runhaskell Setup.hs configure Error: Non-empty library, but empty exposed modules list. Cabal may not build this library correctly
The difference is the added GHC-Options, same thing happens if I try to add an Extensions rule. Is this an intended behavior? /Niklas
Some more wierd behavior: I have a configure script that uses some custom --with-X flags. I now want to access this script through Cabal. If I say
./configure --with-sessiondb-driver=PostgreSQL
the @DB_UPPER@ markers in my files get exchanged for "PostgreSQL". If I instead write
runhaskell Setup.hs configure --with-sesisondb-driver=PostgreSQL
the @DB_UPPER@ markers become "yes". How come? /Niklas

Put the ghc-options in the executable stanza, since that's what you're trying to build.

Yep, that's the intended behavior. The sanity checker has noticed that you put the ghc-options field in the first stanza, for the library, but since there aren't any exposed modules, there is no library to build, so it complains. The solution is to move the GHC-Options field to the executable stanza. peace, isaac
