[Haskell-cafe] pcre-light install fails with undefined reference to _impure_ptr

[Stephen Tetley]

Hi Patrick

I think the problem is because PCRE uses c++, and doing a quick web
search shows that _impure_ptr link errors are a recurrent problem for
the PCRE binding with GHC. Funnily enough 6.10.3 worked fine - I
posted to the list a month or two ago with instructions how to do it,
but 6.12.1 fails for me in the same was as it fails for you.

I'll try next with MinGW to see if that works...

Best wishes

Stpehen
