Compiler Warnings

[Steve Cookson]

Hi Guys,

I have recently been getting a lot of compiler warnings and notes every
time I install many things, including wxWidgets. I have recently
upgraded to Kubuntu 14.04 LTS and it been around for at least one
release that. An example follows at the end of this email. I imagine
that the compiler has been upgrade and is now more stringent about some
check, or indeed, I suppose it could indicate a compiler installation
problem.

Do you have a view?

Regards,

Steve.

This is not a compiler installation problem, the warnings seem quite clear
to me: Wx.c code uses deprecated methods in wxWidgets. It needs to be
modified (probably by using explicit wxCHECK_VERSION() checks as it must
compile under both 2.8 and 3.0) to get rid of them.

Hi Vadim,

Thanks for this.

Is there a simple piece of code that be inserted into this that we could
all do a few of. There are upwards of 4,000 downloads a week of 3.0.0.
If a few enthusiasts did one or two a day it would soon be cleared.

I seem to be doing four or five compilations a day at the moment as I
battle with converting my 2.8.11 to 3.0. I'd upgrade the files I have
to compile manually (like mediactrl and richtextbuffer etc).

Regards

Steve.

Most of the places where things have been marked as deprecated have a
strong hint of what to use instead, e.g.: in menu.h there is the
following code:

// get or change the label of the menu at given position
// Deprecated in favour of SetMenuLabel
wxDEPRECATED( void SetLabelTop(size_t pos, const wxString& label) );
// Deprecated in favour of GetMenuLabelText
wxDEPRECATED( wxString GetLabelTop(size_t pos) const );

The time consuming bit is not so much tracking down and replaced the
offending code, i.e. where this items are used, it is *testing* the
modifications.
