Getting base name of the source file at compile time

Question

I\'m using GCC; __FILE__ returns the current source file\'s entire path and name: /path/to/file.cpp. Is there a way to get just the file\'s name file.cpp<

Answer 1

What does your error logging macro do? I would presume at some point the macro eventually calls a function of some kind in order to do the logging, why not have the called function strip off the path component at runtime?

#define LOG(message) _log(__FILE__, message)

void _log(file, message)
{
  #ifndef DEBUG
  strippath(file); // in some suitable way
  #endif

  cerr << "Log: " << file << ": " << message; // or whatever
}
