That might be best.
I in general remove the whole build dir contents, to test cmake stuff, and
clear the cache inside
cmake-gui.
If i do that, it passed that part without problems somehow.

Why not?? A wxIcon is returned from GetIcon(size), and that is a temporary i
think.
But i am not good at such thinks.

Did not help.
But the next does ( it stores/copies the return wxIcon first ):
static wxIcon icon = self->GetIcon(size);
const wxIcon* returns = (const wxIcon*) &icon;
or:
wxIcon icon = self->GetIcon(size);
const wxIcon* returns = (const wxIcon*) &icon;

Done that, seems to help.

I see.

If you mean the MediaPlayer example, yes, and it works. I do not see another
example, so i think
that is the only one.
With all the advice, i now get until here (see end this mail). The library
-lgstinterfaces-0.10 is
missing to link too? If i add it by hand as -lgstinterfaces-0.10 down here, on
the commandline, it
links.
In aps/CMakeLists change this, also works:
LINK_LIBRARIES
#wxLuaBindLib
${wxLuaBind_ALL_LIBS}
wxLuaSocketLib
wxLuaDebugLib
wxLuaLib
LuaLib
gstinterfaces-0.10
${wxWidgets_LIBRARIES}
With that i can compile completely! :-)
But -Wno-deprecated did not make much a difference for all the warnings??
