Description Michal Nowak 2010-09-20 09:03:26 UTC

Description of problem:

ghc-6.12.3-5.fc15.src.rpm rebuild with gold (the alternative linker in binutils) fails because configure script won't find curses:

Additional info:

Since gold might be the default linker (per http://fedoraproject.org/wiki/Features/GoldLinkerDefault) this problem might be worth fixing.

Comment 1 Jens Petersen 2010-09-21 01:18:07 UTC

Could you please attach the full buildlog?

I tried on F14 with gold and it seems to find ncurses fine.

Comment 2 Jens Petersen 2010-09-21 02:24:19 UTC

Well as above I can't reproduce the ncurses issue on F14
(perhaps that only happens on F15?).

However later in the build I ran into:

Checking the verbose ghc output the problem occurs here with :

/usr/bin/gcc -nostdlib -nodefaultlibs -Wl,-r -Wl,-x -o libraries/ghc-prim/dist-install/build/GHC/Generics.o libraries/ghc-prim/dist-install/build/GHC/Generics_o_split/ld.script

Editing the linking script generated by ghc-split:

[ghc-6.12.3]$ sed -i.orig -e "s%libraries/ghc-prim/dist-install/build/GHC/Generics_o_split/%%g" libraries/ghc-prim/dist-install/build/GHC/Generics_o_split/ld.script
[ghc-6.12.3]$ /usr/bin/gcc -nostdlib -nodefaultlibs -Wl,-r -Wl,-x -o libraries/ghc-prim/dist-install/build/GHC/Generics.o libraries/ghc-prim/dist-install/build/GHC/Generics_o_split/ld.script
[ghc-6.12.3]$ 

So question that arises is should ld.gold support relative paths in
link scripts or should ghc be changes to just like the local objects?

Comment 3 Jens Petersen 2010-09-21 02:51:14 UTC

The above sed change only works with ld.gold not ld.bfd.
So it seems to be a ld.gold change of behaviour or regression
compared to ld.bfd.  I would be willing to patch ghc for
Fedora if ld.gold and ld.bfd can agree on at least one of
the versions of link scripts working.

Comment 4 Jens Petersen 2010-09-21 03:21:28 UTC

Ah I reproduced the ncurses problem with binutils-2.20.51.0.11-1.fc15.
Interesting that binutils-2.20.51.0.7-5.fc14 is ok.

That is known issue with the libncurses*.so link script "hacks" in Fedora.
I already have a workaround patch for ghc-terminfo (in package review)
which could be applied to ghc's internal copy of terminfo too.

Comment 5 Jens Petersen 2010-09-21 07:20:39 UTC

Note that the ncurses issue is not ghc specific: I tested
less and w3m for example and they also fail to configure
ncurses.  less builds with ncurses, but w3m fails to link.

I guess ld.gold is not compatible with current ld.scripts.

Comment 6 Jens Petersen 2010-09-21 07:31:30 UTC

I filed bug 635965 for the ld.gold ncurses issue.

Perhaps this bug could be closed.

Comment 7 Michal Nowak 2010-09-21 08:17:17 UTC

Yes, we can close this one since it's not ghc specific. Thanks for investigation, Jens.
