Is it possible to build the rapid accelerator target without running it

I'm trying to diagnose why my simulink model won't build in rapid accelerator mode, and I'm stepping through the code sequentially uncommenting out code and clicking run to build the rapid accelerator. When it does build successfully, MATLAB crashes when trying to run the code.

If your code doesn't builds in rapid accelerator mode then your model may have blocks that represent hardware.

Please share your code and paste the crash dump so that we can see what is causing the crash when you run your code.

You can refer to the following sites for info regarding rapid acceleration in Simulink :

I can't share the code but I can provide some of the crash:

Sim_data.c(18405) : error C2099: initializer is not a constant

Sim_data.c(18406) : error C2078: too many initializers

NMAKE : fatal error U1077: '"C:\...\win32\Microsoft Visual Studio 2010\VC\Bin\amd64\cl.EXE"' : return code '0x2'

Stop.

The make command returned an error of 2

'An_error_occurred_during_the_call_to_make' is not recognized as an internal or external command, operable program or batch file.

Sim_data.c(18405) : error C2099: initializer is not a constant

This can occur due to two reason :

• A function in your code needs to be declared and visible before being used. Function prototypes are recommended, but not strictly required. But visibility to a function definition is required before it is used anywhere. If you are using any functions in your code as a struct member create it's prototype before using it. You can create the prototype in a separate header file.

protocol.h

typedef struct
{
    char name[24];
    signed int (*Send)(char*, int);
} S_DEVICE;

//prototype here
static signed int myfunc(char* buf, int len);

device.c

#include "protcol.h"

S_DEVICE var = {"ten", myfunc}; 

int main(void)
{
   return 0;
}

//define here
static signed int myfunc(char* buf, int len)
{
    return 0;
}

• If you are using C and declaring a constant in your code using

const

then you can try using

#define

The constant you are using may be a "large" object and in C language it is not a constant expression, even if it is declared as const. In C language the term "constant" refers to literal constants (like 1, 'a', 0xFF and so on), enum members etc. This works with C++ though but if its a large object better use #define even in C++.

For example, this is NOT a constant

const int N = 5; /* `N` is not a constant in C */

The above N would be a constant in C++, but it is not a constant in C.

Sim_data.c(18406) : error C2078: too many initializers

This occurs when the number of initializers exceeds the number of objects to be initialized. Somewhere in your code you might be declaring more objects than allowed. Something of this type :

int main() {  
   int d[2] = {1, 2, 3};   // C2078  
   int e[2] = {1, 2};      // OK  

     char a[] = {"a", "b"};  // C2078  
     char c[] = {'a', 'b'};  // OK  
  }

NMAKE : fatal error U1077: '"C:\...\win32\Microsoft Visual Studio 2010\VC\Bin\amd64\cl.EXE"' : return code '0x2'

You may be using the MSVC2010 for 64 bit version instead of 32 when you are building. Try reinstalling Visual Studio with the correct version.
