## SYMPTOMS

In Microsoft Visual C++, the .CPP extension can cause errors when it is used to create a .PLB or .FLL file with the FoxPro 2.5 Library Construction Kit (LCK).
For example, using the .CPP extension to create a .FLL file (FoxPro for Windows library) can cause the error "<path>\PROAPIML.LIB (c:\dosdev\source\winapi16.c) : error L2029: '_FoxTable' : unresolved external", where <path> is the path to PROAPIML.LIB.

## RESOLUTION

To avoid the error, do one of the following:

- Rename the program to have a .C extension. -or-
- Declare FoxTable as external, as follows:

          extern "C" FoxTable _FoxTable =
          {
             (FoxTable FAR *) 0, sizeof(myFoxInfo) /
                sizeof(FoxInfo), myFoxInfo
          };
