Should be, but isn't, unfortunately. The Setup.hs file includes some code defining configPG etc, but there's nothing I can see for the user control how it works. Maybe something in the cabal infrastructure handles this, but I've not had time yet to dive into the cabal documentation on the hope of finding something.
Just a brief note to let people on the list know that, with a lot of extremely patient help from Alistair Bayley, I have managed to resolve the issues I was having. The fundamental issue I was hitting was that I was treating GHC as an interpreted system, rather than a compiler/linker. I was therefore not thinking about the errors I was seeing as I would if I hit (say) a C link error. To summarise, the following works fine: To install Takusen, make sure that an Oracle home is in your PATH. You don't need PostgreSQL or sqlite. Your Oracle install can be simply a client build - all you need is oci.dll, not the full OCI development package. runhaskell Setup.hs configure runhaskell Setup.hs build runhaskell Setup.hs install That's it, and it works fine. To build a program, you need to do ghc --make db.hs -o db D:\Oracle\Ora92\bin\oci.dll (put the path to your oci.dll here). This compiles your program, and links it with oci.dll to get the Oracle externals resolved. Runhaskell doesn't seem to work, as it tries to link all the DB backends at runtime, regardless of whether you use them. That really is all there is to it. Arguably, the error messages you get when you mess up bits of this aren't too helpful, but if you've ever seen a C++ compilation fail with compile or link errors, you'll know not to expect much here (or at least you should!) GHC is certainly no worse than that. Once again, thanks to Alistair for his patience. Now I'll go off and reproduce my success on a clean environment just to be sure, and then write up what I've learnt for the Wiki and the Takusen readme.
