Hi All,
I want to add some customized output information in Arduino IDE when compiling the code written by me.
I tried #pragma message("hello"). It dispalyed nothing.
Can anybody know it?

Thanks,

Steve

Code:

#error Bad news, dude.

#warning Something fishy.

Another possibility (requires the condition to reduce to a compile-time constant)...

Code:

static void OutputsErrorIfCalled( void ) __attribute__ (( error("Unexpected condition encountered.") ));

void loop( void )
{
  if ( true )
  {
    OutputsErrorIfCalled();
  }
}

It works!
Thanks for your help.
