Because some libraries' darcs have been updated to fit 6.10. And I do not want to check every library's stable version before I darcs it. So I decide to install ghc-6.10. I have tried a few times, no special action needed, just build 6.10, and as it requires, install the rest. Then, it cannot be made. I will try the binary distribution. Well binary of 6.8 cannot run in my box. Don Stewart wrote:

Hi, I want to install ghc 6.10. Well....

I installed ghc 6.6.1 (binary distribution), and cabal, happy, alex (all from darcs, the latest version). Then darcsed 6.10's source. And made. I got: "templates/GenericTemplate.hs:47:21: parse error on input `#'", when "make -C genprimopcode"

Any idea what should I do? Thanks.

Install a binary release of ghc 6.10. Also note that a) ghc 6.10 isn't released yet , and b) you should know what you're doing,

Cheers! Don

P.S.

More information is required to answer exactly your questions. Ask yourself this question: what information would /I/ need to reproduce what I just did from scratch?

The answer to that is how much context to include in your question.
