Error using stdint.h types

Hi there,

I am getting the next error when I try to compile a program for a ADSP-21489:

'cc0020:  error: identifier "uint8_t" is undefined'

Code is very simple:

#include <stdint.h>

int main( void )
{
/* Begin adding your custom code here */
uint8_t u8_alex;
u8_alex = 1;
return 0;
}

stdint.h file is on the correct path ("C:\Program Files (x86)\Analog Devices\VisualDSP 5.1.2\214xx\include").

Is there a way to solve this problem?

Thanks in advance
