ghc 6.2 fails to build using ghc 6.0.1. After some time into the build process it fails with this error message: /var/tmp/portage/ghc-6.2/work/ghc-6.2/libraries/readline/libHSreadline.a: could not read symbols: Archive has no index; run ranlib to add one collect2: ld returned 1 exit status <<ghc: 4301700 bytes, 2 GCs, 130212/130212 avg/max bytes residency (1 samples), 5M in use, 0.00 INIT (0.00 elapsed), 0.02 MUT (0.78 elapsed), 0.00 GC (0.01 elapsed) :ghc>> make[1]: *** [stage2/ghc-6.2] Error 1 make[1]: Leaving directory `/var/tmp/portage/ghc-6.2/work/ghc-6.2/ghc/compiler' make: *** [stage2] Error 2 !!!

Hm, now ghc developed incompatibility within the same major number :(. Andres: I think we do need to resort to that plan you had - to do a local bootstrapping off hte ghc-bin after all. Although it might be possible to do a check for the installed version, but that its a nightmare to track what builds with what and what fails... Anyway, that's up to you to decide ;). Frederik: meanwhile, if you want the update, you can 1. create a binary backup of the installed ghc (use quickpkg, its either part of portage or gentoolkit) 2. emerge ghc-bin and then 3 emerg ghc This should make you rolling..

This needs to be checked in more detail. I myself have succesfully built ghc-6.2 from ghc-6.0.1, if I remember at all correctly, so this should not be a general problem. I would like to run some tests myself, but I am "absent" for the next two weeks, and will only have access to a suitably powerful machine after that. In the meantime, I'd appreciate any additional experiences you could provide. For instance, does building with the ghc-6.2 binary version, as George suggested, really work for you? George: actually, my plan *was* to check for the version installed, and the GHC people usually try to support building a GHC with an older GHC for quite some time backward. On the other hand, I've discovered that since 6.0 bootstrapping from .hc files is supported again, too; there just aren't any prebuilt .hc files to download, so I have to find out how to build them myself. I will investigate that, too, once I am back.
I tried to remotely build ghc-6.2 with ghc-6.0.1 again, and it succeeded. My guess is that this is a problem not caused by ghc-6.0.1, but by gcc-3.3 ... I'll try to find more information. ks
I did an emerge of ghc-bin 6.2 and try to build ghc 6.2. Got the same error...
I'm getting the same error on link, but it seems that the problem is that the archive is not being built correctly. The reason is that the make file is trying to do: /usr/bin/ar q libHSreadline.a -input libHSreadline.a.list And we get: /usr/bin/ar: creating libHSreadline.a /usr/bin/ar: '-input': No such file This seems to be because configure believes ar can accept the -input option, which in truth it can not. This in turn is because of the lines in the configure script: if $ArCmd conftest.a -input /dev/null >/dev/null 2>/dev/null; then ArSupportsInput='-input' else ArSupportsInput='' fi ar, when it sees a file in the argument list that doesn't exist, merely reports the fact on stderr, but does not actually fail. The exit value is 0. I'm going to try forcing ArSupportsInput to '' in the configure script and rebuild, but ghc does take a while!
Update: Replaced the offending lines in the configure script, and now ghc 6.2 builds fine. I'm convinced it was the culprit. The patch for the configure script is trivial, but I'll pop it in as an attachment. There's probably a better way to do it.
Created attachment 25704 [details, diff] patch to configure script to work around ArSupportsInput issue
Thank you very much for the analysis. I would really like to find out why I cannot reproduce this, though. Do you use a strange version of "ar", somehow? On my machine, the test in the configure script fails as intended, and a simple shell command such as if ar q whatever.a -input /dev/null; then echo yes; else echo no; fi shows ar: -input: No such file or directory no You seem to indicate that on your machine it would show "yes". Do I understand you correctly? ks
The version of ar on this machine does indeed behave differently. Weird! Running the same example ... phaenna% if ar q whatever.a -input /dev/null; then echo yes; else echo no; fi ar: creating whatever.a ar: '-input': No such file ar: Warning: '/dev/null' is not an ordinary file yes phaenna% ar --version GNU ar 2.14.90.0.8 20040114 Copyright 2003 Free Software Foundation, Inc.

Ah, okay. I can reproduce that now, after upgrading to binutils-2.14.90.0.8-r1 (I previously had the stable version). I would almost say that this is buggy behaviour from "ar", but as I don't know enough about binutils, and manually forcing ArSupportsInput to be empty seems safe, I have fixed it in CVS. I have not used your patch, but added the variable setting to mk/build.mk, which should override configure's detected setting. This way, it seems to be more likely that it will work with other ghc versions. It still compiles on my machine, now using the new binutils, so I hope it is okay. Thank you very much for your help. I'm closing the bug.
