[flashrom] ./flash command not found?

Hello!

I am attempting to install libreboot onto an old macbook while following a guide. I am having an issue where the ./flash command is giving me an error in terminal saying that it is not a valid command. Other commands I give to flashrom work fine, but ./flash does nothing.

The command I am attempting to run is "sudo ./flash i945apple_firstflash 'path_to_my_rom_file'" and get back "sudo: ./flash: command not found"

I am very new to linux so I'm probably missing something but any help would be greatly appreciated.

Thanks!
