Hi, Do you take bug reports also for School of Expression code? Anyway, I have a problem with the School of Expression example code for X11 (soe.tar.gz) when installing on a Solaris 2.7 system. Unpacking is no problem. Then I install the graphics library according to the Install file, giving local paths: make -C graphics-2.0.4/lib/x11 system=SunOS X_dir=/usr/X hugs_install=/sw/local/bin/hugs This also seems to run smoothly. But when I try the suggested test example, the following happens: blr.idt.mdh.se>runhugs -Pgraphics-2.0.4/lib/x11: graphics-2.0.4/demos/HelloWorld.hs runhugs: Error occurred Reading file "graphics-2.0.4/demos/HelloWorld.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsUtils.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsCore.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsEvent.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsKey.hs": Reading file "graphics-2.0.4/lib/x11/X.hs": Reading file "graphics-2.0.4/lib/x11/Xlib_StdDIS.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/exts/Int.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/exts/Bits.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/exts/Int.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/exts/Word.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/exts/Addr.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/Monad.hs": Reading file "/sw/local/pkgs/hugs-98/share/hugs/lib/exts/Foreign.hs": Reading file "graphics-2.0.4/lib/x11/Xlib_StdDIS.hs": Reading file "graphics-2.0.4/lib/x11/X.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsKey.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsEvent.hs": Reading file "graphics-2.0.4/lib/x11/GraphicsWindow.hs": Reading file "graphics-2.0.4/lib/x11/Xlib.hs": Reading file "Exception": ERROR Exception - Unable to open file "Exception" I just cannot find the cause of this. Is it a known problem? Do you know how to work around it? I don't suspect Hugs, it's working fine otherwise on our system. Best regards, Björn Lisper
