500 is a general catch all for server errors. The most likely causes are that you CGI crashed or it output something on stderr.

Obviously the cause of a crash is impossible to tell without the code etc. Often the easiest way to test CGIs is to run them within a script and set up all the important environment variables (eg REQUEST_METHOD, QUERY_STRING etc) prior to execution.

If you are using VC++ or Borlan C++ and similar you can set the variables up in the environment and run the CGI in debug.

For obvious reasons I like to start out with something simple,
and here it is.

#include"iostream.h"


void main()
{
      cout <<"Content-type:text/html\n\n";
      cout <<"<html>\n";
      cout <<"<head>\n";
      cout <<"<title>";
      cout <<"CGI Output";
      cout <<"</title>\n";
      cout <<"</head>\n";
      cout <<"<body>\n";
      cout <<"CGI Output\n";
      cout <<"</body>\n";
      cout <<"</html>\n";
}
