BUG: LNK2001 When Building Applications for MIPS Palm-size PC That Use Float Comparisons (222005)

The information in this article applies to:

Microsoft Windows CE Toolkit for Visual C++ 6.0

This article was previously published under Q222005

SYMPTOMS

Building a MIPS-based Palm-size PC application that uses floating-point comparisons may generate errors similar to the following:

project.obj : error LNK2001: unresolved external symbol __ltd
project.obj : error LNK2001: unresolved external symbol __gtd
project.obj : error LNK2001: unresolved external symbol __eqd

CAUSE

The new version of the MIPS compiler for the Palm-size PC incorrectly makes calls to floating-point comparison functions in later versions of the Windows CE C run time.

RESOLUTION

Use the /QMOC switch to call the earlier versions of the Windows CE floating-point comparison functions.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
