Re: [Haskell-cafe] Error when building executable with profiling enabled

That means I do not get profiling information for the code that gets spliced in? Or for the code that is producing the splice? What's the work-around for the first case?

Re: [Haskell-cafe] Error when building executable with profiling enabled
I switched to profiling through Cabal as you suggested, but now I have the error: bench\HLogo\Custom\Custom.hs:1:1: cannot find normal object file `dist\build\custom\custom-tmp\Framework\Keyword.o' while linking an interpreted expression So, I removed managing the executables directly from Cabal (--enable-executable-profiling) , and only enabled library profiling. Then I manually compiled each executable twice as: ghc --make Custom.hs ghc --make -prof -osuf p_o Custom.hs Profiling now works. Thank you.

[Haskell-cafe] Error when building executable with profiling enabled
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 ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Error when building executable with profiling enabled
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#id624714. Other than following the documentation I would recommend using Cabal which handles the necessary flags and double-compilation process itself.
