out of ROM , 16F877 ....

[beetS]

I have the compilation error , error 71 out of rom as said in the topic.

The problem is that when i use the same program, the same ICD module, and the same card with the same pic at school, this error doesnt appear.
My question is : why when i try to compile the program at home have i this error?

I took the CCS config file, from my school post and the error still...

Post your preprocessor lines, i.e. all lines beginning with #, that you are using.

Hello,

I have the same problem of error 71 "out of rom segment : MAIN".

I have a main sub (24% of memory on my 16F877A : 8192b) and an interrupt sub routine (app 5% of ROM).

When I insert a call to a function in the interrupt sub (#INT_RB), the error appears. If I put this function into the main, the error does not appear anymore. If I add more functions, delays or others in the main loop, no memory problem, even in excess of 2k !!!

I need to run a program in the interrupts, so I which I will understand...

If you have ideas, I'm your man !
Thanks

Post a small compilable code that demonstrates the problem (with all preprocessor directives).

Do you use #ORG instructions?
What is your compiler version?

No, I don't use #ORG.

My compiler version is V4.057.
My MpLab version is 8.01 (using IDE for my ICD2).
My OS is Win XP SP2.
My age is 29 (maybe not the most important).

I tried to compact my code, but the error disapears...(my code is not very "compact" : about 2k of ROM, and it needs some files and libraries).

I develop a trigger with a delayed output (interrupt on an input, output on a pin and on another with a delay from 0.1 to 5000ms. The delay is adjustable by the user via 3 push-buttons and a 2x16 LCD.

In the main : the init, splash screen, and that's all.
In the interrupt routine, the delay, and I wish, a screen with the system state.
The problem is that when I introduced a function like lcd_gotoxy(x,y) in this interrupt routine, the compiler say me the code is out of space.
I can place this function in the main, and have no problem.

[Matro]

Try to add "#separate" just before the declaration of the function "lcd_gotoxy()"

[Fred8]

Same result...

May it be a problem of memory allocation (stack / heap)?
A compiler issue?

See this post about re-arranging your code to fit in a PIC:

You can eventually copy-paste here the .err file.

OK, many thanks for the command line, the solution was here !
