Re: Bison complains about undefined reference of my own data type

[Vukki Starborn]

What exactly say the compiler?
If you get some undefined reference message on stage of compilation of bison
output, then you must check if all needed definitions really included.
If you get undefined reference message on linking stage, the solution
usually is to add object file with implementation to project.
Also there may be troubles at linking stage if different parts of your code
compiled with different linkage (C vs C++). C++ compiler use demangling
while C not.
As i can see, the problem not in bison, but in proper way to link all of
your code together.
