    warning: empty body in an if-statement ??

    Hello - I checked the FAQ/searched site but didn't find anything about this...

    After compilation, I get a warning - warning: empty body in an if-statement but if I look at the if statement, it is all filled out exactly like this:

    Code:
    if(condition)
      function_name(exp_parameter1, exp_parameter1);
    So, how is it even possible to see this warning? What is missing?

    I am on a Linux machine btw.

    Thanks!

    The most likely scenario is that you have by mistake put a semicolon like this:
    Code:
       if (condition);
          ...
    Another possibility is that your function_name is not a function name, but rather a macro that expands to nothing when you compile it.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
