Without more information, it sounds like you're trying to link to yy_globals.
However, yy_globals is not a global symbol. (Yes, it is poorly named. We'll
rename it ASAP!) It is a local variable of type (void*) in the yylex()
function. You need to pass it to any flex functions, e.g.,
yy_push_state(IN_COMMENT,yy_globals);
