[SOLVED] IAR compilation failure, CCS compilation works. Types Incompatibility

[yolco]

After developing a new firmware (main and libraries) with CCS for my CC2538, all errors are debugged, and now, device is working fine.

As from CCS I can not flash the firmware permanently, I'm working with IAR to develop this action.

On IAR, I have created the workspace, the project and included all libraries and files needed to compile the firmware. But, compilation fails due to incompatible types errors.

• Error[Pe144]: a value of type "int" cannot be used to initialize an entity of type "signed short *"

int16_t *accData[3] = malloc(sizeof(int16_t));​

• Error[Pe513]: a value of type "int" cannot be assigned to an entity of type "signed short *"

int16_t *accData[3] = malloc(sizeof(int16_t));​

• Error[Pe120]: return value type ("signed short **") does not match the function type ("signed short*")

int16_t * lsm303d_readAccData(void)
{

int16_t *accData[3] = malloc(sizeof(int16_t));
...
return accData;​

}​

Which is the root cause of these errors?
Maybe, any option of the compiler? Do I need to add any file? Or prototype on the code?

KR!

At second error the code is wrong. I missmatch at copy time.
Please find here the code for Pe513:
uint8_t xlo;
...
accData[i++] = (xlo | (xhi << 8));

None of the three code lines seems to show valid C code. The error messages are well understandable, the curious point is how CCS C could accept the code. Perhaps a code example that compiles in CCS C can clarify this.

Maybe I was a bit confusing at description. The code compiles well at CCS, the problem is at IAR.
Although I share your opinion about how CCS is accepting that code is incomprenhensible.

I have fixed the errors changing the way I reserve allocated memory with malloc.

• Original code:

int16_t *accData[3] = malloc(sizeof(int16_t));​

• Modified code:

int16_t *accData = malloc(sizeof(int16_t) * 3);​

Now, IAR compiles well, I need to develop another actions, and then I will test it on target.
