I could use some help with the C30 compiler/linker.
The compile process works just fine producing .o files.
The linking process fails.


The compiler error:

Executing: "C:\Program Files\Microchip\MPLAB C30\bin\pic30-gcc.exe"
-Wl,"C:\NP\NeuroLogica\Analog\Software\ISRs.o","C:\NP\NeuroLogica\Analog\Sof
tware\HEX.o","C:\NP\NeuroLogica\Analog\Software\Inits.o",-L"C:\Program
Files\Microchip\MPLAB C30\lib",--script="C:\Program Files\Microchip\MPLAB
C30\support\gld\p24HJ256GP206.gld",-o"Hex Analog Test.cof",-Map="Hex Analog
Test.map"
C:\NP\NeuroLogica\Analog\Software\ISRs.o(.text+0x2c): In function
`_U2RXInterrupt':
C:\NP\NeuroLogica\Analog\Software\ISRs.c:72: undefined reference to
DataRdyUART2'
C:\NP\NeuroLogica\Analog\Software\ISRs.o(.text+0x3c):C:\NP\NeuroLogica\Analo
g\Software\ISRs.c:74: undefined reference to `ReadUART2'

Relevant code:

#include <uart.h>			/* UART Functions support. */

//UART_2 Receive ISR
char UART2Buffer[80];
char * Received_data = UART2Buffer;
void __attribute__((__interrupt__)) _U2RXInterrupt(void)
	{
	IFS1bits.U2RXIF = 0; // Clear the UART2 RX IRQ Flag bit.
	while(DataRdyUART2())
		{
		( *(Received_data)++) = ReadUART2();
		}
	}

Apparently the compiler knows where the reference is, (uart.h)
but the linker doesn't?



For any help:
Ad(THANKS)vance
