BUG: Can't Build Nec73pcm\Drv DDK Sample Without Vxdpipe.h

• Microsoft Windows Device Development Kit (DDK) for Windows 95

SYMPTOMS

The PC 9800 DDK Multimedia Sample in the \Mmedia\Samples\Nec73pcm\Drv directory does not build correctly. During the compile, the Vxdpipe.h file in the Include path cannot be found. NMAKE returns and displays errors stating that it can't find certain Include files.

CAUSE

The Ddkenv.bat file when run sets up an additional directory where Include files can be found. The directory is specific to the module being compiled. In the case of MMEDIA, it adds the \Ddk\Mmedia\Inc directory to the the Include set statement. This directory does not exist; the files are actually in \Ddk\Mmedia\Samples\Include.

RESOLUTION

Create a subdirectory named Inc in \Ddk\Mmedia. Copy the files from \Ddk\Mmedia\Include to \Ddk\Mmedia\Inc.
