I'm having an issue with MAX6675 Thermocouple code I am using the same code given in the cookbook with the max6675 library, but it's giving me 2 errors when I compile it...

" Undefined symbol max6675::read_temp() (referred from main.cpp.cpp.LPC1768.o). (EL6218E)" in file "/"

" Undefined symbol max6675::max6675(mbed::SPI&, PinName) (referred from main.cpp.cpp.LPC1768.o). (EL6218E)" in file "/"

here is the code from the cookbook:

Here is the max6675 library:

What am I doing wrong?
