Hello again,
Is this change in behaviour between ghc-6.4 and ghc-6.4.1 desired:
~/trans $ ls foo foo.c ~/trans $ ghc-6.4 -odir foo -c foo/foo.c ~/trans $ ls foo foo.c foo.o ~/trans $ rm foo/foo.o ~/trans $ ls foo foo.c ~/trans $ ghc-6.4.1.20050804 -odir foo -c foo/foo.c ~/trans $ ls foo foo foo.c ~/trans $ ls foo/foo foo.o
It seems to break cabal-1.1.1, in the case that I have something like
c-sources: foo/foo.c
in my .cabal file ...
Yes, this change was made for consistency (someone else reported the breakage). I've also patched Cabal, so perhaps you're using a version from before the fix?
I must be doing something wrong, then. With the dummy package at http://www.iai.uni-bonn.de/~loeh/cabalghc.tar.gz, the ghc 6.4.1 snapshot from 20050809 and a build of Cabal from the darcs repository I get: ~/trans/cabalghc $ ghc-pkg list Cabal /usr/lib/ghc-6.4.1.20050809/package.conf: (Cabal-1.0), Cabal-1.1.2 ~/trans/cabalghc $ runhaskell Setup configure Setup: Warning: No license-file field.
