To install GHC, download a binary build from http://haskell.org/ghc/. Although source code for GHC is available, it will take a very long time to build by yourself. Pugs needs Parrot 0.2.0 or above to support Perl 6 Rules. To install Parrot, follow the instructions at http://www.parrotcode.org/. http://www.jwcs.net/~jonathan/perl6/ has binary builds for Win32. If you'd like to build by hand, http://wiki.kn.vutbr.cz/mj/?Perl%206%20and%20Parrot has instructions (and binaries, too). For dynamic loading/inlining of Haskell modules, you should install the hs-plugin library, available here: ftp://ftp.cse.unsw.edu.au/pub/users/dons/hs-plugins/snapshots/ To install Pugs on your system, simply type this in the command line: cpansign -v # optional; see SIGNATURE for details perl Makefile.PL make # or 'nmake' on Win32 make test make install Optionally you may use the GHC environment variable to set the ghc executable before you run "perl Makefile.PL", for example: export GHC=${HOME}/bin/ghc (bash) setenv GHC ${HOME}/bin/ghc (csh) CAVEATS FOR GCC 4.0 USERS ------------------------- Mac OS X 10.4 "Tiger" users may see this error message when compiling Pugs: ___DISCARD__ collect2: ld returned 1 exit status Until GHC 6.4.1 is released, you need to need to issue this command first: sudo gcc_select 3.3 Then recompiling Pugs using a clean tree. Other users of GCC 4.0 systems may also need to switch to use GCC 3.3 to compile Pugs at this moment. CAVEATS FOR x86_64 MACHINES --------------------------- Until GHC 6.4.1 is released, users with x86_64 (64 bit Athlon) CPU's should consider using a development snapshot of GHC. GHC 6.4 had bugs on x86_64 which break garbage collection and rules (regexps). These bugs were fixed in GHC CVS by around 11-May. There are hints on using snapshots at the end of this section. Here are the known problems: (1) GHC 6.4 has a garbage collector bug on x86_64 (64 bit Athlon) machines; users may see crashes complaining about "strange objects". Until GHC 6.4.1 is released, a partial workaround is to avoid GC by requesting a large heap, using either command line arguments: ./pugs +RTS -A200M -RTS or an environment variable: GHCRTS='-A200M' These request a 200 MB heap, which is sufficient to run most programs. Running all tests unfortunately requires a lot more memory (perhaps 1000M). A possible alternative, which someone could explore and report on, would be to try using a 32-bit GHC instead. (2) Rules (regexps) may not work with GHC 6.4 on x86_64. Users may see "internal error: adjustor creation not supported on this platform". There is no known workaround. This bug has been fixed in current development snapshots. Hints on using a development snapshot of GHC: Note that this will take a long time, and it may not work. First, check if a sufficiently recent "Stable" source snapshot is available (as of 15-May, there isn't one yet). If not, you might try a "HEAD" snapshot (it is not clear anyone has actually tried this). Otherwise, use might use cvs to grab your own snapshot: CVSROOT=:pserver:anoncvs@glass.cse.ogi.edu:/cvs; export CVSROOT cvs login # passord cvs cvs checkout fpconfig cd fptools cvs checkout ghc hslibs libraries happy alex autoreconf ./configure make make install There are no guarantees with a CVS snapshot. It may not even compile. MAILING LISTS ------------- The mailing list for Pugs is perl6-compiler. Subscribe by sending mail to .
