Dear list,

I build haskell-platform 2011.04 by gentoo ~amd64 haskell overlay. But I can't run ghci even I rebuilt ghc or run haskell-updater, error message:

ghci GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... ghc: /usr/lib64/ghc-7.4.1/base-4.5.0.0/HSbase-4.5.0.0.o: unknown symbol `stat' ghc: unable to load package `base'

Do you have some ideas how to avoid this error? Many thanks.

Best Regards Baojun

Anyway; you could try to do "cabal install base" or so.

Furthermore, you could try to join the #gentoo-haskell channel on freenode-IRC which should be able to help you if it's a gentoo-specific problem.

Cheers.

Many thanks Morel. Yes, I also tried reinstall base, but also get error: $ cabal install --reinstall base Resolving dependencies... cabal: Could not resolve dependencies: next goal: base (user goal) rejecting: base-4.5.0.0, 4.4.1.0, 4.4.0.0, 4.3.1.0, 4.3.0.0, 4.2.0.2, 4.2.0.1, 4.2.0.0, 4.1.0.0, 4.0.0.0 (only already installed instances can be used) rejecting: base-3.0.3.2 (conflict: base => base>=4.0 && <4.3) rejecting: base-3.0.3.1 (conflict: base => base>=4.0 && <4.2) It is very strange there is no error when run ``haskell-updater'' (38 packages), but if I run ``cabal install type-level'', it will also fail due to unable to load base.o I'll try irc later. Best Regards Baojun

cabal-install cannot install base; it is and must be part of the compiler. The error does not say that base is missing, it says that base is present but broken (stat() is a libc function, not part of base).

The recommendation to check with #gentoo-haskell, however, is a good idea; it's clearly a problem with the Gentoo package.

Many thanks for your prompt reply Brandon. I think you are right: In /usr/include/sys/stat.h: #if defined __GNUC__ && __GNUC__ >= 2 && defined __USE_EXTERN_INLINES /* Inlined versions of the real stat and mknod functions. */ __extern_inline int __NTH (stat (__const char *__path, struct stat *__statbuf)) { return __xstat (_STAT_VER, __path, __statbuf); } Please find more details in http://pastebin.com/DHium87b Best Regards Baojun
