Consider
http://code.haskell.org/mohws/mohws.cabal
When I include Paths_mohws as Other-Modules, 'cabal haddock' aborts with:
thiel...@euler:~/programming/haskell/mohws> cabal haddock
Preprocessing library mohws-0.2.0.1...
Preprocessing executables for mohws-0.2.0.1...
Running Haddock for mohws-0.2.0.1...
Warning: The documentation for the following packages are not installed. No
links will be generated to these packages: rts-1.0
Preprocessing library mohws-0.2.0.1...
Preprocessing executables for mohws-0.2.0.1...
cabal: can't find source for module Paths_mohws
When I remove Paths_mohws from Other-Modules then the library and
executables in the package can be built successfully. But when I compile
an executable outside the package, then I get a linker error:
parallelweb> cabal install

cabal: Error: some packages failed to install:

exit: ExitFailure 1
I use:
$ cabal --version
cabal-install version 0.6.0
using version 1.6.0.1 of the Cabal library
Which way is the intended one? Include Paths_mohws in package description
or not? In general, shall automatically generated files appear in Cabal
file? I think they should not, since they are not part of the distribution
tarball. So can I consider the linker error being a bug?
