Remove function in Release build only

Is there any methods to remove a line of code from a Release build, but leave it in the Debug build without ugly #if statements?

For example, is the开发者_JAVA百科re some way to achieve the equivalent of the below code without using all these if statements?

#if DEBUG
    Log.Log("I am in debug mode");
#endif

If I have a conditional, run-time check in the Log.Log function, then the string "I am in debug mode" will be preserved within my compiled executable, which is exactly what I do not want.

Define another macro in a common, shared header.

#ifdef DEBUG
#define LOG(m) Log.Log(m);
#else
#define LOG(m) do {} while(false);
#endif

Then replace your calls to Log.Log with LOG.

You'll ultimately need a preprocessor conditional somewhere, but you could apply it "upstream" in some shared header if you want to keep your application code clean. In that case, you'd have something like

#if DEBUG
   #define DebugLog(m) Log.Log(m);
#else
   #define DebugLog(m)
#endif

in the header associated with Log, and instead of calling Log.Log(m) inside a preprocessor conditional in your application code, you'd just call DebugLog(m). In a Debug build, the macro would expand to Log.Log(m), but otherwise it would just disappear entirely.

Have your Log.Log function #ifdef'd based on the build. So in DEBUG, it logs stuff, and in RELEASE, it's a no-op. For example:

namespace Log
{
  void Log()
  {
  #if DEBUG
    //Insert logging code here.
  #endif
  }
}
