I decided to have a play with the win32 bindings in the hierarchical libraries. The attached program built with ghc --make fails to link with these errors: test.o(.text+0x1c2):fake: undefined reference to `GraphicsziWin32ziMisc_messageB ox_closure' test.o(.text+0x255):fake: undefined reference to `__stginit_GraphicsziWin32ziMis c_' test.o(.data+0x3c):fake: undefined reference to `GraphicsziWin32ziMisc_messageBo x_closure' How can I get this to build for now, and is it possible to set up the package that comes with the binary windows distribution so that no fix is needed in the future? -- flippa@flippac.org A problem that's all in your head is still a problem. Brain damage is but one form of mind damage.
