LCT (Legacy Code Tool) MEX compilation error in using TI C2000 related C code compilation

I am using Matlab2016a and MinGW 4.9.2 compiler (in Windows8.1). And, using LCT (Legacy Code Tool) to generate an Oscillator Compensation sfunction related to TI-C2000 processor. Below are the code

---------------- freqcomp.h ----------------------
#ifndef _FREQCOMP_H_
#define _FREQCOMP_H_
#include "tmwtypes.h"
void freqcomp (unsigned int u1, unsigned int y1);
#endif
---------------- freqcomp.c ----------------------
#include "freqcomp.h"
#include "DSP28x_Project.h"
#define getOsc1CoarseTrim() (*(int (*)(void))0x3D7E96)()
void freqcomp (unsigned int u1, unsigned int y1)
{
  int compOscFineTrim;
  EALLOW;
  compOscFineTrim = 13;
  SysCtrlRegs.INTOSC1TRIM.all = GetOscTrimValue(getOsc1CoarseTrim(), compOscFineTrim);
  EDIS;
}

Please help me getting these mex compilation errors resolved. The unique errors are:-

I have used following lct commands:

def = legacy_code('initialize');

def.SFunctionName = 'sfunc_freqcomp';

def.SourceFiles = {'freqcomp.c'};

def.HeaderFiles = {'freqcomp.h'};

def.OutputFcnSpec = 'void freqcomp(uint16 u1, uint16 y1)';

def.SrcPaths = {'C:\ti\controlSUITE\device_support\f2802x\v127\DSP2802x_common\source' , 'C:\ti\controlSUITE\device_support\f2802x\v127\DSP2802x_headers\source'}

def.IncPaths = {'C:\ti\controlSUITE\device_support\f2802x\v127\DSP2802x_common\include\' , 'C:\ti\controlSUITE\device_support\f2802x\v127\DSP2802x_headers\include\', 'C:\ti\controlSUITE\development_kits\~SupportFiles\F2802x_headers'}

def.LibPaths = {'C:\ti\controlSUITE\device_support\f2802x\v127\DSP2802x_common\lib'}

legacy_code('sfcn_cmex_generate', def);

legacy_code('compile', def);

I have the same problem with the includes of a c2000 processor in the S-Function Builder.

Hi!

`cregister` and `interrupt` are C extension keywords defined by TI, so they cannot be recognized by common compiler (MinGW in your case). I think this is the problem that causes these Compilation Errors.
