invalid interrupt vector names for device

Hi guys,

I keep getting the following warning when compiling my program. It is:
serial.c:355: warning: Invalid interrupt vector names for device '24FJ128GA106' are:
U4

The PIC24F128GA106 series has 4 Uarts. I'm not sure why I am getting that error.

My ISRS look like the following:

void __attribute__((interrupt, auto_psv)) _U4RXInterrupt(void)
{
...
}

Any help would be appreciated

The interrupt vector names are defined in the linker script file.
Have a look at it to see if the name exsists.
Ignore the extra underscore stuck in the front of the names in the linker file.
