I need to compile a .cpp file into my Win2k intermediate driver. Is
this possible? It compiles fine, but when it starts to link I get a
bunch of errors, numero uno is “unresolved external symbol : void
__cdecl operator delete(void *)”. What do I need to do to get this to
link together?
Thanks,
John

You have to be very careful about C++ runtime support. The fact that you
have an unresolved reference to the global delete operator indicates that
your .cpp file assumes the existence of C++ runtime support not provided by
the NT kernel programming environment.
That’s the bad news, the good news is that there is help, and its free. See
my website resource page for a free C++ kernel runtime library. Also Numega
(www.compuware.com) has a similar package, also free.

It seems to me that the code written in the cpp file uses new and
delete, but that’s the extent of the “cpp-ness” of the code. There are
no classes, etc., just the use of new and delete. Do I still need to
use the C++ kernel runtime library?

Yeah, 'cause like I said, there is NO ZERO NADA kernel c++ runtime support.
At the top of the list of ‘no kernel runtime support’ would be ‘new’ and
‘delete’. Just grab my or numega’s kernel c++ runtime (or is that rumtime)
library.

Easiest approach is to remove new/delete dependency by using the relevant

This will be much more efficient anyway.

It’s an easy step to override system new and delete functions with your own.
You don’t need to change the source, just write two new functions.
Hope this helps,

If u are not using New and Delete for Allocting and De-allocating memory it is
not required.

You’re not missing anything, given those parameters.
My point was that it is worth including a C++ runtime when to port C++ code to C
would require many hours of work translating classes and C++ additions to straight
C. BUT, if the only thing you’re using is new/delete – it’s easier to just
replace those calls as appropriate – rather than going through a learning curve
of how to get C++ running in the kernel. I don’t take any particular viewpoint as
to whether “C++ in the kernel is bad and evil” or otherwise – each case should be
judged on its own pros/cons. I envisioned a C++ runtime dragging in a whole bunch
of runtime code that was not likely to be used (when the only extensions used are
new/delete) – and usually that does not help efficiency. There’s also the
question of support – I’d rather support my own code, not someone else’s runtime
– It’s hard enough dealing with bugs in the kernel, MS runtime bugs, let alone
another 3rd party’s – but that comes down to personal preference.

Well, and do you have SMP machine? I presume this choice isn’t on uni CPU
machine because has no sense there.

Are you looking at TaskMgr on an SMP system? Affinity doesn’t apply on a UP
system, hence doesn’t appear on the TaskMgr context menu.

Hi,
I think some of the libraries that are required to link with are missing /
not mentioned.
"unresolved external symbol : " - this Linker error occurs usually when a
required library
is missing. check out for the library required by ur functions.
Wish u good luck,
Ashok.

Subject: [ntdev] compiling in cpp file
I need to compile a .cpp file into my Win2k intermediate driver. Is
this possible? It compiles fine, but when it starts to link I get a
bunch of errors, numero uno is “unresolved external symbol : void
__cdecl operator delete(void *)”. What do I need to do to get this to
link together?
Thanks,
John
