QUESTION

Embedded C, and AVR GCC compilation issue with multiple definitions

Asked 2020-Feb-01 at 14:03

It seems that my compiler does not willing to build the firmware in stepper_motor.c and as you can see below, it throws this error, which I am unable to solve.

I have created a stepper_motor.c source where all my functions and variables are placed, and a stepper_motor.h header where all the #defines and function prototypes are. In main.c I just include the stepper_motor.h header and use the functions. As you can see from shell log data, it does not compile and tells that 4 x variables are defined multiple times. Those ones are used in ISR() routine for a timer, so they need to be also volatile.

Any information would be highly appreciated on this issue.

this is my main.c includes: --------

Really the error messages tell you all you need to know - you have defined these symbols in two places - main.c and setpper_motor.c.

You have defined stepCounter at line 50 of stepper_motor.c and also as shown in main.c. Similarly for stepPase and motor_Phases.

If they are independent and should not be visible externally then both should be declared static so that they are visible only in their respective translation units.
If it is intended that the symbol refers to the they are the same object, then one of them needs to be declared extern to indicate to the compiler its type and name, but that it is defined elsewhere..
If they are independent but "need" to be global (because you cannot think of a better solution), then they cannot have the same name.
If you do not reference them in main.c, then they should in any event be removed from there. It seems odd that you would define them here when they clearly relate to stepper motor control and should probably be encapsulated in stepper_motor.c.

Avoiding the use of globals in the fist place is a much better solution see https://www.embedded.com/a-pox-on-globals/

Run make VERBOSE=1. What linker command does it run? It must be missing -luv. To fix that, add something like this to your CMakeLists.txt:
