BUG: C 6.0 Symbol STKHQQ Not Defined in OLDNAMES.LIB

The information in this article applies to:

• The C Run-time (CRT), included with:

      - Microsoft C/C++ for MS-DOS, version 7.0
      - Microsoft Visual C++ for Windows, versions 1.0 and 1.5
  

SYMPTOMS

The OLDNAMES.LIB file was included in C/C++, version 7.0 and later to maintain compatibility with names included in C version 6.0 object modules. The symbol STKHQQ, is part of the stack checking routine in C, version 6.0, but it is not defined in OLDNAMES.LIB. Therefore, the linkers included with C/C++, version 7.0, and Visual C++ will generate error message L2029, "unresolved external", for STKHQQ if C version 6.0 objects modules are used.

RESOLUTION

Rebuild the C version 6.0 object module with the later version of the compiler that you are using.

NOTE: If the object module is from a third party library, contact the provider of the library and get an updated library which is not based on C6. Alternatively, a corrected version of OLDNAMES.LIB can be created from the C Run-Time source. The source to OLDNAMES.LIB is OLDNAMES.ASM in the CRT\HELPER directory. Add the following line:

       alias    <STKHQQ>   = <_STKHQQ>
