I am unable to build this in MPLAB X. I cannot figure out what is wrong with it.

    list        p=12F509

No hint as to what the error is? What does the compiler say?

 

I get this message
Error - could not find definition of symbol 'delay10_R' in file './test.o'.
Also are you compiling in relative or absolute?
Max.

 

Can you do a print screen of the error message window? If you double click on the error message it might take you to the line of code with the problem.

 

The code is from the Gooligum Baseline lesson three.

BUILD FAILED (exit value 2, total time: 2s)

 

That is the same as I posted, it seems your external reference to delay10_R is missing or in error?
Max.

 

Max...I have no idea what compiling in relative or absolute is. How can I find out how I am compiling?

 

There is usually a question at the first build time, but you can change at any time from the Build Options/Project/MPASM
Max.

 

Did you do the lesson step by step and take note about including relocatable code?
Such as the Delay10.asm included in the source files etc.
Max.

 

If you are intending to compile code to insert into a PIC then you want an absolute build.

A relative build is for times you are creating a library function that needs to be relocatable to an arbitrary address (AFAIK).

I believe MPLAB will bark at you if you try to program with a relative build and suggest the proper alternative.

 

Have you edited the Delay10 file to include the GLOBAL directive?
And do you have it in your source files, or alternatively the .o version in the Object file list?
Max.
