You are using TemplateHaskell (-fth switch) which can be tricky. Please see
this documentation on profiling with TH:
http://www.haskell.org/ghc/docs/7.6.1/html/users_guide/template-haskell.html....
Other than following the documentation I would recommend using Cabal
which handles the necessary flags and double-compilation process itself.

Hello,
i have an executable where i want to run profiling on.
I do:
ghc --make -prof -auto-all -fth Custom.hs
but it does not built and the output is:
bench\HLogo\Custom\Custom.hs:1:1: Dynamic linking required, but this is a non-standard build (eg. prof). You need to build the program twice: once the normal way, and then in the desired way using -osuf to set the object file suffix.
I tried googling on the error with no success. What can I do to compile this file for profiling?
Cheers, Nikos
