The following might be of special interest to people who are using Paul Hudak's Haskell textbook for teaching and or study and would like to run the SOE graphics examples with GHC - or if you simply want to have an X-based graphics library for an application. GHC's source distribution contains the two library packages `xlib' and `HGL' (Alastair Reid's Haskell Graphics Library) as part of hslibs, which are not by default built and installed. For our local teaching needs at the University of New South Wales, we have produced a patched version of GHC 5.02.1 that includes the aforementioned libraries in a working form. Haskell modules can be compiled or linked against these libraries, by providing the command line options `-package xlib' and `-package HGL', respectively (or you can specify them using the :s command in the interpreter). RPM packages for x86 GNU/Linux based on glibc 2.2 (eg, RedHat 7.x) containing GHC 5.02.1 including the xlib and HGL packages are available as ftp://ftp.cse.unsw.edu.au/pub/users/chak/jibunmaki/i386/ghc-5.02.1-graphics.1.i386.rpm ftp://ftp.cse.unsw.edu.au/pub/users/chak/jibunmaki/i386/ghc-prof-5.02.1-graphics.1.i386.rpm ftp://ftp.cse.unsw.edu.au/pub/users/chak/jibunmaki/i386/ghc-doc-5.02.1-graphics.1.i386.rpm with the source RPM at ftp://ftp.cse.unsw.edu.au/pub/users/chak/jibunmaki/src/ghc-5.02.1-graphics.1.src.rpm The source RPM contains a patched source tar ball and build instructions in the form of an RPM .spec that may be used to build the packages for other Linux distributions and on other Unix systems. (NB: GreenCard need not be installed to build this package, as a throw-away version of GreenCard is included in the tar ball - ie, it is used in the build process, but not installed.) Cheers, Manuel
