PRB: LNK1120 Error Gives You the Number of Unresolved Externals (815650)

/LIBPATH:dir

MORE INFORMATION

For more information about the conditions that cause unresolved external symbols, visit the following MSDN Web site:The symbols that the linker cannot resolve are described with the LNK2001 error message. The LNK2001 error message comes before the LNK1120 error message. You receive the LNK2001 error message for each unresolved external symbol.

Steps to Reproduce the Behavior

1. Paste the following code in Notepad, and then save the file:

   //The prototypes of functions fun1(), fun2() and fun3()
   void fun1(void);
   void fun2(void);
   void fun3(void);
   
   // This is the entry point for this application
   int main(void)
   {
   	fun1();
   	fun2();
   	fun3();
   
   	return 0;
   }

2. Use the following to compile the application:

   cl /c <filename.cpp>

   where filename is the name of the file that you created and saved in step 1.
   
   Note: To compile the program in Microsoft Visual Studio .NET, use the Microsoft Visual Studio .NET command prompt.
   
   To compile the program in Microsoft Visual Studio 6.0 and earlier, run vcvars32.bat from the command prompt.
3. Link the object file as follows:

   Link <filename.obj>

The following linker errors appear at the command prompt:Notice that the LNK1120 error message gives you the number of unresolved external symbols that the linker found.
