MakeDrvr

When you ask Visual Studio to build your driver, the batch file MakeDrvr.bat, listed in Listing 4.4, is run. This is always passed at least four parameters: the DDK base directory, the source drive, the source directory, and the build type ("free" or "checked"). Any further arguments are passed straight to build.

MakeDrvr first does some basic checks on the parameters that are passed. It then calls the DDK setenv command to set up the environment variables correctly for the build target, changes directory to the source drive and directory, and finally calls build. The –b build option ensures that the full error text is displayed. The –w option ensures that the warnings appear on the screen output, so that Visual Studio can find them in the build Output window.

The screen output of the MakeDrvr command file appears in the Visual Studio Output window. You can then use F4 as usual to go the next error or warning.
