How can I install profiling libraries in Haskell when using cabal, in Ubuntu 14.04.5? -

i have haskell project obtain stack trace when exception thrown. using ghc 8.0.2 , module graphics.ui.glut, version of glut 2.7.0.11.

i have installed module using cabal.

this page official website suggests compile using -prof flag. however, following error

 failed load interface ‘graphics.ui.glut’  perhaps haven't installed profiling libraries package ‘glut-2.7.0.11’?  use -v see list of files searched for. 

i using ubuntu 14.04.5 lts. using this link, decided run

sudo apt-get install libghc-glut-prof 

however, did not solve problem. how can solve this?

thank you.

running

sudo apt-get install libghc-glut-prof 

is right thing if indeed use debian package graphics.ui.glut.

if have installed glut package cabal yourself, e.g. with

cabal install glut 

or other package pulls in glut, can run

cabal install --enable-library-profiling --force-reinstall glut 

(or whatever other package installed pulled in glut) rebuild profiling enabled.

none of specific glut.
