Re: [Haskell-cafe] Hint causes GHCi linker error under Windows
Hi Daniel, Do you have a complete example one can use to reproduce this behavior? (preferably a short one! :P) With this code I could reproduce it in ghci. runInterpreter $ loadModules [(SomeModule.hs, Nothing)] Currently I am not on a Windows machine, so I can't tell you if this only occured when trying to load a specific module. I'll try it later and if so, I'll tell you. If you need more information, just let me know. Martin The error message is: GHCi runtime linker: fatal error: I found a duplicate definition for symbol _hs_gtWord64 whilst processing object file C:\Programme\Haskell Platform\2009.2.0.2\ghc-prim-0.1.0.0 HSghc-prim-0.1.0.o This could be caused by: * Loading two different object files which export the same symbol * Specifying the same object file twice on the GHCi command line * An incorrect `package.conf' entry, causing some object to be loaded twice. GHCi cannot safely continue in this situation. Exiting now. Sorry. The problem does not occur under Unix or with a compiled program. IMHO hint tries to start a second instance of GHCi which is not allowed/possible under Windows. If this is the case a more telling error message would be helpful.

Initial ghc-6.12 + hackage build results
All, I've tried building 1324 out of the ~1700 packages from hackage using ghc-6.10.4 and ghc-6.12.0. This is the subset of packages that I could build in one go. Compared to the subset that I could build with ghc-6.10.4, I had to chuck out 125 packages because their build dependency constraints precluded them from building with ghc-6.12. Of the remaining 1324 packages, 113 packages that built OK previously now do not build. Amongst that 113, the ones that cause most knock-on failures are: (16,packedstring-0.1.0.1) (12,MissingH-1.1.0.1) (11,syb-with-class-0.5.1) (6,uvector-0.1.0.5) (3,stringtable-atom-0.0.6) (3,bindings-common-1.3.4) (3,binary-strict-0.4.6) (3,base64-string-0.1) packedstring fails because it needs base 4, but only says build-depends: base, so cabal uses its compatibility tricks and builds it against base 3. It should specify build-depends: base == 4.*. I need to investigate MissingH further. It failed because a dependency of its non-buildable test program was not found. That should not have been a problem. syb-with-class has type errors, I'm guessing due to changes in template-haskell package uvector does not compile because of the changes in GHC's Handle implementation. stringtable-atom now fails with a type error for reasons I don't quite understand: src/StringTable/AtomMap.hs:320:0: Occurs check: cannot construct the infinite type: a = (Int, a) When generalising the type(s) for `findMax' Perhaps some change in a containers function? bindings-common and c2hs fail because the CLDouble FFI type has been removed. binary-strict fails because the export of Control.Applicative.many now clashes with a local definition. base64-string fails because it sets -Werror in it's .cabal file (a practise which has been banned for some time for just this reason).

