wxWidgets Debug Alert in Release-Build

[Karl Karpfen]

Hi,

when I start my application it shows up an assert with an wxWidgets Debug Alert window. The reason for this alert is clear (and will be removed). More amazing for me: this happens in release build! So has there changed anything in wxWidgets 3 which lets these alerts pop up? As far as I know all related libraries are build as release and nowhere the _DEBUG option is set. So are there any other conditions that could cause this alert window?

Thanks :-)

You did not mention your OS, If you are on Windows using the MinGW suite, I use these steps to build my wxWidgets:

http://codelite.org/Developers/BuildingWxWidgetsWin

Following the above steps builds wxWidgets in debug_level=0

However, I think that passing -DNDEBUG when building your application should be enough for removing these kind of popup alerts

This seems to be the solution - thanks!

OK, I don't get it working. When I set a

#define wxDEBUG_LEVEL 0

at the very first beginning the assert dialogue is still there. When I try it with

#include <wx/app.h> 

wxDISABLE_DEBUG_SUPPORT()

I get several compiler errors:

'int wxDisableAsserts(void)' : overloaded function differs only by return type from 'void wxDisableAsserts(void)'

'wxDisableAsserts' : redefinition; different basic types

You need to rebuild wxWidgets with wxDEBUG_LEVEL=0. However I don't
recommend doing it unless you really, really need to make the smallest
possible binaries. It's much better to leave the debugging checks in and
disable them in the production version but still be able to enable them if
necessary.

wxDISABLE_DEBUG_SUPPORT() must be inside your main() function. Also, you
usually don't need to call it explicitly, the standard solution is to
define NDEBUG for your release build, then this will be done for you by the
standard wxIMPLEMENT_APP() macro.

OK, I'll try that - thanks!
