Package: libgtkmm-4.0-dev
Version: 4.22.0-1
Severity: important
File: gtkmm
X-Debbugs-Cc: [email protected]
Dear Maintainer,
When compiling software that includes a gtkmm header file, using g++, the
software fails to compile due to this error:
/usr/include/gtkmm-4.0/gdkmm/cursor.h:30:7: error: conflicting declaration
‘using GdkCursorClass = struct _GdkCursorClass’
In file included from /usr/include/glib-2.0/gobject/gobject.h:26,
from /usr/include/glib-2.0/gobject/gbinding.h:31,
from /usr/include/glib-2.0/glib-object.h:24,
from /usr/include/glibmm-2.68/glibmm/class.h:21,
from /usr/include/glibmm-2.68/glibmm/objectbase.h:21,
from /usr/include/glibmm-2.68/glibmm/object.h:29,
from /usr/include/gtkmm-4.0/gdkmm/clipboard.h:25,
from /usr/include/gtkmm-4.0/gtkmm/widget.h:32:
/usr/include/gtk-4.0/gdk/gdkcursor.h:38:1: note: previous declaration as
‘typedef struct GdkCursorClass GdkCursorClass’
This seems to hold for including most of the header files, in this case e.g.
the widget.h file:
[..]
In file included from /usr/include/gtkmm-4.0/gtkmm/widget.h:33,
from /usr/include/gtkmm-4.0/gtkmm/box.h:26,
[..]
This affects e.g. the build of the aoflagger package (and probably many
others), which no longer builds against the current version of
libgtkmm-4.0-dev.
Regards,
André

I believe this issue is fixed in gtkmm4.0 4.24.0-2 which is in
Unstable and should migrate to Testing in the next day or so. Sorry
for the inconvenience.
Thank you,
