Description Christian Krause 2010-12-19 16:20:17 UTC

Description of problem:
The RAWHIDE version of gtkhtml3 has a changed API with respect to older releases:

--- /tmp/gtkhtml-embedded.h     2010-12-19 17:11:11.000000000 +0100
+++ libgtkhtml-3.14/gtkhtml/gtkhtml-embedded.h  2010-11-08 10:14:45.000000000 +0100
@@ -54,7 +54,7 @@
         GtkBinClass parent_class;
 
         void (*changed)(GtkHTMLEmbedded *);
-        void (*draw_gdk)(GtkHTMLEmbedded *, GdkPixmap *, GdkGC *,
+        void (*draw_gdk)(GtkHTMLEmbedded *, cairo_t *,
                          gint, gint);
         void (*draw_print)(GtkHTMLEmbedded *, GtkPrintContext *);
 };

However, gtkhtml3-3.91.3-1.fc15 still announces itself using the same pkgconfig file gtkhtml-editor-3.14.pc and it uses also the same SONAME in the library.

That's causing problems with projects compiling against gtkhtml3 and leads to  FTBFS issues ([1]) and is considered by upstream as bug in gtkhtml3 ([2]).

Version-Release number of selected component (if applicable):
gtkhtml3-3.91.3-1.fc15

How reproducible:
100%

If a library breaks its API it should at least bump the SONAME and probably announce itself using a different API version via pkgconfig.

This will be fixed with an update to 3.91.4, which will happen some time today. Thus I'm closing this.