ANNOUNCE: GHC version 6.12.1
== The (Interactive) Glasgow Haskell Compiler -- version 6.12.1 == The GHC Team is pleased to announce a new major release of GHC. There have been a number of significant changes since the last major release, including: * Considerably improved support for parallel execution. GHC 6.10 would execute parallel Haskell programs, but performance was often not very good. Simon Marlow has done lots of performance tuning in 6.12, removing many of the accidental (and largely invisible) gotchas that made parallel programs run slowly. * As part of this parallel-performance tuning, Satnam Singh and Simon Marlow have developed ThreadScope, a GUI that lets you see what is going on inside your parallel program. It's a huge step forward from It takes 4 seconds with 1 processor, and 3 seconds with 8 processors; now what?. ThreadScope will be released separately from GHC, but at more or less the same time as GHC 6.12. * Dynamic linking is now supported on Linux, and support for other platforms will follow. Thanks for this most recently go to the Industrial Haskell Group who pushed it into a fully-working state; dynamic linking is the culmination of the work of several people over recent years. One effect of dynamic linking is that binaries shrink dramatically, because the run-time system and libraries are shared. Perhaps more importantly, it is possible to make dynamic plugins from Haskell code that can be used from other applications. * The I/O libraries are now Unicode-aware, so your Haskell programs should now handle text files containing non-ascii characters, without special effort. * The package system has been made more robust, by associating each installed package with a unique identifier based on its exposed ABI. Now, cases where the user re-installs a package without recompiling packages that depend on it will be detected, and the packages with broken dependencies will be disabled. Previously, this would lead to obscure compilation errors, or worse, segfaulting programs. This change involved a lot of internal restructuring, but it paves the way for future improvements to the way packages are handled. For instance, in the future we expect to track profiled packages independently of non-profiled ones, and we hope to make it possible to upgrade a package in an ABI-compatible way, without recompiling the packages that depend on it. This latter facility will be especially important as we move towards using more shared libraries. * There are a variety of small language changes, including * Some improvements to data types: record punning, declaring constructors with class constraints, GADT syntax for type families etc. * You can omit the $ in a top-level Template Haskell splice, which makes the TH call look more like an ordinary top-level declaration with a new keyword. * We're are deprecating mdo for recursive do-notation, in favour of the more expressive rec statement. * We've concluded that the implementation of impredicative polymorphism is unsustainably complicated, so we are re-trenching. It'll be deprecated in 6.12 (but will still work), and will be either removed or replaced with something simpler in 6.14. The full release notes are here: http://haskell.org/ghc/docs/6.12.1/html/users_guide/release-6-12-1.html How to get it ~ The easy way is to go to the web page, which should be self-explanatory: http://www.haskell.org/ghc/ We supply binary builds in the native package format for many platforms, and the source distribution is 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).

Re: ANNOUNCE: GHC version 6.12.1
I've the 6.10.4 version installed on my MacOS X 10.6 OS. Have I to uninstall this version of GHC before installing the Mac .pkg for the 6.12.1? Most installer packages (_except_ for MacOS) allow you to have multiple previous versions of ghc - they are simply left in place (but must now be accessed as e.g. ghc-6.10.4 rather than plan ghc, which now points to the new version). However, there is an unfortunate feature/bug of the MacOS installer packages that they forceably delete any previous versions of ghc that you had on your machine. This is undesirable for many reasons, but as far as I know, it has not yet been fixed.

RE: ANNOUNCE: GHC version 6.12.1
Luca, to use Control.Parallel, you need to download and install two packages, deepseq and parallel, from hackage.haskell.org. Most likely this will work with cabal, or you just download the two tarballs . The reason is, when packaging parallel, this package has been removed from the GHC core libraries. BTW I am unsure whether this is at all clever, since it needs specific GHC support (at least for now - am I right here?) In addition, be informed that Control.Parallel.Strategies has been heavily restructured just last month (splitting it into deepseq and parallel is one of the changes, but not the most fundamental). If you want to try examples from GpH publications, you will certainly have some problems. parallel-1.x versions containing the original definitions are on hackage as well and should work for experiments. Cheers Jost Berthold PS: Loading Control.Parallel into ghci is a handy debugging procedure for the sequential parts of your program without any hassle, but if you do not compile and link your program, it will not use any parallelism (and run slow anyway).

ByteString-backed Handles, and another couple of questions
Hi, Simon - I just added support to Data.Text for your new Unicode-based Handle implementation, and I'd like to write some tests. The natural way to do this would be to create Handles that will write to, and read from, ByteStrings. Does any such code exist at the moment? I don't see it in base or bytestring, though all the necessary abstractions appear to be present. Also, the place I hooked into the new I/O machinery was at the next level up from CharBuffer. Because the implementation of CharBuffer isn't abstract, I had no opportunity to put a text array in there, so there's an extra amount of copying that happens when going from byte buffer to char buffer to Text. It's a bit of a shame, but I don't see a way around it at the moment. Would you be interested in trying to remove that extra copy, or is the current interface set in stone? Many thanks for your great work on this, Bryan. ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
