In ghc 7.8.3 on the Mac, for some packages, cabal reinstalls the package instead of telling me I've already installed it. #2108

In ghc 7.8.3 on the Mac, for some packages cabal reinstalls the package instead of telling me I've already installed it. ghc-pkg check shows I have no issues, e.g.:

bash-3.2$ cabal install cabal-install Resolving dependencies... Configuring cabal-install-1.20.0.3... Building cabal-install-1.20.0.3...

Other packages that have this problem include alex, and an example of a package that doesn't have this problem is vector. Should I file a bug?

It's a known issue, Cabal doesn't track installed executables. See e.g. #227.

mietek commented 10 years ago

#227 is the number of the original Trac issue, which is no longer available. #220 is the GitHub issue number.

It's unfortunate that issues were imported without respecting or remapping the issue numbers, as many cross-references are broken due to this.

I don't understand why my bug is either of the known issues I have been referred to

As for the first, my problem is not with all executables, it is with some, and the other part of the problem which I didn't stress in my original report, is that the problematic packages never show up in ghc-pkg list.

a good package, e.g. hlint does not reinstall after a second cabal install and it does show up in ghc-pkg list. A bad package e.g. alex reinstalls after a second install and never shows up in ghc-pkg

Here's the output to show that:

cabal install -j3 hlint Resolving dependencies... Downloading haskell-src-exts-1.16.0... Configuring haskell-src-exts-1.16.0... Building haskell-src-exts-1.16.0...

Packages only show up in ghc-pkg list if they install a library. Executable-only "packages" aren't really packages from GHC's point of view. hlint installs a library and an executable, but alex installs only an executable. So, hlint is tracked by alex is not; that is why you are only having trouble with some executables.
