Hello,
I build a Rocket (no verniers and RCS)and try to compile it ,but there are 4 errors show in c++. I managed to find the problems but I failed.I don't know what's wrong with my code,so I post it here and hope someone can help me find the solution. Thanks!

Here is the code:


Code: 
#define ORBITER_MODULE
#define STRICT
#include "Orbitersdk.h"

//=============================================================
//Some Parameters of the Rocket
//=============================================================
const double MAX_MAIN_FUEL = 1.6e3;
const double MAX_MAIN_Thrust = 5.4e4;
const double VAC_MAIN_ISP = 5400;
const double NML_MAIN_ISP = 4500;
const double P_NML = 101.4e3;
//=============================================================
class Rocket: public VESSEL2 {
public:
    Rocket (OBJHANDLE hObj, int fmodel): VESSEL2 (hObj, fmodel) {}
    ~Rocket () {} 
        PROPELLANT_HANDLE ph_main;
        THRUSTER_HANDLE th_main;
        void Rocket::clbkSetClassCaps (FILEHANDLE cfg)
        {
        SetSize (23.0);
        SetEmptyMass (2000);
        SetCrossSections (_V(179.19,12.02,179.06));
        SetPMI (_V(632.84,1.74,632.85));
        AddMesh ("test_rocket");
        ph_main = CreatePropellantResource (MAX_MAIN_FUEL);
        th_main = CreateThruster (_V(0,2.2,0), _V(0,3,0), MAX_MAIN_Thrust, ph_main ,VAC_MAIN_ISP, NML_MAIN_ISP, P_NML);
        AddExhaust (th_main, 18, 3);
        }
}
//=============================================================

DLLCLBK VESSEL *ovcInit (OBJHANDLE hvessel, int flightmodel)
{
    return new Rocket (hvessel, flightmodel);
}
DLLCLBK void ovcExit (VESSEL *vessel)
{
    if (vessel) delete (Rocket*)vessel;
}

You need a semicolon after the closing brace in your class definition. :)

i.e.,
Code: 
class Rocket: public VESSEL2 {
...snip...
}[COLOR="Red"];[/COLOR]

Thanks for your help,I have add the semicolon.But there is a problem disturbing me.The c++ show 38 errors,the error is error LNK2001:Unresolved external symbol. This error looks very strange! How can I do? Thanks!

Please make sure you are linking with the Orbiter libraries (orbiter.lib and Orbitersdk.lib). A good place to start from a template project standpoint is to look at a sample Orbiter C++ project such as Orbitersdk\samples\ShuttlePB\ShuttlePB.sln.

Yes ,you're right! I only add the lib path but forget adding orbiter.lib and Orbitersdk.lib .
Now I compile it sucessfully! Thanks very much!
