Collect2.exe: error: ld returned 1 exit status : cannot find how to solve it

Hi All
I have been chasing my tail all day with this error. I have fixed a few of the variables defintions thanks to all the suggestins above and looked at “A new PlatformIO user coding wrong, getting multiple definition & first defined here errors - #2 by maxgerhardt.”

Here is my error:

Linking .pio\build\portenta_h7_m7\firmware.elf
.pio\build\portenta_h7_m7\src\main.cpp.o:(.bss.Breakout+0x0): multiple definition of `Breakout'

“multiple definition of `Breakout’” Breakout is from <Arduino_PortentaBreakout.h>

Here is my structure

here is my “BuckosLib_PH7_v001.h”
