ERR: "Unresolved Reference" Using C 7.0 Makefile with 2.5 LCKID: Q105596 The information in this article applies to:
SYMPTOMSWhen you are creating a library using the FoxPro 2.5 Library Construction Kit (LCK), numerous errors occur during the compiling and linking process. One of these errors is "Unresolved Reference." CAUSEThe error occurs because the C compiler (Microsoft C 7.0 in this case) cannot find the library, object, or header file that is displayed in the error. For example, the compiler may not be able to find the LIBW.LIB file that is referenced in the makefile provided with the LCK for use with Microsoft C 7.0. This file, part of the Microsoft Windows Software Development Kit (SDK), is a library file containing Windows functions that can be called in a FoxPro for Windows .FLL library. When you are using the Microsoft C 7.0 makefile provided with the LCK to produce an .FLL library, the "Unresolved Reference" error message will occur if the SDK is not installed. RESOLUTIONTo track down the cause of the "Unresolved Reference" error, do the following: 1. Check for the existence of the file that contains the function or library reference that is causing the error. 2. Check the MS-DOS PATH statement to make sure the file or library can be found at compile and link time. 3. Make sure all MS-DOS SET environment variables needed by the compiler are set correctly in the AUTOEXEC.BAT file. 4. Make sure the filename listed in the makefile is spelled correctly. MORE INFORMATIONA makefile is used to compile and link a C library or executable. As mentioned above, there is a sample makefile for use with C 7.0 in conjunction with the LCK to create C libraries to interface with FoxPro for Windows. The libraries created by the LCK have an extension of .PLB for FoxPro for MS-DOS and .FLL for FoxPro for Windows.
