[Haskell-cafe] Is anybody on 9.6.1 having problems profiling on a Mac?

[George Colpitts]

Thanks for everybody's help, I have closed the issue
<https://gitlab.haskell.org/ghc/ghc/-/issues/23211>. Sorry for bothering
everyone. As I wrote in the bug:

@adamse </adamse>, @mpickering </mpickering>. You are right, there is
something wrong about my environment file default. When I remove it I can
compile with

 ghc -static -prof -fprof-auto hello.hs

The need for -static is not documented as far as I know so I will file a
doc bug. My apologies for not debugging this earlier. I will keep an eye
out to see when an environment file gets created. Thanks again !
