Description btb 2003-09-02 22:59:04 UTC 
Using debian's gcc (a prerelease of 3.3.2), compilation fails with this error:

../../libgnomeui/libgnomeuimm/app-helper.h: In member function `GnomeUIInfo* 
   Gnome::UI::Items::Array<T_Info>::gobj() const [with T_Info = 
   Gnome::UI::Items::SubTree]':
app.cc:107:   instantiated from here
../../libgnomeui/libgnomeuimm/app-helper.h:265: error: `GnomeUIInfo' is an 
   inaccessible base of `Gnome::UI::Items::Info'

I can currently workaround this by using a c-style cast instead of static_cast:

--- libgnomeuimm1.3-1.3.17.orig/libgnomeui/libgnomeuimm/app-helper.h
+++ libgnomeuimm1.3-1.3.17/libgnomeui/libgnomeuimm/app-helper.h

 };

I don't think this is a duplicate of #121308 because it applies to
1.3, not 1.2.  The problem is the same, though.
Comment 3 Murray Cumming 2003-09-04 07:39:32 UTC 
Oh, sorry. I guess it might be better to change
class Info : protected GnomeUIInfo
to
class Info : public GnomeUIInfo,
with a comment about the cast there.
I don't know whether this is a true compiler error though.

Let's do this quick if necessary, because I was about to releas 2.0.0.
Comment 4 btb 2003-09-04 18:12:52 UTC 
I suspect a gcc bug, but I'm a little out of my league there.

Changing protected to public works for me, no c-style casting necessary.
