Public bug reported:
Binary package hint: libghc6-haskelldb-dev
I've installed the GHC6, HSQL and HaskellDB Ubuntu-packages. I wrote a
little test program (DBTest.hs) which is meant to simply dump the list
of tables in a test database that I have. But, whether I try to run this
program interactively or compile it, I get linker errors. My guess is
that something about the installation of the HaskellDB Haskell-package
means it isn't aware that it needs to link against the database-specific
HSQL Haskell-packages, since the symbols that it is unable to find are
certainly present in the HSQL libraries. It could be that the HaskellDB
Ubuntu-package hasn't been updated since HSQL was split into several
Haskell-packages. The symptoms are as follows:
$ dpkg --list "libghc6-h*"
