#1132 fixed 0.9.13 fails to build on PPC/Linux/ghc6.8.3 somebody guest

Reported by guest, 9 years ago.


Here's a build log:

Scroll down to near the end and you'll see this:

/usr/bin/ghc-6.8.3 +RTS -RTS -c tools/c2hs/toplevel/C2HSConfig.hs -o tools/c2hs/toplevel/C2HSConfig.o -O -fffi -fvia-C '-#include<c2hs_config.h>' -itools/c2hs/base/admin:tools/c2hs/base/errors:tools/c2hs/base/general:tools/c2hs/base/state:tools/c2hs/base/syms:tools/c2hs/base/syntax:tools/c2hs/c:tools/c2hs/chs:tools/c2hs/gen:tools/c2hs/state:tools/c2hs/toplevel -package-conf package.conf.inplace -hide-all-packages -package base -package haskell98 -package pretty -package containers -package array

make[2]: *** [tools/c2hs/toplevel/C2HSConfig.o] Error 255

This looks like bad compiler output, as opposed to a problem with gtk2hs itself, but I wanted another pair or three of eyeballs to be sure.

The build system I'm using is Fedora's batch system, so it's nearly impossible for me to give a more useful reproduction :-(

#1254 fixed API links on documentation page old somebody guest

Reported by guest, 6 years ago.


The API links on the documentation page are for version 0.11.

It would probably be better if they pointed to the hackage auto-generated docs: ...

#1108 fixed Add Eq instances for all of Graphics.UI.Gtk.Gdk.Enums somebody guest

Reported by guest, 9 years ago.


None of the enumerations in Gdk.Enums are instances of Eq, which makes it cumbersome to check for certain events. For example, I wanted to keep track of the fullscreen state of a window with the following code:

ref <- newIORef False
onWindowState win $ \WindowState { eventWindowState = state } -> do
    writeIORef ref (WindowStateFullscreen `elem` state)
    return True

However, writing the code this way requires an Eq instance; workarounds require either manually defining one or using pattern matching, which is cumbersome because state is a list of WindowState values.

It would be trivial to add deriving (Eq) to these enumerations (and also Read/Show, for debugging purposes).
