haskell - GHC could not execute htfpp -

-

i getting error 

ghc: not execute: htfpp

when try load file {-# options_ghc -f -pgmf htfpp #-} in header. have installed htf (v0.12)

how can solve (on linux , on windows)

thank you!

community-wiki answer posterity:

htfpp not in path. find how alter path, 1 looks in ~/.cabal folder config file , finds cabal installs binaries default. directory needs added path, or installed binary needs moved there directory is in path. ghc can run -pgmf flag.
