The first thing I noticed is that RUNGHC looks for a DLL called "png.dll" (which it doesn't find and then bails out with an error), while the executable build with GHC uses the correct "libpng3.dll". When I rename the libpng3.dll into png.dll, RUNGHC goes a bit further but then fails with an "unknown symbol". Obviously I did something wrong in my Cabal script, but I have no idea what it is.
There seems to be a big difference when it comes to linking between of GHCi and GHC . Any guidelines on what to do in cases like the one above?
We had a similar problem with Takusen and ghci on Windows, where the PostgreSQL client dll is called libpq.dll, rather than pq.dll. We also solved it by copying pq.dll to libpq.dll. The extra-libs option is pq, rather than libpq. That fixed it for us, so I don't know why yours is still failing. Perhaps you can post a link to the src? Alistair
