Microcontroller C project will not build in MPLAB X IDE. Do you know why?

[treez]

Hello,
We are using PIC18F26K20 and using XC8 C and MPLAB X IDE.

Our remote software guy told us he had updated the main.c file and sent it to us. When we used it to replace his old main.c file in the project, we found that the project would not build. We asked him about it, but he told us it would build and sent us what he said was the hex file from it.
Why can we not build it?

The error message is as below……….

You don't need to quote the full build log to refer to a short error message

dali_cg_nvmemory.c:369: error: (2026) variables qualified "eeprom" are not supported for this device
main.c:259: error: (1098) conflicting declarations for variable "_init_EEPROM" (dali_cg_nvmemory.c:303)

Suggestion: Scan the log for the first "error:" line, fix the error, retry.

I doubt generally that posting error messages without related code is useful at all. But in this case, the error message sounds almost self-explanatory,

Thanks

conflicting declarations for variable "_init_EEPROM"

...yes indeed we saw this line, and we suspected that there must be a variable in the code called "_init_EEPROM"..and we suspected that it had been declared somewhere as say a unsigned_int, but perhaps elsewhere as a signed_int, or whatever...however, we could not find the variable anywhere in the code......and the search feature only helps you to find something in the code file that you have open ....it wont search through all files in the project, and there are some 15 code files in this project.

 

[FvM]

and the search feature only helps you to find something in the code file that you have open

With reasonable setup, MPLAB search function covers all project files. 15 code files is a rather small project.

Without the code, I don't know if the problem is simple or not. Just wanted to point out that MPLAB tells you exactly where it sees an error. Just need to read the message.

I understand that you have just started to work with the Microchip tool chain. Expect a learning curve.
