Huzza. Great work Ben.

Management of shared libs on Windows is going to be a bit of a pain. For the purposes of testing we will want to just modify the %PATH% to include the lib dir containing the dlls. This should be enough for the testsuite, to ensure no regressions. Ian: could you look at this? We'll want all the dlls installed into the ghc lib dir I think (or a subdir if you prefer). Then the testsuite on Windows would need to add that directory to the %PATH% so that executables generated by ghc will be able to find the dlls. Doing things properly will require more work. As Andrew says, Windows doesn't use DLLs in quite the same way as shared libs on Unix. As Neil says we'll most likely have to stick to using static libs by default and using DLLs will be an extra explicit step people do for deployment. The best option is likely going to be making packages into Win32 assemblies (using GUIDs and xml manifests). These can be installed into a subdir of a program installation tree, or they can be installed into a system-wide "SxS" location. The system wide thing allows any program to depend on them by specifying the GUID in their xml manifest. The downside is that only root can install things into the shared global SxS area so it's not as general as -rpath on ELF platforms. > After doing a manual install, all the "dyn" tests in the testsuite run > fine for me. A stripped "hello world" executable is about 10k. Excellent.
