no output with LANGUAGE TemplateHaskell about ghc-mod HOT 10 CLOSED

I cannot reproduce this with ghc-mod compiled both with GHC 7.0.4 and GHC 7.4.1.

from ghc-mod.

I meant that ghc-mod check displays the error in any cases.

from ghc-mod.

I'm using 7.4 on Ubuntu. Will try on 7.

I'm using Mac.

same issue on Arch using 7.4.1, calling "ghc-mod check" directly
did a bit of source digging and the problem seems to be a SomeException thrown which is caught by "ghandle ignore" (in withGHC) ignoring it
the error thrown is "ghc-mod: Something.hs:1:14-28: You can't use Template Haskell with a profiled compiler" which is a bit mysterious to me as compiling directly with ghc works fine (might actually be a bug in the ghc api?)
anyway it seems you need a profiled ghc to reproduce the bug. will try to recompile ghc without profiling and see whats what

from ghc-mod.

hmm i just checked and my ghc is -not- built with profiling. a simple test compiler with the ghc api worked, so it might be some custom ghc-mod specific flag/option turned on that triggers the error message. either way the error should not be thrown

from ghc-mod.

ok it thinks that the compiler is built with profiling when ghc-mod is built with it. the temporary solution is to rebuild ghc-mod without profiling.

Do you mean that you have a cabal configuration file which contains
executable-profiling: True
?

from ghc-mod.

not anymore:)

Thank you. I can reproduce it now. It appeared that just ignoring exception is a bad idea. I modified ghc-mod so that it displays internal errors.
