c++ - language extension __debug statement

Having some trouble with the __debug extension to c++ in a console-debug
project.

When I try:

#include <iostream>
void main(int argc, char *argv[])
{
__debug int HD = 1;
__debug(HD)cout << "working" << endl;
}

There is no output. Perhaps I have misunderstood the syntax.. I thought that
"__debug (expression) statement else statement" was a conditional control ala
"(expression) ? statement : statement". Did I get it wrong?

mmmm..

I also try just:

#include <iostream>
void main(int argc, char *argv[])
{
__debug cout << "working" << endl;
}

and no output. Has the __debug extension to c++ been deprecated in DM? Perhaps I
need throw some compiler switch?

Ok, I know its an extension. I have one core module that has copious output when
debug, and it is useful to turn it on and off at times while in a debug build.

Works for me. Are you sure you are compiling with "-D"? (btw, "-DDEBUG" or
"-DDEBUG=1" doesn't work)


bye, Christof

Again? I think I'm getting a complex.. Ok, I'm using the IDE.. what switch do I
need to use to get it to add -D to the sc build? And isn't -D just a notice for
defines??

btw, the IDE has some real problems handling .def .mak .prj and .opn files. If I
try and get clever with saving .opn files to match particular builds, something
about the automatic parse causes the .def file to overwrite my defines line in
settings. Eventually, I can get things screwed up enough to require delete of
def and .mak. And sometimes even delete of the .prj file and start from
scratch.

But, I suppose it works for you.. sigh.

Sorry. I'll add that to the bug list for the IDDE.

There was a trick with the "Defines" area in the IDDE...

Yes, you can work around it that way, but it's a kludge.
