xTaskCreate()/xTaskGenericCreate() are base functions that are always included no matter what the configuration of the system - so the only thing that comes to mind is that you are not building the source file that contains the function’s definition. Are you building FreeRTOS/Source/tasks.c?
In any case, FreeRTOS comes with example pre-configured projects for every official port specifically so people don’t have to work out how to build themselves, but can instead start with something that is already building, then modify that for their own purposes. Obviously we can’t cover every possible combination of everything, but imagine you will be able to find a pre-configured project that is at least close to what you need.
Did you read the quick start guide?
