• Microsoft Visual FoxPro for Windows, version 3.0
• Microsoft FoxPro Library Construction Kit, versions 2.5, 2.5a
• Microsoft FoxPro for MS-DOS, versions 2.5, 2.5a
• Microsoft FoxPro for Windows, versions 2.5, 2.5a

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
        };
