Report when `--with-cabal` path doesn't exist #9778

Open philderbeast opened 6 months ago

philderbeast commented 6 months ago

Could we please check that what is given as --with-cabal exists when that is possible with cabal-tests? Here I made the mistake of building locally with ghc-9.4.8 not having remembered that I'd switched from ghc-9.8.1. It would be much nicer to read something like the following than the dieWithException dump with a line number, output that runs to about 40 lines in my terminal at full screen (with the zoom I like to read at).

the path supplied as '--with-cabal' does not exist

$ ls ./dist-newstyle/build/x86_64-linux/
ghc-9.4.8/

$ cabal run cabal-testsuite:cabal-tests -- --with-cabal=./dist-newstyle/build/x86_64-linux/ghc-9.8.1/cabal-install-3.11.0.0/x/cabal/build/cabal/cabal cabal-testsuite/PackageTests/CopyHie/setup.test.hs

I'm in support. Probably an easy thing to do too.
