PRB: MASM Code Using CMACROS.INC Does Not Build Correctly (100407)
The information in this article applies to:
- Microsoft Windows Software Development Kit (SDK) 3.1
This article was previously published under Q100407 SYMPTOMS
Attempting to build a Windows-based application with MASM code using a
CMACROS.INC header file causes errors to be generated by the macro
assembler.
CAUSE
The CMACROS.INC file is incompatible with the version of MASM being
used.
RESOLUTION
When using MASM version 6.x, use the version of CMACROS.INC that comes
with MASM. When using MASM version 5.1, use the version of CMACROS.INC
that comes with the development product you are using, such as the
Windows Software Development Kit (SDK) or the Windows Device Driver
Kit (DDK).
MORE INFORMATION
MASM has changed considerably from version 5.1 to versions 6.x; the
changes to the assembler include the removal of the second assembly
pass and additions or modifications to the behavior of assembler
directives. A complete list of the differences can be found in the
product documentation of MASM versions 6.0 and later. Because of these
changes, versions of CMACROS.INC compatible with MASM 5.1 are not
compatible with MASM 6.x; likewise, versions of CMACROS.INC compatible
with MASM 6.x are not compatible with MASM 5.1.
Most of Microsoft's development products include a version of
CMACROS.INC that is compatible with MASM 5.1. Use this version of
CMACROS.INC with MASM 5.1. If MASM version 6.0 or later is being used,
use the CMACROS.INC that comes with it instead of the one that comes
with the development product.
