Comment 2 Sergei Trofimovich (RETIRED) 2013-01-16 17:45:40 UTC

Interesting. You are one of those who has got
base with stat incorrectly linked in base.
It's sympthomes are 'ghci -package base' failing.
We don't have sane workaround yet. Only using 'USE=binary ghc'.

Comment 3 Sergei Trofimovich (RETIRED) 2013-01-16 17:46:28 UTC

Another instance of the same problem: https://github.com/gentoo-haskell/gentoo-haskell/issues/202

Thanks, lol, yeah I started with [source] not [binary]. I have most off the other necessary components added. I'm going to stick with my current installation as I've compiled it around 13 times. (24+hrs cooking) and I don't think it's contaminating my system. I was trying to get dev-haskell/glib on, and vector a dependency for a few others. Thanks again for looking into it and let me know if you'd like my environment file.

I also have a mlton bug that's related if it helps
ref: bug 452558

Still having this issue after upgrade, GHC - 7.6.2 linking :
ghc: /usr/lib64/ghc-7.6.2/base-4.6.0.1/HSBASE-4.6.0.1.o: unknown symbol 'stat'

Created attachment 340076 [details]
logs asked by error return.

Same here.

Comment 9 Sergei Trofimovich (RETIRED) 2013-07-27 20:47:29 UTC

Does the error still occur for any of you
after rebuilding ghc against current gcc/binutils/glibc?

I can confirm that I still get this error with dev-haskell/vector-0.10.0.1. I'm using the following packages:
sci-mathematics/glpk-4.50
sys-devel/binutils-2.23.2
sys-libs/glibc-2.17
sys-devel/gcc-4.6.4
dev-lang/ghc-7.6.3
I'm not sure if using the masked glpk or binutils rules me out, but I can't roll back on either. Let me know if you'd like my current dev-haskell/* merge list. I've compiled almost everything except vector and packages dependent upon.

Oh, both of you and Zhu Sha Zang have gcc-4.6 and -Os in CFLAGS.
Philipp Riegger, do you happen to use -Os?
I'd like to see your emerge --info as well.
Trying to reproduce here.

Reproduced successfully on gcc-4.6.3 / CFLAGS="-Os -march=native".
Will try to investivate what exactly triggers a bug.
Looks like uninlined __hscore_stat being weak symbol at -Os confuses ghci loader.

Yes, I am using -Os as well.

Comment 14 Sergei Trofimovich (RETIRED) 2013-07-29 09:39:08 UTC

Ok then. The current simplest workaround is to use -O2 instead of -Os for ghc:
For example via portage's package.env subsystem:
  /etc/portage/env/O2.conf:
    CFLAGS="${CFLAGS} -O2"
    CXXFLAGS="${CXXFLAGS} -O2"
  /etc/portage/package.env/ghc-bug-452442
    # workaround https://bugs.gentoo.org/452442
    dev-lang/ghc O2.conf
Meanwhile i'll try to grab ghc patches from ticket #3333 and fix it properly.

I've pushed ghc-7.6.3-r1 to gentoo-haskell overlay (not in the main tree yet)
It has 2 major fixes:
    1. weak symbol support for ghci: https://github.com/gentoo-haskell/gentoo-haskell/commit/42eae8a9b61450d658549ecb0417f8585eeb4f8d
    2. gross workaround for missing libc_nonshared.a symbols: https://github.com/gentoo-haskell/gentoo-haskell/commit/ac1f0cf97724d0f719746d919120bcf20d1a1112
It seems to fix -Os ghci issue here and does not break anythong obvious.
If you have a change to test it in overlay please do and i'll move it to main tree.

I've added the haskell layover and have installed dev-lang/ghc-7.6.3-r1 successfully with MAKEOPTS="-j6". I am also able to confirm, on my end, that dev-haskell/vector-0.10.0.1 emerges successfully. So I think it's o.k to push -r1 over to the main tree. I'm going to stay on the overlay unless things get too buggy.
I'm going to try and emerge it with MAKEOPTS="-j10" where I have it set at in /etc/portage/make.conf regarding bug 456386. Doesn't look related but will post an update.

Thanks for the test! Pushed as:
