ghc-7.6.3 does produce a better error now:

We are using the binary tarball for 7.6.3 on Ubuntu 12.04 LTS extensively. The only trouble we ever encountered was that when installing GHC on a VM with a very minimal install of 12.04 64-bit, we had to temporarily install the 32-bit versions of a few basic Ubuntu system packages to get the GHC installer to work. After that we returned the machine to single-arch 64-bit and everything is fine. What problems have you encountered? -Yitz _______________________________________________ Haskell-Cafe mailing list [hidden email] http://www.haskell.org/mailman/listinfo/haskell-cafe |

Hi, I tried the 64bit binary packages from
haskell.org/ghc but I got a complaint that libgmp.so.3 is not found on my system (and locate did not reveal it). I have several of these libgmp.so, but apparently not the right one locate libgmp.so /usr/lib/i386-linux-gnu/openssl-1.0.0/engines/libgmp.so /usr/lib/i386-linux-gnu/ssl/engines/libgmp.so /usr/lib/x86_64-linux-gnu/libgmp.so /usr/lib/x86_64-linux-gnu/libgmp.so.10 /usr/lib/x86_64-linux-gnu/libgmp.so.10.0.2 /usr/lib/x86_64-linux-gnu/openssl-1.0.0/engines/libgmp.so Here I already gave up. Since compiling from source worked, I did not investigate further...

On Mon, Oct 21, 2013 at 12:42 PM, Andreas Abel <[hidden email]> wrote: Hi, I tried the 64bit binary packages from It's a side effect of the distro that these packages are built on. They have a libgmp.so.3 that configure finds/uses, but I think most distros no longer install that. Often times they do have a suitable libgmp and a symlink can fix the issue.
What I do when I run into this is something roughly like this: 1. Run ldd on the executable that is complaining (alternatively, you can use readelf -d), to find out what shared object is not being loaded correctly and get a hint of the expected path. If you can't figure out the path, then assume it will be the same path used by other .so files.
2. Find a close match, such as the ones you found with locate. 3. (Optional) install the necessary package because no close match is there. 4. Create a symlink in the right place.
Building from source is usually easier :) Jason _______________________________________________ Haskell-Cafe mailing list [hidden email] http://www.haskell.org/mailman/listinfo/haskell-cafe |

indeed, isn't the usual fix to make sure you've got the "dev" version of the package name installed? On Mon, Oct 21, 2013 at 3:58 PM, Jason Dagit <[hidden email]> wrote:

Not here; libgmp.so.10 isn't going to match libgmp.so.3 regardless. And it's not determined while building a Haskell program, unless that program is the ghc you are going to use to build other Haskell programs.

That works in some cases, but it's not the solution here. In this case the problem is that the elf section lists a filename that doesn't exist (libgmp.so.3) and the symlink redirects it to the real filename (libgmp.so.10).

Andreas, please feel free to use my PPA for GHC 7.6.3[1] and cabal-install[2]. This assumes that you install GHC and cabal-install over with APT and everything else with cabal-install. Alternatively you can also use a binary that I built on Ubuntu 13.04 [3]. Cheers.

The Debian libgmp package is named libgmp3 on Ubuntu, though I don't know why.

If this is a single-user desktop machine and you would like to have a modern GHC with a lot of packages built in, you can also try my pet project called 'Ceh', see the docs here: - https://github.com/errge/ceh or the slides here: - http://www.gergely.risko.hu/fpafternoon-zurich-20130829/ceh.html I use this solely for all my haskell work in the last half year, even for recompiling GHC itself, so it's pretty stable and usable by now.

Simon, I'd assume many Linux users of GHC might find this helpful. How about putting this up on the GHC release pages? I mean it is the official GHC pages where I go looking first for a working install, and I am expecting to find it there. If you have a solution for Ubuntu (that the current pages do not provide), it would make sense to put it up there. Cheers, Andreas -- Andreas Abel <>< Du bist der geliebte Mensch.
