Hey all, Here is a (long) summary of how I have bootstraped GHC on various os/arch combinations using 6.0.1 .hc source, including getting an unregisterised build, over the weekend. 1. Generating registerised .hc files ------------------------------------- ...on a machine with GHC 6.0.1 installed. This process has worked on an x86 OpenBSD box, and an x86 Linux box. I used the following build.mk, extracted from the nightly build scripts: --------------------------------------------------------------- GhcStage1HcOpts = -H48m -fvia-C GhcStage2HcOpts = -H48m -fvia-C GhcStage3HcOpts = -H48m -fvia-C -keep-hc-file GhcLibHcOpts = -H48m -fvia-C -keep-hc-file GhcLibWays = SplitObjs=NO # add this after the normal build, and after 'gmake clean' in # utils, in order to get the proper symbols in utils #SRC_HC_OPTS+=-keep-hc-file -fvia-C -H48m BIN_DIST = 1 --------------------------------------------------------------- The process was as follows (presuming you have untarred a nice, shiny ghc-6.0.1 src): $ ./configure $ make bootstrap3 This was all good, but the problem was: no .hc files were made in ghc/utils. Setting SRC_HC_OPTS the whole time was no good, as we ended up with wrong symbols in ghc/utils/*.hc. The solution is to then: $ ./configure --with-hc=`pwd`/ghc/compiler/ghc-inplace # then uncomment out the SRC_HC_OPTS line of mk/build.mk $ ( cd ghc/utils ; make clean ; make ) $ make hc-file-bundle Project=Ghc You should now find a proper .hc file bundle in the fptools directory, ready to install over the full Haskell source. Also, I had a weird problem with parser-generated files missing in the .hc build. This was due to the hc-file-bundle from the shadow tree containing *links* to the now-missing parser generated .hs files, not the files themselves. The solution is to do the above .hc generating build inside a real tree, not a shadow (lndir'd) tree. 2. Bootstrapping with registerised .hc files -------------------------------------------- I had to modify 3 files: distrib/hc-build: to correctly touch stage1 files for "make install" mk/bootstrap.mk: was out of date for 6.0.1 libraries libraries/readline/Makefile: didn't like stub files on booting Then: # untar the .hc source of a clean Haskell source tree $ distrib/hc-build --prefix=`pwd` $ make install stage=1 With these steps, and the following 3 patches, I was able to boostrap from 6.0.1 .hc files successfully on both Linux and OpenBSD x86 boxes. 3. Unregisterised building -------------------------- Now by following the above instructions, and applying the appended patches, along with setting "GhcUnregisterised = YES" in the first build.mk, and then again in the bootstrapping distrib/hc-build, *and* running distrib/hc-build with --enable-hc-boot-unregisterised I was able to build an unregisterised compiler and libraries successfully on an x86 box (didn't try on Linux this time). I am about to see if I can take these unreg files and boot a sparc straight to 6.0.1. The main problem in all of this was generating correct .hc files in the first place :) Cheers, Don The patches (to get .hc building working) for SimonM to look at: ------------------------------------------------------------------------ --- distrib/hc-build.orig 2003-07-25 20:23:30.000000000 +1000 +++ distrib/hc-build 2003-08-25 13:47:44.000000000 +1000 @@ -72,11 +72,6 @@ primop-usage.hs-incl \ primop-primop-info.hs-incl" -# The reconfigure step updates a few files, which can lead to -# unnecessary recompilations.
