ANNOUNCE: GHC version 6.4.1
by Simon Marlow 23 Sep '05

23 Sep '05

============================================================= The (Interactive) Glasgow Haskell Compiler -- version 6.4.1 ============================================================= The GHC Team is pleased to announce a new patchlevel release of GHC. This release contains a significant number of bugfixes relative to 6.4, so we recommend upgrading. No library APIs have changed, so code that was working with 6.4 should continue to work with 6.4.1. Release notes are here: http://haskell.org/ghc/docs/6.4.1/html/users_guide/release-6-4-1.html How to get it ~~~~~~~~~~~~~ The easy way is to go to the WWW page, which should be self-explanatory: http://www.haskell.org/ghc/ We supply binary builds in the native package format for various flavours of Linux and BSD, and in Windows Installer (MSI) form for Windows folks. Binary builds for other platforms are available as a .tar.gz which can be installed wherever you want. The source distribution is also available from the same place. Packages will appear as they are built - if the package for your system isn't available yet, please try again later. Background ~~~~~~~~~~ Haskell is a standard lazy functional programming language; the current language version is Haskell 98, agreed in December 1998 and revised December 2002. GHC is a state-of-the-art programming suite for Haskell. Included is an optimising compiler generating good code for a variety of platforms, together with an interactive system for convenient, quick development. The distribution includes space and time profiling facilities, a large collection of libraries, and support for various language extensions, including concurrency, exceptions, and foreign language interfaces (C, whatever). GHC is distributed under a BSD-style open source license. A wide variety of Haskell related resources (tutorials, libraries, specifications, documentation, compilers, interpreters, references, contact information, links to research groups) are available from the Haskell home page (see below). On-line GHC-related resources ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Relevant URLs on the World-Wide Web: GHC home page http://www.haskell.org/ghc/ Haskell home page http://www.haskell.org/ comp.lang.functional FAQ http://www.cs.nott.ac.uk/~gmh/faq.html Supported Platforms ~~~~~~~~~~~~~~~~~~~ GHC supports the following platforms in this release: * x86 machines running Windows, common flavours of Linux, FreeBSD, OpenBSD, and NetBSD * x86_64 (aka amd64) machines running Linux * Macs running MacOS X * PowerPC machines running AIX or Linux * Sparc machines running Solaris. Ports to other platforms are possible with varying degrees of difficulty. The Building Guide gives a complete run-down of what ports work and how to go about porting to a new platform: http://www.haskell.org/ghc/docs/latest/html/building/building-guide.html Mailing lists ~~~~~~~~~~~~~ We run mailing lists for GHC users and bug reports; to subscribe, use the web interfaces at http://www.haskell.org/mailman/listinfo/glasgow-haskell-users http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs There are several other haskell and ghc-related mailing lists on www.haskell.org; for the full list, see http://www.haskell.org/mailman/listinfo/ Please report bugs using our SourceForge page at http://sourceforge.net/projects/ghc/ or send them to glasgow-haskell-bugs(a)haskell.org. GHC users hang out on glasgow-haskell-users(a)haskell.org. Bleeding edge CVS users party on cvs-ghc(a)haskell.org.

It affects certain tools and the package database. If you can't build docs on your machine (a common problem), then you can grab docs from another distribution and put them in yours. Cheers, Simon

If you have a distribution, I can add it to the 6.4.1 downloads. Cheers, Simon

You need to build the libraries before you can use this GHC to build a program. Cheers, Simon

GHC/Int.hc is not supposed to refer to int64ToIntegerzh_fast, because on a 64-bit machine there is no Int64# primitive type (it's the same as Int#). You might want to make sure that ghc/includes/ghcautoconf.h on the host machine is the right one - it should have been copied from the target machine. > I notices that the evil mangler was replaced after my build.

If that's true, it means the port is going to require more work. But I'd be surprised, because FreeBSD is using the same compiler toolchain as everyone else. Cheers, Simon

You should be able to build a simple Haskell program and run it, like so: $ cat >hello.hs main = putStrLn "hello world!" ^D $ $target/ghc/compiler/ghc-inplace hello.hs $ ./a.out hello world! > The next failure is at Control/Arrow.hc after reconfiguration in > hc-build: > > ==fptools== gmake all -wr; > in /data/home/wb/Haskell/fptools-amd64/ghc-6.4.1/libraries/base > ------------------------------------------------------------------------ > gcc -x c Control/Arrow.hc -o Control/Arrow.raw_s -S -O > -D__GLASGOW_HASKELL__=604 -O > -I/data/home/wb/Haskell/fptools-amd64/ghc-6.4.1/ghc/includes > -I/data/home/wb/Haskell/fptools-amd64/ghc-6.4.1/libraries/base/include > -I/data/home/wb/Haskell/fptools-amd64/ghc-6.4.1/libraries/unix/include > -I/data/home/wb/Haskell/fptools-amd64/ghc-6.4.1/libraries/parsec/include > -I/data/home/wb/Haskell/fptools-amd64/ghc-6.4.1/libraries/readline/inclu de > -I. `echo | sed 's/^$/-DSTOLEN_X86_REGS=4/'` Control/Arrow.hc: In > function `s39r_entry': > Control/Arrow.hc:25: error: `stg_ap_p_ret' undeclared (first use in > this function) > Control/Arrow.hc:25: error: (Each undeclared identifier is reported > only once > Control/Arrow.hc:25: error: for each function it appears in.) > Control/Arrow.hc: In function `s39v_entry': > Control/Arrow.hc:46: error: `stg_ap_p_ret' undeclared (first use in > this function) ... Just to confirm - this is at the stage after "*** Building libraries..." in hc-build? I don't think the reconfigure step has worked properly. It still seems to be attempting to compile the .hc file, when in fact it should be using ghc-inplace to compile the .hs file. Check that mk/config.mk has BootingFromUnregisterisedHc=NO and BootingFromHc=NO. Cheers, Simon

Profiling works in 6.4.1 just like it has in previous versions. What is missing is profiling support in Cabal as shipped with 6.4.1, which is what I thought you were asking for. Newer versions of Cabal support profiling, and all you have to do is upgrade Cabal. Cheers, Simon

It's possible, but unlikely that we'll do it. It requires porting the required changes from the new Cabal version to the old version witout changing any library APIs. Of course, if someone were to send us a patch... Cheers, Simon

Garbage collecting CAFs
by John Meacham 20 Sep '05

20 Sep '05

I have seen numerous references to CAFs not used to being garbage collected in ghc leading to various contortions of the optimizer to keep from generating them and possible space leaks... then "something" was done and they are now collected.. I am curious what paper (or list message?) describes what that "something" is and what it entails in terms of tradeoffs. thanks. John -- John Meacham - ⑆repetae.net⑆john⑈

Hi, GHC 6.4.1 is now available for OS X via the darwinports system. The compiler is built from source, using a binary bootstrap compilier. Both 10.3 (Panther) and 10.4 (TIger) are supported. For more information on darwinports, see: http://darwinports.opendarwin.org Best Wishes, Greg Gregory Wright Antiope Associates LLC gwright(a)antiope.com
