I just successfully compiled it for a Nano. When I see a line in your message that says:

sketch_apr04a:24:9: error: 'uint8_t index' redeclared as different kind of symbol

This tells me that something is wrong in your environment. You should have a folder called:

inoise8_fire and that the ONLY file in that directory should be inoise8_fire.ino

Also, this is what the file should look like (lines 1 through 78):
