primecount for Haskell

This library provides Haskell bindings to Kim Walisch's primecount library.

Build instructions

First follow the directions for installing libprimecount. As stated in the directions, if you are installing through your system's package manager, make sure to get the development version of the primecount package, which might have a name like primecount-devel. The current version of the Haskell bindings supports any version of libprimecount >= 7.0.

Then you can build the Haskell bindings with Stack or Cabal as usual.

Building libprimecount from source

If you build and install the original primecount library from source, instead of through a package manager, then you need to make sure that your Haskell build system knows where to find it. For example, on Linux libprimecount might be installed to /usr/local/lib64.

Then if using Stack, add the following lines to your stack.yaml or your global ~/.stack/config.yaml:

extra-lib-dirs:
- /usr/local/lib64
extra-include-dirs:
- /usr/local/include

If using Cabal, add the following lines to your ~/.cabal/config:

extra-lib-dirs:
  /usr/local/lib64
extra-include-dirs:
  /usr/local/include

or pass --extra-lib-dirs=/usr/local/lib64 --extra-include-dirs=/usr/local/include as an argument to Cabal.
