Hi Don,
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.
Thanks for all this. I recently went through the unregisterised bootstrap process myself (for amd64), and I've written some detailed instructions in the Building Guide - you might want to take a look and see if you have anything to add. For unregisterised bootstrapping, I don't recommend using hc-build. The resaon is that hc-build goes to some lengths to make a tree which is safe to 'make install' in, and this isn't necessary for bootstrapping - all you need to do is get to the "working compiler" stage, and then use this to build a completely fresh tree. I've applied your patches, with some small tweaks by myself to avoid breaking the unregisterised bootstrap, which is normally done with a compiler without interpreter support, hence the lack of the readline, haskell-src and other libraries. Cheers, Simon

I've been working from that document the last few days. See below.

Ah! Of course. That is what's going on. I continued my 6.0.1 unregisterised bootstrapping efforts following the latest version of building/building.sgml. The steps therein are successful, and I have nothing to add at this point. Unregisterised, the news is a bit frustrating. Of the cross-port machines that went through successfully (3 of 5), none produced a working compiler. They all resulted in: ghc-6.0.1: internal error: stg_ap_v_ret Please report this as a bug to glasgow-haskell-bugs@haskell.org, However, I have been entirely successfully generating registerised and unregisterised hc on x86-{linux,openbsd} and then bootstrapping on the same platform: this is how the i386 GHC 6.0.1 port in the OpenBSD ports tree now bootstraps (from nothing to full Haskell in 31 minutes on my work box :) The furthest I've made it cross-porting, using a variety of paths in, has been the stg_ap_v_ret bug above. I haven't looked into this further, but will do so in weeks to come. I thought it might be useful to report these results, though. Cheers, Don Below is a list of machines I attempted to port from and to, and any bugs fixed along the way. All host machines had a full installation of GHC 6.0.1.

Ok!! I just bootstrapped 6.0.1 on i386-*-freebsd using unregisterised .hc source from i386-*-openbsd. I carefully did exactly what was in building.sgml, (which I had tried to before but I must then have been doing something systematically wrong :( Anyway, this gives me some confidence that all the failed ports were a systematic error on my part, not GHC's :D $ uname -msr FreeBSD 5.0-RELEASE i386 $ ghc/ghc-6.0.1/ghc/compiler/ghc-inplace ghc-6.0.1: no input files Usage: For basic information, try the `--help' option. $ ghc/ghc-6.0.1/ghc/compiler/ghc-inplace hello.hs hello.hs:1: Failed to load interface for `Prelude': Could not find interface file for `Prelude' (use -v to see a list of the files searched for) I'll solve this library thing, try and build a compiler. And then try a sparc. Cheers, Don

I have found that I need to copy the library/ .hi files across, although Simon Marlow seemed to think that should be unnecessary. Also, ghc/driver/package.conf.inplace seems to become the empty list; I haven't bothered to look into this as it's easy enough just to copy ghc/driver/package.conf.inplace.old over the top of it. This isn't following the new docs online so YMMV. Thanks Ian

Exactly! I tarred up the libraries/ .hi files on the host box: $ find libraries -name '*.hi' -print > /tmp/f $ tar czf ghc-6.0.1-hi.tar.gz `cat /tmp/f` copied them across, and untarred over the tree. Also needed the package.conf.in tweak. And I had to turn off "dl" in the extra_libraries list of package.co.inplace (for FreeBSD). Yay! A pretty straightforward cross-os bootstrap, from i386-*-openbsd to i386-*-freebsd: $ cat hello.hs import System.Info main = print System.Info.arch >> print System.Info.os $ ghc/ghc-6.0.1/ghc/compiler/ghc-inplace --numeric-version 6.0.1 $ ghc/ghc-6.0.1/ghc/compiler/ghc-inplace hello.hs $ % ./a.out "i386" "freebsd" I'll try a cross-processor port now.
