Re: GHC build error: cannot satisfy -package ghc-7.1.20110217

Hi Simon, thanks for the reply. Indeed it is reproducible with a maintainer-clean tree and to be sure I even set up a fresh repo. I'm still unclear what the underlying issue is, but I've worked around it by first running `make` until the error, then editing "./ghc/stage1/package-data.mk" to remove the version from the ghc dep, and finally rerunning `make`. The resulting build performs comparably in the test suite to previous builds, so I think it's probably an okay workaround. Will On Tue, Mar 8, 2011 at 6:44 AM, Simon Marlow wrote:

Hi all, Not to pester, but this problem has me stumped. All of the dependencies that ghc reports are broken/recursive are reported (with identical versions) by ghc-pkg/cabal as being part of my bootstrap install.

Rerunning the offending command with "-package ghc" instead of "-package ghc-7.1.20110217" suppresses the error, but `make` nonetheless insists on rerunning the command with the original arguments. Furthermore, I'm unsure if I'm actually working around a bug or if I'm instead just silencing an error that will slyly retaliate from the shadows. It certainly seems like there's a subtlety with cabal that I don't understand. Any help would be much appreciated.

I don't know what might case this I'm afraid.  Is it reproducible from a completely clean tree? (i.e. make maintainer-clean first).

Cheers,        Simon

I'm not sure what happened with the quote formatting in my original message; sorry about that. Anyhow, I'd really appreciate it if someone would chime in about this issue. Is it something silly that I'm not comprehending about the build system or cabal, or is it a legitimate bug/deficiency?

Thanks, Will

Hi all, I'm building GHC HEAD, and I've encountered the following error a couple times:

The last time I saw this, I realized that `make clean` and even `make maintainer-clean` failed to remove the old .hs and .o files in ./libraries. I ran `find ./libraries | grep "\.hi$\|\.o$" | xargs -n 1 rm` which cleaned things up nicely. Then I had to fiddle around with `ghc-pkg` and unfortunately I don't remember exactly what I did, but everything built fine. This time, the error persists and I'm getting nowhere messing with `ghc-pkg` or manual builds of the offending libraries. It's odd that the dependencies are all shown, although ghc-7.1.20110217 is highlighted in blue (not sure what that means):

The other notable thing is that the versions of the installed packages matches the packages I am building with GHC. I initially thought that it would be a good thing, however now I'm thinking that it's leading to some kind of conflict between the build system and the bootstrap system. In the past I've noticed that cabal does not deal well with different versions of GHC, particularly that it doesn't keep track which version of GHC is used to build and register a package (and the .cabal user directory doesn't have separate subdirectories for different cabal versions). This is quite annoying, since it means one can't really have test installs of GHC without fiddling around with prefixes or sandbox construction. Anyway, I wouldn't be surprised if conflicts from that sort of thing could cause the issue I'm having. So I suppose the question now is, what is the actual cause and should it be fixed in GHC's build system or in cabal's source? Thanks, William
