"How to build" section missing

[dschoepe]

The beginning of README.md mentions a "How to build" section. However, the section no longer exists in the README and using inline-c as is causes linker errors. It seems the section was removed in commit https://github.com/fpco/inline-c/commit/ffb1f9373cc4709d45fd66b6a6b3ce0ef64983c7.

The instructions there still work and fix the linking errors that occur for me otherwise. Is specifying c-sources etc. in the cabal file still required or should one handle this another way now?

Here's a counter example that fails for me when following the current documentation:

import qualified Language.C.Inline as C
import Foreign.C.Types

test :: IO CInt
test = [C.exp| int{ 5 } |]

I get the following error in a default stack project when running stack build without specifying c-sources:

the current readme refers to the current version, which does not require a separate linking step. please refer to the readme of the version you're using.

you're right that there is a broken reference though, i'll fix.
