Line 25 of /usr/include/wx-2.6/wx/gtk/glcanvas.h in the wxGTK-devel package is: #include <GL/glu.h> This is pulling in a header file from libGLU-devel, hence it should be a dependency of wxGTK-devel. It also pulls in headers from libGL-devel, but since libGL-devel is itself a dependency of libGLU-devel, libGL-devel will not be an issue if a libGLU-devel dependency is added.
Okay. Will add this next time I update.
OK, but please bear in mind that packages using this are having to work around the problem by buildrequiring libGLU-devel themselves at the moment (e.g. see Bug #193531).
*nod*
Okay, since this was so trivial I just went ahead and did it. The update is building now.
