Are there any significant pro's and con's of driver build using native
windows ddk build utility on windows platform over cygwin build? does whql
expect any kind of specific build process?

thanks

Well since Microsoft changes things and getting all the parameters correct
for compiling and linking drivers is a pain, why would you use anything
other than what Microsoft supports. I've consulted to firms contracting out
drivers to 3rd parties and I tell them to reject any driver that has not
been built with the standard DDK build environment.

Seriously, Windows device driver writing is a complex task to begin with,
why in the world would you add potential additional problems by not using
the standard environment, especially since Microsoft gives away for the
price of shipping the DDK with everything you need.

I'm not sure exactly what you mean by "ddk build utility...over cygwin
build". The ddk build utility is going to use nmake and is going to
expect specific environment variables to be set and is going to assume
that it is using the microsoft compilation toolset. None of that
correlates to the cygwin toolset. On the other hand if you are using
cygwin's version of make as a front end to drive a build process that
includes invoking the ddk build utility, that might work, depending on
how you arrange to invoke ddk build.

As Don pointed out, you are basically asking if it is ok to hurt
yourself, and the answer is, if you really must hurt yourself, and you
have good reason for doing so, then go ahead.

WHQL has no idea how you built your driver.

Nobody will help you in resolving any issues with CygWin build.
Also GCC is not compatible with MS's compiler in #pragma commands.

So, use the suggested tools
