Modifying DDKENV.BAT to Build 16-Bit Multimedia Drivers

• Microsoft Win32 Device Driver Kit (DDK) for Windows 95, version 4.0

SUMMARY

The Windows 95 Device Driver Kit (DDK) contains a number of sample multimedia device drivers. Many of these drivers contain both a 16-bit DRV component and a 32-bit VXD component. In order to build the 16-bit multimedia driver components, you can run the following three batch files in the order listed. Note the two parameters passed to ddkenv.bat:

• new-vars.bat, typically located in the \masm611\binr directory.
• msvcvars.bat, typically located in the \msvc\bin directory (use a 16- bit version of Visual C++, such as 1.52).
• ddkenv.bat 16 mmedia, typically located in the \ddk directory.

   :ENVIRON16
   REM *** add the location of your 16-bit environment here ***
   set WIN16=TRUE
   set include=%ddkroot%\%2\inc;%ddkroot%\inc16;%sdkroot%\inc16;
   %_include%;%ddkroot%\inc32;%sdkroot%\include
   set lib=%ddkroot%\lib;%sdkroot%\lib16;%_lib%
   path=%ddkroot%\%2\bin;%ddkroot%\bin;%sdkroot%\binw16;%sdkroot%\bin;
   %_path%
   prompt Windows 95 16-bit %2 build$_%_prompt%
   goto EGRESS

Following is the modified "set include=" line:

   set include=%ddkroot%\%2\inc;%ddkroot%\inc16;%sdkroot%\inc16;
   %sdkroot%\include;%_include%;%ddkroot%\inc32;
