Thanks for the tips. Looks like I banged my head against the wall because
of precompiled header woes. Forgot to include “precomp.h” when I added my
new found code to my sources file. Funny (odd, not ha ha) but I did this
last time too! Arrgh.

Hmm… Perhaps your definition of BLOCK_SIZE as 32 isn’t actually being read
beforehand… I usually rerun the compilation with /P /C to generate a .i
file with comments in cases like this, then look at the generated #line
directives to see what source files/lines are actually being processed.

Well, that’s what I thought too.
The errors I’m getting are “macro redefinition” errors. In the example
below for instance, I’ve defined the BLOCK_SIZE to 32, but the compiler is
flagging redefinition errors in the “#if BLOCKSIZE == 16” section.
Specifically, the second occurrence of “locals” is being flagged.
Commenting out the first definition makes it happy. But the compiler
shouldn’t even be looking at this code in the first place if BLOCK_SIZE is
32!

The DDK compiler is (pretty much) the same as the Visual Studio .NET
compiler and implements all the standard preprocessor stuff (you can read
the manuals online at the MSDN site).
A brief scan of the sample you gave looks fine to me; what error are you
getting?

Subject: [ntdev] A question about the DDK compiler and preprocessing
Hi,
I am looking for some documentation about how the DDK (XP SP1) compiler
deals with preprocessor directives and can’t seem to find anything
substantial.
I have inherited some “generic” C code that has been to preprocessor hell
and back so that it can compile on any platform known to man (and then
some). It’s supposed to be an easy drop in set of source code for some
encryption algorithms, but so far I can’t get the compiler to cooperate.
There are all types of things like below where I get macro redefinitions.
I’m relatively new to the DDK compiler and I’ve never done anything this
complex with preprocessor commands. Any help would be appreciated. If I
can make all the conditional compilation work, that would be a dream.
Please don’t tell me I have to do “manual preprocessing” to get this to
work. That will be the nightmare.
Thanks,
Paul
