[Haskell-cafe] Fwd: Trouble using HDBC-postgres on Windows - can't find libpq.dll

[Justin Bailey]

Well, I answered my own question. Unlike UNIX, specifying a library
without the leading "lib" causes the library to not be found. Not sure
if that's a GHC linking problem or what. Changing the library
requirement to "libpq" in the .cabal file did the trick tho.

I've compiled HDBC 1.0.1 and HDBC-postgresql-1.0.1 under Windows with
a little tweaking. However, when I try to run the tests I get this
error:

  >runghc -package HDBC-postgresql  runtests.hs
  ghc.exe: can't load .so/.DLL for: pq (addDLL: unknown error)

libpq.dll is in my path, and I added the correct paths to the .cabal
file when I built it. Does anyone have an idea what might be the
problem?

Justin

p.s. I have postgres 8.2 installed if that matters.
