Configuring Win32-2.1... Warning: No 'build-type' specified. If you do not need a custom Setup.hs or ./configure script then use 'build-type: Simple'. Warning: 'include-dirs: include' directory does not exist. setup: Missing dependencies on foreign libraries: * Missing (or bad) header file: HsWin32.h * Missing C libraries: user32, gdi32, winmm, kernel32, advapi32 This problem can usually be solved by installing the system packages that provide these libraries (you may need the "-dev" versions). If the libraries are already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are. If the header file does exist, it may contain errors that are caught by the C compiler at the preprocessing stage. In this case you can re-run configure with the verbosity flag -v3 to see the error messages. cabal: Leaving directory '/tmp/cabal-tmp-25853/Win32-2.1' Failed to install Win32-2.1 cabal: Error: some packages failed to install: Win32-2.1 failed during the configure step.
