Best solution for Ubuntu!!

std::string getpath() {
  char buf[PATH_MAX + 1];
  if (readlink("/proc/self/exe", buf, sizeof(buf) - 1) == -1)
  throw std::string("readlink() failed");
  std::string str(buf);
  return str.substr(0, str.rfind('/'));
}

int main() {
  std::cout << "This program resides in " << getpath() << std::endl;
  return 0;
}
