The attached patch fixes a number of issues (mostly unused
variables and ignored return variables) which raise warnings
with gcc 4.6 and cause a build failure if -Werror is also enabled.
ChangeLog:
2011-06-27 Andrew John Hughes <ahug...@redhat.com>
Fix issues with building with -Werror and gcc 4.6.
* native/jni/gtk-peer/GtkDragSourceContextPeer.c:
(Java_gnu_java_awt_dnd_peer_gtk_GtkDragSourceContextPeer_nativeSetCursor):
Remove unused ptr variable and mark env as unused.
(connect_signals_for_widget(GtkWidget*)): Mark w unused and don't set
it.
(Java_gnu_java_awt_dnd_peer_gtk_GtkDragSourceContextPeer_nativeStartDrag):
Remove unused ptr variable.
* native/jni/gtk-peer/gnu_java_awt_peer_gtk_ComponentGraphics.c:
(Java_gnu_java_awt_peer_gtk_ComponentGraphics_initState):
Remove unused width and height variables.
* native/jni/gtk-peer/gnu_java_awt_peer_gtk_GdkRobotPeer.c:
(Java_gnu_java_awt_peer_gtk_GdkRobotPeer_mouseMove):
Check result of XTestFakeMotionEvent call.
(Java_gnu_java_awt_peer_gtk_GdkRobotPeer_mousePress): Likewise for
XTestFakeButtonEvent call.
(Java_gnu_java_awt_peer_gtk_GdkRobotPeer_mouseRelease): Likewise.
(Java_gnu_java_awt_peer_gtk_GdkRobotPeer_keyPress): Use g_message
instead of deprecated g_printerr. Check result of XTestFakeKeyEvent.
(Java_gnu_java_awt_peer_gtk_GdkRobotPeer_keyRelease): Likewise.
* native/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkPopupMenuPeer.c:
(Java_gnu_java_awt_peer_gtk_GtkPopupMenuPeer_setupAccelGroup):
Completely disable code to attach parent, including use of ptr2
and parent argument, and reinstate original FIXME to explain why.
* native/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkVolatileImage.c:
(Java_gnu_java_awt_peer_gtk_GtkVolatileImage_nativeGetPixels):
Remove unused depth variable.
* native/jni/midi-alsa/gnu_javax_sound_midi_alsa_AlsaPortDevice.c,
(Java_gnu_javax_sound_midi_alsa_AlsaPortDevice_run_1receiver_1thread_1):
Check return values and throw an InternalError if a problem occurs.
