Hmmm, I just now came across this: "I'm not confident that creating Haskell DLLs is working at the moment. Has anyone else done it?" I have. Or rather, I haven't. The example in Section 11.4 of the User's Guide doesn't work. The call to "startupHaskell()" hangs forever (or as long as I'm willing to wait). It works fine when the exact same call to startupHaskell is linked statically. "Trouble is, there isn't yet a critical mass of DLL users to be sure that it works and stays working. Which is a bit of a chicken and egg problem. Windows programmers unite!" Is two a critical mass? -- Kevin S.
