin/ghc -o hsc2hs-bin -package util -O Config.o KludgedSystem.o Main.o C:/ghc/ghc-4.08.2/lib/libHSstd.a(Time.o)(.text+0x1c42c):ghc1360.c: undefined ref erence to `_imp___timezone_dll' collect2: ld returned 1 exit status

I've put the GHC dists in ftp://www.haskell.org/pub/ghc, you should be able to download them from there. I don't know if it'll work with HP-UX 11.0, it was built on 10.20 with gcc 2.7.2.1. Also, gcc 2.95.2 is known not to work with GHC on HP-UX at the moment. Cheers, Simon

Question concerning ftp and GHC binaries for HP-UX
by ADAMS,RICHARD (Non-HP-Roseville,ex1) 21 Mar '01

21 Mar '01

I would like to download the GHC binaries to our HP 9000 machine (HP-UX 11.0), but have access only to ftp (i.e., no Web browser is available). Does anyone know what ftp address to use? Also, does anyone know whether the GHC binaries for the HP-UX operating system will work on HP-UX 11.0? I am not sure whether it is relevant, but I use Reflection terminal emulation to telnet from my PC to the HP 9000 machine. Truly 'hi-tech' :) . Thank you. Sincerely, Richard E. Adams Softmatrix, Inc.

Proposed change to ghc installation procedures
by Julian Seward (Intl Vendor) 20 Mar '01

20 Mar '01

Greetings, GHC users. If you install GHC from .rpm's, Debian .deb's, InstallShields, or other package formats, READ NO FURTHER. The following DOES NOT AFFECT YOU. The following applies ONLY if you install GHC from binary .tar.gz files. (Sparc-solaris users might, for example). As the GHC 5 release approaches, we're considering changing how binary builds of GHC are installed. The main aim of this proposal is to simplify parts of the GHC build system which have gotten a bit out of hand and are proving difficult to maintain as a result. The purpose of this message is to show the proposed changes and find out if it will cause problems for people. Up till now, the installation procedure (eg with 4.08.2) was gzip -dc ghc-4.08.2-my-platform-descriptor.tar.gz | tar xvf - cd ghc-4.08.2 ./configure --prefix=/where/ghc/should/be/installed make install The proposed new installation scheme is in fact a return to an old scheme: gzip -dc ghc-4.08.2-my-platform-descriptor.tar.gz | tar xvf - and then edit by hand ghc-4.08.2/bin/my-platform-descriptor/ghc5 to set the GHC_TOPDIR env variable to point to the top of the installation tree. So you run the distributed image in-place. The initial edit of the ghc5 script allows it to know where it is installed. This simplifies our build process; no longer do we need to create an installation-time Makefile or configure script and all its supporting junk. I assume that most users install from .rpms, so this change only affects package builders and sparc-solaris users. Please eeeep ASAP if this will cause you problems; otherwise we will go ahead with it in in the next couple of days. J

In particular, Linux will have a problem with thousands of *runnable* processes. There's some potentially nasty O(>n) complexities when processing the run queue, so while a couple of runnable processes is very fast, having lots is not. In practice, most processes are blocked on IO most of the time, so it seems it's only a problem for certain Java benchmarks. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
