IIRC: The "standard C" way to do this is:
In one, and only one, .cc file, do at the top level (not in any class,
method, or function definition), e.g.:
int foo = 0;
then in the .h file do:
extern int foo;
and you should be able to access 'foo' from any code the includes
that .h file.

I'm looking for suggestions on how to implement a variable that is
shared between two blocks.
If I include the same header into the .cc files implementing my blocks
I get the "multiple definition of variable x" error.
Which is the correct way to do this?
is there an example available?
