Stop. Sigh, I'll re-roll the source dist. Thanks for pointing it out. Simon

ANNOUNCE: GHC 5.03.20020410 snapshot released
by Simon Marlow 11 Apr '02

11 Apr '02

Another snapshot along the 5.03 line, we expect this to be the last snapshot before 5.04. As before, there are NO GUARANTEES as to the stability of this release, but it has passed our three-stage bootstrap and all but one(!) of the 754 regressions tests passed. Documentation is also still lagging behind the new features. Get it from the usual place: http://www.haskell.org/ghc/ Changes since the previous snapshot (5.03.20020204): * GHC switched over to the new hierarchical library structure for its base libraries. The old hslibs and the standard Haskell 98 libraries are still there, so you shouldn't notice any difference for existing code. We're currently working on documenting the new library structure for the next release. * The syntax for implicit parameters has changed: implicit bindings are now introduced with the let keyword instead of with. The bindings in a let must be either all implicit bindings or all explicit, not a mixture of the two. The old with syntax will be supported for a couple of versions or so, but will elicit a warning message from the compiler if you use it. * Foreign export dynamic is allegedly working in GHCi. * Generics are working again. * Explicit kind annotations can now be given on type variables. See the documentation (type system extensions, explicitly-kinded quantification) for more details. * Interface files are now in a binary format for speed of reading/writing. Use ghc --show-iface to show the textual representation of an interface. The synatx of .hi-boot files has changed, and is now much more readable. Cheers, Simon

getting types out
by Hal Daume III 10 Apr '02

I know -ddump-types will get me the types of top level functions, but is there a way to get ghc (or really any compiler) to dump the types of everything (or at least more than that, maybe just locally bound definitions)? - Hal -- Hal Daume III "Computer science is no more about computers | hdaume(a)isi.edu than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume

register error
by Andre W B Furtado 10 Apr '02

10 Apr '02

While trying to install GHC-5.02.3 (win32 release) in my computer (Windows 98), I got the following error message: Error 1406: Could not write value _MainFeature to key HKEY_LOCAL_MACHINES\Software\Microsoft\Windows\CurrentVersion\Installer\Feat ures\8C655693FA0801D4E87FA1CA60C4AAE1 Verify that you have sufficient access to that key, or contact your support personel. I then finished the installation, and would like to ask 2 things: 1. What problems am I supposed to expect with this error? 2. Why this happened? I though I had sufficient access to all needed register keys... :) Thanks, -- Andre

We'd like to do something like this, but it's not high up the priority list. For the time being, you can use normal Makefiles with 'ghc -M' to create dependencies, and then use 'make -j' to get parallelism. Cheers, Simon

concurrent --make
by Serge D. Mechveliani 10 Apr '02

Dear GHC (5.02.2), By occasion, can you --make things parallelwise, concurrently ? For we have 6 processors here, and ghc -O --make <HeadModule> takes more than 60 minutes on one procesor to `make' my application (to find import dep-s, compile many .hs modules, create libraries). Also `making' GHC from source takes more that 4 hours on one processor. ----------------- Serge Mechveliani mechvel(a)botik.ru

RE: GHC 4.08.2 binaries for OpenBSD i386 available
by Simon Marlow 10 Apr '02

Hi Donald, > I've finished a port of GHC 4.08.2 to OpenBSD i386. > The binary package (12M) can be ftp'd from: > > ftp://ftp.cse.unsw.edu.au/pub/users/dons/ghc/ghc-4.08.2.tgz That's great news. Have you tried using that to build a newer release of GHC? I'd like to get any patches that you have incorporated into the main tree so we can support OpenBSD in the future. Cheers, Simon

You can also have a private package configuration file, which you can use by saying '-package-conf <file>' on the GHC command line, and '-f <file>' to ghc-pkg to add/remove packages from it. Packages in user-defined package configuration file override those in the system configuration file. Cheers, Simon

adding package
by Serge D. Mechveliani 10 Apr '02

10 Apr '02

Dear ghc (5.02.2), For the fist time you are installed on our Linux machine to the system area. And I discover two points. 1. You are in Debian-Linux distribution! Hence, it is easy to install GHC as regular, without fighting with library versions etc., by asking administrator to intall a Debian package. So, we'll wait for 5.02.3,... to appear in Debian-Linux distribution. 2. As you have come to the system area, my application cannot install. Makefile creates the package docon and commands ghc-pkg -a ... "you don't have permission to modify the package configuration file make: *** [init] Error 1 " Something like a package configuration is visible at /usr/lib/ghc-5.02.2/package.conf, Does my `ghc-pkg -a ...' try to modify this file? I am not a system user, have not right to modify it. Please, what is the regular way out? Maybe, this package.conf should be installed indifferent place (in what way?). How does the user add a package? Thank you in advance for the explanation. ----------------- Serge Mechveliani mechvel(a)botik.ru
