I know I just asked a similar question a few hours ago, but I feel like throwing my computer across the room right now in anger!
*one...two...three*
phew
Okay, MinGW is NOT giving me the proper information on this linker error.
I really hope it isn't something trivial, because I have been working on it
for the past hour to no avail.
The file I THINK it's happening in is this one:
////////////////////////////////////////////////////////////////////////////////
//instruction is an abstract base class. In order to create instructions, you inherit from
//this abstract base. std::string name is what you have to type in order to access
//this instruction, so if name = "Print", then inside the script you would have to
//type Print.
////////////////////////////////////////////////////////////////////////////////
//In order to use: add argument variables like so: Variable<whatever> argument1, etc....
//as arguments to the overloaded Execute function.
//type is where the instruction is used, like: World Map, or Battle, etc....
//redefine name for. After all of this they should overload Execute with whatever
//they need it to do, and how they want it to interpret arguments.
////////////////////////////////////////////////////////////////////////////////

namespace aeroscript
{
class Instruction //virtual base
{
protected:
std::string name;
//this isn't important, just something like BATTLE or ACTION
std::string type;
public:
friend class InstructionList;
//sets up the name, type, and uses InstructionList::Add(this)
virtual void Initialize(){};
virtual void Execute(){};
};
//this class holds a list of all the instructions for easy parsing by the script
//the only reason this is in the same file is that if it's not, I become buffetted
//with linker errors from hell.
//screw you MinGW.
class InstructionList_
{
std::vector<Instruction*> instructions;
public:
void Add(Instruction* instr_)
{
instructions.push_back(instr_);
}
}InstructionList;
}
#endif
This is the error:
