I cannot get Criterion to work. I followed the tutorial here, installing Criterion by doing the following.
cabal update
cabal install -j --disable-tests criterion
when I try ghc -O Fibber.hs or ghc -O --make Fibber I receive the error
[1 of 1] Compiling Main ( Fibber.hs, Fibber.o )
Fibber.hs:1:1: error:
Could not find module ‘Criterion.Main’
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

1 | import Criterion.Main
|
I expect tests and diagnostics to be run and outputted to the console and an HTML file.
trying with stack results in the same error. I have solved this problem before with my own modules by including them in my .cabal file like so
library
Exposed-Modules:
Geometry.Sphere
Geometry.Cuboid
Geometry.Cube
But doing this same in this case does not resolve the issue. I have also tried this SO solution, but to no avail. I receive basically the same error:
/Users/me/Documents/projects/haskell/performance/criterion-1.5.13.0/Criterion/Fibber.hs:3:1: error:
Could not find module ‘CriterionMain’

description:
This library provides a powerful but simple way to measure software
performance. It provides both a framework for executing and
analysing benchmarks and a set of driver functions that makes it
easy to build and run benchmarks, and to analyse their results.
.
The fastest way to get started is to read the
<http://www.serpentine.com/criterion/tutorial.html online tutorial>,
followed by the documentation and examples in the "Criterion.Main"
module.
.
For examples of the kinds of reports that criterion generates, see
<http://www.serpentine.com/criterion the home page>.

One option is to use a dependency-solved REPL.
% cabal repl --build-depends criterion
> :l Fibber.hs
Another is to create a cabal package.
% mkdir Fibber
% mv Fibber.hs Fibber
% cd Fibber
% cabal init
<follow prompts, and say you're building an executable with filename Fibber.hs>
% vi Fibber.cabal
<add criterion to the build-depends: stanza>
% cabal run Fibber # or whatever executable name you gave it in the cabal init step
One advantage of the latter is that as you discover additional dependencies, you can make a record of all of them in a file, instead of having to remember to pass all of them every time when you start cabal repl. Another is that your code will be compiled, rather than interpreted; rather important for performance testing, which is presumably what you're doing if you need criterion!
