I have a big and frustrating problem, I have a PIC18F1320, a JDM programmer, MPLAB, and this code from Junebug

But I don't konow how to compile it into a hex file that I can write with icprog
Code:
#include <p18f1320.h>
#pragma config WDT = OFF, LVP = OFF, OSC = INTIO2
#define ServoPin LATBbits.LATB3
#define ServoTris TRISBbits.TRISB3

void main(void){
int ServoPos;
    OSCCON=0x70;                //Osc=8MHz
    ADCON0=0b00000101;          //A2D on and select AN1
    ADCON1=0x7d;                //A1 = analogue
    ADCON2=0b10110101;          //Right justify - Fosc/16
    ServoTris=0;                //make servo pin output
    ServoPin=0;                 //Servo output off
    CCP1CON=0b00001011;         //Special event trigger
    T1CON=0b10010001;           //Timer 1 on with Pre=2
    ServoPos=1500;              //set servo to mid position
    CCPR1=ServoPos;             //set CCP initial value   
    while(1){
        while(!PIR1bits.CCP1IF);    //wait for CCP interrupt bit
        ServoPin=0;                 //end pulse
        CCPR1=20000-ServoPos;       //Off time = 20mS - Servo Time
        PIR1bits.CCP1IF=0;          //clear int flag
        ADCON0bits.GO=1;            //start conversion
        while(ADCON0bits.GO);       //Wait for it to complete
        ServoPos=ADRES+1000;        //Pos will be 1mS to 2.023mS
        while(!PIR1bits.CCP1IF);    //wait for int flag
        ServoPin=1;                 //start pulse
        CCPR1=ServoPos;             //Servo time in uS
        PIR1bits.CCP1IF=0;          //clear int flag
    }
}

Looks like my Junebug servo code.

Start a project in MPLAB with the project wizard.
Select 18F1320 and C18.
Add a file called somert.c to the project and copy the above code into it.
Press F10.

Edit, you add the file after the project wizard has completed. Look under menu Project->Add new file.

HTH,

Mike.

I didn't find anywhere somert.c so i created a file with that name. When I pres F10 this error shows

Try downloading and installing the latest version of C18. Your paths are not setup correctly and installing the latest version should fix that.

I installed all the programs three time and it is the same
What does it mean that

somert.o is out of date.
