Failed to generate binary outputs when generating code for c2000 processor using s function builder block and simstruct.h

Am getting these errors

The code wrapper was generated automatically by the s-function builder block, and works fine in normal mode, when generating the code to run in external mode it returns these errors. This is the code.

71    void ssfuntest_Update_wrapper(const real_T *V,
72			real_T *Vc,
73			real_T *dVc,
74			real_T *xD,
75			const real_T *R, const int_T p_width0,
76			const real_T *L, const int_T p_width1,
77			const real_T *C, const int_T p_width2,
78			const real_T *I0, const int_T p_width3,
79			const real_T *Vc0, const int_T p_width4,
80			const int_T y_width,
81			const int_T u_width,
82			SimStruct *S)
83    {
84    /* %%%-SFUNWIZ_wrapper_Update_Changes_BEGIN --- EDIT HERE TO _END */
85    real_T tempX[2] = {0.0, 0.0};
86    real_T A[2][2]= {{0,1},{-1/(C[0]*L[0]),-R[0]/L[0]}};;
87    real_T B[2]={0,1/(C[0]*L[0])};
88    long double t = ssGetSampleTime(S, 0);
89
90    tempX[0]=(A[0][0]*xD[0]+A[0][1]*xD[1]+B[0]*V[0])*t;
91    tempX[1]=(A[1][0]*xD[0]+A[1][1]*xD[1]+B[1]*V[0])*t;
92    xD[0]=xD[0]+tempX[0];
93    xD[1]=xD[1]+tempX[1];
94    /* %%%-SFUNWIZ_wrapper_Update_Changes_END --- EDIT HERE TO _BEGIN */
95    }

I can't seem to find what's worng with it. I find it strange to have all the erros in the update method. This is a simple RLC circuit dynamic response function for test purposes.

Thank you in advance for any help.
