I've made a minor change to GHC, and before submitting a PR, I'd like to validate the change. But I don't really know how to interpret the output of the `validate` script. Mine runs for about 40 minutes and then ends in an error: # We are installing wrappers to programs by searching corresponding # wrappers. If wrapper is not found, we are attaching the common wrapper # to it. This implementation is a bit hacky and depends on consistency # of program names. For hadrian build this will work as programs have a # consistent naming procedure. if [ -L wrappers/ghc ]; then echo "ghc is a symlink"; fi ghc is a symlink cp: target 'dir/bin/ghc' is not a directory make: *** [Makefile:197: install_wrappers] Error 1 ________________________________________________________ Executed in 39.60 mins fish external usr time 146.65 mins 0.00 millis 146.65 mins sys time 9.55 mins 1.60 millis 9.55 mins I'm in the process of trying `validate` on a fresh checkout, but at 40 minutes per shot, I feel like I might be on the wrong track. Should I just create a merge request and rely on CI for the validation? Or do something else? Norman
