Help with unregisterised build

[Peter Tanski]

Hello Jeremy, I don't know if anyone has gotten back to you on this yet.  I have not myself done an unregisterised build of GHC before, but I thought you should at least hear something.  The people who know about this all seem to be at the ICFP programme that has been going on since Thursday; they should be back next week.  In the meantime, some work has been done recently on the way GHC puts out assembler--not quite the same problem as a multiply-defined-symbol error--but you might consider grabbing darcs and trying to build from the HEAD branch.  See <http://hackage.haskell.org/trac/ghc/wiki/Building/GettingTheSources>.   -Pete Jeremy Wazny wrote: I've attempted to build an installation of GHC which uses unregisterised libraries, but have not had much success. I am new to GHC's build system and would be grateful for some advice. I'm trying to build the 6.4.2 source distribution on an x86 linux machine, using GHC 6.4.2 (the "Generic Linux with glibc2.3" version on the download page.) The target is the same machine.  I've created a mk/build.mk file containing just the line: GhcUnregisterised = YES which, according to the comment in mk/config.mk, ought to build the unregisterised libraries that I'm after (and use them by default.) I run configure as follows: ./configure --prefix="$HOME"/ghc_u and then simply "make". After some time, the build fails with the following: ../../ghc/compiler/ghc-inplace -H16m -O -fglasgow-exts -cpp -Iinclude -"#include" HsBase.h -funbox-strict-fields -ignore-package base -O  Rghc-timing -fgenerics  -fgenerics -split-objs    -c GHC/Base.lhs -o GHC/Base.o  -ohi GHC/Base.hi /tmp/ghc4237.s: Assembler messages: /tmp/ghc4237.s:17: Error: symbol `__stg_split_marker' is already defined /tmp/ghc4237.s:29: Error: symbol `__stg_split_marker' is already defined /tmp/ghc4237.s:41: Error: symbol `__stg_split_marker' is already defined /tmp/ghc4237.s:53: Error: symbol `__stg_split_marker' is already defined ....

I'm not sure what to do at this point.  Am I missing something in the build.mk? Is there likely to be anything else that needs to be tweaked? Has anybody had any success with this sort of thing before?
