Hello all,<br><br>When updating my cabal-install to work with ghc-6.12, I got:<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"><span style="font-family: courier new,monospace;">&gt; cabal configure</span><br style="font-family: courier new,monospace;">

</span></blockquote><div> </div>Then all worked fine. Note that I had ghc-6.12.1 on the PATH and this is Windows XP 64bit. I found the first message rather informative, but unfortunately the command given does not work on Windows in general, as far as I know. For starters, the shell doesn&#39;t seem to like single quotes, but moreover, the full path to the ghc binary has to be supplied, as no symbolic links such as &quot;ghc-6.10.4&quot; are available. Perhaps these messages could be updated to be more helpful to Windows users?<br>
<br><br>Cheers,<br>Pedro<br>
