GCC #pragma message ignored

I am trying to display a compile-time message in GCC, via

#pragma message "hello world"

But when I compile with -Wall it gives the warning

warning: ignoring #pragma message

I'm using GCC 4.2.1 on Mac OS X 10.6.8 (Snow Leopard).

Why isn't it displaying the message? How can I make it display the message?

Solution

  • If you read the correct documentation, you'll find that #pragma message isn't supported in GCC 4.2.1.
