INFO: /Zg Not Designed for Use with .CPP or .CXX Files

• The Microsoft C/C++ Compiler (CL.EXE) included with: - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++ for Windows, versions 1.0, 1.5, 1.51, 1.52 - Microsoft Visual C++ 32-bit Edition, versions 1.0, 2.0, 2.1, 4.0

If you specify the /Zg compiler option switch when compiling a file with the .CPP or .CXX file extension, the compiler may generate a large number of function prototypes. If the number of prototypes is very large, a null pointer assignment, run-time overflow, or other error can occur. This behavior varies depending on the amount of memory available to the compiler.

The /Zg option is not designed for use with .CPP or .CXX files. It is designed to generate function prototypes only for .C files.

Sample Code

   /*
    * Compile options needed: /Zg
    */

   #include <iostream.h>

   void main()
   {
      cout << "Hello out there";
   }
