Where can I get "Main.dll_o" and "PrelMain.dll_o"?

I run ghc under cygwin WinNT. If I compile a simple HelloWorld program as described in the instalation descripton, I get the following error: $ ghc -o main main.hs gcc: D:/Unix/ghc/lib/Main.dll_o: No such file or directory gcc: D:/Unix/ghc/lib/PrelMain.dll_o: No such file or directory Do you know whats wrong? Or where can I get the files? -- Andreas Siglreithmayr mailto:Andreas.Siglreithmayr@sdm-research.de sd&m Research GmbH http://www.sdm.de Thomas-Dehler-Str. 18 , D-81737 Muenchen, Germany Tel +49 89 63812-917 Fax -150
