I think you right, there is something wrong in the linkage. Well, I am in the beginning of using Bison, so what I do is pretty basic. I have indeed included properly the file, because when I create an instance of my class(lets say variable.h), it throw me an error. When I only declare a pointer to the class, it recognizes it, but it throws me an error when I try to allocate memory for it.
Do you have any guide, on how to include a library to bison. I will search it by myseld, but if you got somehting, it'd be useful.
