Hi list,
I've got a number of modules in a project set up like this:
project
|-- foo
|-- bar
|-- baz
`-- sandbox
where 'foo', 'bar' and 'baz' are modules which depend on one another, and
'sandbox' is a sandbox. Before building from scratch, I do a $(cabal
sandbox init --sandbox=../sandbox) in each of the module folders.
If I run $(cabal install ./foo ./bar ./baz) from the projects/ directory,
everything is happy. However, if I reconfigure one of the sub-modules with
different flags, it fails with missing dependencies:
# in foo/
$ cabal build
Package has never been configured. Configuring with default flags. If this
fails, please run configure manually.
# module builds correctly
$ cabal configure --enable-tests
Resolving dependencies...
Configuring foo-0.1...
$ cabal build
dist/setup/setup.hs:13:8:
Could not find module ?System.FilePath.Glob?
Perhaps you meant
System.FilePath (from filepath-1.3.0.2)
System.FilePath.Posix (from filepath-1.3.0.2)
Use -v to see a list of the files searched for.
Glob is installed in the sandbox.
I've tried pointing to the sandbox config file manually with both $(cabal
--sandbox-config-file=project/foo/cabal.sandbox.config) and $(cabal
--sandbox-config-file=project/cabal.sandbox.config) with the same result.
Cabal insists that Glob isn't installed until I nuke the foo/dist directory
and start over.
I figure there's some flag I need to pass to `cabal configure` that I'm
missing, but I can't figure out what it is. Anybody have any hints?
Cheers,
Alex

Hmm, nuking ~/.cabal and ~/.ghc seems to have fixed it.
Good old cabal. When in doubt, delete everything.

That says to me you didn't have the sandbox set up right. I'd have set up
the sandbox and then used --add-source for foo, bar, and baz... or,
sometimes, symlink the original sandbox into those dirs, but I suspect
that's asking for trouble :)

That's exactly what I did. From my setup script:
cabal sandbox init --sandbox sandbox
for folder in $SUBMODULES; do
(cd "$folder"; cabal sandbox init --sandbox ../sandbox)
cabal sandbox add-source "$folder"
done
$SUBMODULES contains ./foo, ./bar, and ./baz

Subject: [Haskell-beginners] Vim + Syntastic + ghc-mod: over-verbose
error messages
Message-ID:
<camlejzammqni7iojphv0-p8zgrfgoytpkngpjvhsmc2-c3n...@mail.gmail.com>
Content-Type: text/plain; charset="iso-8859-1"
I'm not sure if this is the right forum to raise this issue, but:
Trying out the Syntastic plugin in Vim, I've found that it displays
confusingly over-verbose error messages that contain unnecessary
information about the module location of identifiers -- e.g.:
Config.hs|13 col 7 error| Couldn't match type `(Config.ConfigElem,
GHC.Base.String)' with `[GHC.Types.Char]'Expected type: [GHC.Base.String]
-> containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.String
Actual type: [(Config.ConfigElem, GHC.Base.String)] ->
containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.StringIn
the expression: Data.Map.Strict.fromList :: [GHC.Base.String] ->
containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem GHC.Base.StringIn an
equation for `Config.foo': Config.foo = Data.Map.Strict.fromList ::
[GHC.Base.String] -> containers-0.5.0.0:Data.Map.Base.Map Config.ConfigElem
GHC.Base.String
Syntastic uses the output from "ghc-mod check" to generate this, and in
turn I think ghc-mod relies on ghc, since options can be passed to ghc from
ghc-mod using the -g option flag. Does anyone know of a way to modify the
behaviour of Syntastic/ghc-mod/ghc to produce output that's more readable?
