When you embed an .xpm file to some C++ project in Linux, you will get tons of harmless warnings.
warning: deprecated conversion from string constant to ‘char*’
You can disable such warning in the project on global basis, by adding -Wno-write-strings to the g++ command line arguments.
But, there a better way, to disable warnings for a per file basis using pragma directives in g++:
#pragma GCC diagnostic ignored "-Wwrite-strings"
#include "logo.xpm"
#pragma GCC diagnostic warning "-Wwrite-strings"
#include "logo.xpm"
#pragma GCC diagnostic warning "-Wwrite-strings"
List of GCC options to request or suppress warnings can be found on Red Hat website.
Visual Studio also supports similar pragma directives to disable particular warning messages.
