Hi
My cabal.exe comes from the hackage website, the binary you put up some time ago. I guess that is probably the issue.
What version is that then?
I'm interested because we've not actually worked out why the problem was occurring.
We still haven't since I'm now not able to replicate the problem...
My best guess is that I had Cabal old installed, which didn't support --builddir. I upgraded to Cabal new which did. Cabal install had cached the Setup.exe program built before the upgrade so that the Setup.exe still used Cabal old. Now, when I try again today, it picks up Cabal new.
Yes that's quite plausible. It forgets what version of Cabal was used to build Setup. So it's not rebuilt if it changes.
I guess there is a potential bug that cabal install should perhaps rebuild setup.exe if the cabal version has changed, but that might be difficult to track and is very much a corner case.
Right. It's not that tricky though. We'd have to record another state file in dist/setup/.
everything. However, I'd like to know (before I push a change) that build-type:Simple will work out the box with the Cabal that got installed with ghc-6.8.3.
It will.
Fantastic. If I break everyones build, I'm blaming you :-)
Heh. I'm confident. :-) Duncan
