In what module does the following utility macro:
#if defined( __GNUC__ )
#define BOOST_PRAGMA_MESSAGE_IMPL_1( x ) _Pragma( #x )
#define BOOST_PRAGMA_MESSAGE( x ) BOOST_PRAGMA_MESSAGE_IMPL_1( message(
x ) )
#elif defined( _MSC_VER )
#define BOOST_PRAGMA_MESSAGE_IMPL_2( x, f, ln ) __pragma( message( f "(" #ln
"): note: " x ) )
#define BOOST_PRAGMA_MESSAGE_IMPL_1( x, f, ln )
BOOST_PRAGMA_MESSAGE_IMPL_2( x, f, ln )
#define BOOST_PRAGMA_MESSAGE( x ) BOOST_PRAGMA_MESSAGE_IMPL_1( x, __FILE__,
__LINE__ )
#else
#define BOOST_PRAGMA_MESSAGE( x )
#endif
belong?
Use:
BOOST_PRAGMA_MESSAGE( "something" )
MS output:
.\testbed.cpp(10): note: something
g++ output:
testbed.cpp:10:35: note: #pragma message: something
BOOST_PRAGMA_MESSAGE( "something" )
