Thanks for the pointer!
I was able to compile and run the sample program Resize.hs (“ghc –make
Resize.hs”), but when I load that module into GHCi and run main, I get a
run-time error:
*Main> main

A little googling found an issue: Crash when running a sample program in
ghci on OSX <https://github.com/bsl/GLFW-b/issues/53>. One comment
recommends the following in ghci:
:set -fno-ghci-sandbox
When I use this command in a fresh ghci process (not after a crash), the
sample works. However, when I run “main” a second time, the window doesn’t
appear. Instead, I get some sort of undead process (called “ghc”) that I
have to kill manually.
I installed wxWidgets via “brew update && brew install wxWidgets” and
wxHaskell via “cabal update && cabal install wx”. I’m running Mac OS 10.9.5.
Has anyone gotten this latest wxHaskell to play well with ghci on Mac OS?
