Thanks Aycan. The LD_PRELOAD solution did indeed work. I didn't know about that facility before, so I'm pleasantly surprised.

One gotcha though: I had to add the "fake-library" into the runtime as well; with a command that looked like this:

    ar q libHsrts_thr.a ghcFakeLib.o

where the libHsrts_thr.a comes from the binary distro, and the ghcFakeLib.o is the object file I got by defining those pthread_setname_np and pthread_getname_np. (They do nothing but return 0.)

Thanks,

-Levent.

Hi Levent,

For a quick fix, you may want to create a wrapper script which uses LD_PRELOAD to inject `set_threadname_np` to your runtime. An example is given in this blog page:

I really like the idea of nix. Alas, generating native binaries that can run on SuSE without being in the nix environment is a requirement that's hard to let go. (Everyone in my group would have to start using nix, a tall order.)

Thanks for the advice however, it can indeed come handy for one-off trials if needed. In the meantime, I'm still looking for a binary-linux-distro that doesn't require the set_threadname_np functionality, if anyone can point me in that direction.

Thanks,

-Levent.

You could try the Nix route, which, conceptually, would boil down to:

1. Installing the Nix package manager into your $HOME on the SuSE system
2. Use Nix to install GHC

Which expands to:

1. Following the instructions at:

  https://nixos.org/wiki/How_to_install_nix_in_home_%28on_another_distribution%29#PRoot_Installation

2. Invoking:

  nix-env -iA haskellPackages.ghc

This would require only HTTP access, which, I presume, should be
available within the corporate environment.

All the packages from Hackage can be had precompiled from Nixpkgs,
but that's slightly more involved and requires some reading:

  http://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure

Should you meet trouble, you can always seek help either at
nix-dev@lists.science.uu.nl, or on the #nixos/irc.freenode.net IRC
channel -- both have a vibrant nightlife^W Haskell community.
