Re: [Haskell-cafe] Patches for (abandoned?) pcre-light

There is no problem with the version of GHC installed. Library pcre-light is importing unsafePerformIO from Foreign, module that doesn't export this function since version 4.7.0.0 of the base package. That causes the build to fail for users of base-4.7.0.0. Importing this function from System.IO.Unsafe solves the problem. I have written to the maintainer as well, but did not received any answer yet. Regards, Daniel Díaz. On Sun, Apr 13, 2014 at 3:21 AM, Carter Schonwald < carter.schonwald@gmail.com> wrote:

Hello, I've tried the new ghc-7.8.1 and have had an issue with building pcre-light as one of dependencies for my project. I've made a patch which fixes this, but I can't reach maintainer by e-mail -- what can I do in this situation? Also, the second (unrelated) question would be: how can I find a package which depends on it in my project? I have found no way to dump a dependency tree in cabal.

Thanks in advance, Nikolay.
