With both ghc6.2 and 6.2.20040915 on Linux, ghc --make cannot compile
the attached files and produces a confusing error message.
# ghc --make View.hs
Chasing modules from: View.hs
Compiling ViewType ( ./ViewType.hs, ./ViewType.o )
Compiling VersionGraphClient ( ./VersionGraphClient.hs, ./VersionGraphClient.o
)Compiling View ( View.hs, View.o )
View.hs:14:
Couldn't match `VersionGraphClient' against `VersionGraphClient'
Expected type: VersionGraphClient
Inferred type: VersionGraphClient
In the `graphClient1' field of a record
In the record construction: View {graphClient1 = graphClient}
However ghc without make has no problems.
# ghc -c ViewType.hs
# ghc -c VersionGraphClient.hs
# ghc -c View.hs
best wishes to all Simons!
