Hi all, Turns out this was already a known issue in GHC: https://ghc.haskell.org/trac/ghc/ticket/9762 and a fix is now on the way for 7.10.1. In the meantime, adding -fomit-interface-pragmas works for me. Thanks, David On 19 December 2014 at 20:28, David Turner wrote:

Ok, I can reproduce this with a bare Yesod scaffold (using the latest cabal-install) - see below.

If I run cabal build a couple more times, it completes successfully, which is mighty strange!

[linuxadmin@vm01 20:19:43 ~ ] $ yesod init Welcome to the Yesod scaffolder. I'm going to be creating a skeleton Yesod project for you.

What do you want to call your project? We'll use this for the cabal name.

Project name: linker-test Yesod uses Persistent for its (you guessed it) persistence layer. This tool will build in either SQLite or PostgreSQL or MongoDB support for you. We recommend starting with SQLite: it has no dependencies.

s = sqlite p = postgresql pf = postgresql + Fay (experimental) mongo = mongodb mysql = MySQL simple = no database, no auth url = Let me specify URL containing a site (advanced)

So, what'll it be? simple That's it! I'm creating your files now...

I thought I had disabled profiling there, although it was enabled when I was using cabal which wrote the original command line so that might explain it.

I will try a more recent cabal-install this evening.

Thanks for the speedy response!

[Time passes - second response:]

I have tried cabal-install build from the latest revision (4aabb4f4b1) with the same result. From a clean checkout of my source:

$ ~/cabal/cabal-install/.cabal-sandbox/bin/cabal configure --disable-tests --enable-coverage --disable-profiling $ ~/cabal/cabal-install/.cabal-sandbox/bin/cabal build -v

Similar outcome.

i think the fix for this, or a related problem is merged into cabal/cabal-install head, and will be in 1.22

does your problem go away if you dont enable profiled builds? (is so, its likely the same problem)

Hi,

I'm having trouble making a HPC build of a Yesod application. It fails with:

/usr/bin/ld: dist/build/StreamReading/Config.dyn_o: relocation R_X86_64_PC32 against undefined symbol `_hpc_tickboxes_tracszmenterprisezm0zi0zi0_Settings_hpc' can not be used when making a shared object; recompile with -fPIC

I've narrowed it down to a call to ghc and posted the output in all its gory detail at http://lpaste.net/116872 if that's any help.

Of note is that dist/build/Settings.dyn_o is unexpectedly missing from the list of parameters to the last call to gcc, and the missing symbol is defined in the same. There are, in fact, quite a number of missing .dyn_o files in that list.

Slightly weirdly, when I run the same command line again, it seems to work. At least, there are no errors reported and the exit code is 0.

Any ideas?

Cheers,
