The simplest to get to work is the static library version. Be sure to
exclude dll.cpp from the project then. (Not sure if it will be a
problem when not building a DLL, I'm no MSVC expert)

No clue about these. Probably MSVC needs some new syntactic sugar for
precompiled headers.

Good.

Or some objects are included twice or maybe you're using different
compile settings for the library and the project linking to it? Does
it work if you just make one big project with the antlr files and the
files from the sample?

I'm not sure which MSVC version you're exactly using if it's newer
then version 7.1 it may need some tweaking in the config.hpp. Looking
at the error you might have to tinker with the define that tells how
constants should be declared.

There have been some posts in the past to the mailing list. But these
have been mostly merged into the readme of the runtime (in lib/cpp)
When I get some time, or when someone else feels like it, it would be
nice to add a wiki page on it.

It seems Wolfgang didn't have time to make nice release packages for
the last version at least he did for 2.7.6 (or was it 2.7.5?).
Although with the C++ version one often has to recompile anyway for
specific compiler settings etc. Myself I never figured out how to make
a complete package with everything in it for windows. So usually if no
one contributes binaries they won't get made.
