void UART0Interrupt (void) __irq //Read from UART0
{
unsigned char temp_U0RBR;

if(U0LSR & 0x01) //RDA Int Enable
{
flg_Rxd0_Receive = 1;

temp_U0RBR = U0RBR; //Reset RDA Int
if(temp_U0RBR)
{
flg_Rxd0_Receive = 1;
}

#if MODBUS_DEVICE_CONFIG == MODBUS_MASTER
ModBusResponseReceive(temp_U0RBR);
#else
ModBusQueryReceive(temp_U0RBR);
#endif
}

VICVectAddr = 0;

}

i didnt get isr properly it throws an error.

Gosh. You did something; don't bother saying what; got an error; give no clue what it might be; and still want answers?

What is throwing the error?
What is the error?

Is it in your title: "Type expected '=', ',', ';', 'asm' or '__attribute__' before '__irq"?

Are we to assume interrupts.c is the actual code you are using? If so, I noticed you commented out "__irq". Why was it there in the first place? Whose code is it? What's it for? GCC doesn't know what it means. Maybe you want another compiler (like for ARM)?

A little more information is needed like

We shouldn't have to guess.

Let's guess anyway:

- The target is an ARM7TDMI cross-compile for LPC213x,
- The code tries to be an UART driver for MODBUS.

- There is something fishy with the included headers,
preventing the compiler to recognize the __irq macro,
or this is a port from e.g. 8051 code, and the interrupt
handler has to be configured differently.

It would help guessing if:
- The host operating system were told,
- The cross-compiler make and version were told,
- The compilation switches were told.
