Building cabal-install fails with "duplicate symbols" error #6741

Closed hesselink closed 9 years ago

hesselink commented 9 years ago

I'm on Mac OS X 10.9.5, on the nixos-unstable channel with nix installed via the curl command here. I'm trying to install a haskell environment, using the following nix expression in config.nix:

{ pkgs }: {
  allowBroken = true;
  allowUnfree = true;

  packageOverrides = super: let self = super.pkgs; in {

    haskellEnv = self.haskellngPackages.ghcWithPackages (p: with p; [
      cabal2nix
      cabal-install-bundle
      stylish-haskell
      ghc-mod

      # Other packages here
    ]);
  };
}

I issue the following command:

nix-env --install --attr nixos.pkgs.haskellEnv --option extra-binary-caches http://hydra.nixos.org --option extra-binary-caches http://hydra.cryp.to

This fails installing cabal-install-bundle with the error

I found this, but it doesn't have much information: http://www.fatvat.co.uk/2010/10/duplicate-symbol-myinetntoa-when.html

Judging by HsNet.h, it looks like all the symbols in question have an INLINE CPP macro in front of them, and thus aren't really intended to show up as symbols at all (since their implementation is in a header file!)

If I were to guess, that INLINE isn't expanding properly and is causing any files to import HsNet.h to define the function, causing the duplicate symbol error.

The relevant code:

#ifndef INLINE
# if defined(_MSC_VER)
#  define INLINE extern __inline
# elif defined(__GNUC__)
#  define INLINE extern inline
# else
#  define INLINE inline
# endif
#endif

which doesn't seem unreasonable. Perhaps INLINE comes defined (to some nonsense) from somewhere else?

IMHO, that codes uses inline incorrectly. If the keyword is supposed to suppress the generation of a linker symbol, then static (or even static inline) would be the right choice. In C++ code, the inline keyword would have the effect of generating a weak symbol that doesn't cause duplicate definitions, but in C that is not the case, as far as I know. (In fact, I don't believe that C even had inline at all prior to C99.)

@hesselink, just out of curiosity: why do you build cabal-install-bundle instead of the normal cabal-install?

hesselink commented 9 years ago

I was trying out the setup mentioned on this haskell reddit post. I just tried replacing it with cabal-install and that seems to have worked, and it even got me 1.22 instead of 1.18. So my problem is solved, feel free to close this bug if it's no longer relevant.
