C/C++ • Github Unified_LCD woes

Hi,

When I picked up a 16x2 RGB LCD clone of the Adafruit board, the supplier suggested I utilize Dougie Lawson's Unified_LCD at https://github.com/DougieLawson/Raspber ... nified_LCD to talk to it.

Got the git cloning done, as well as:
sudo apt-get install libi2c-dev - The install completed.

cmake . - The cmake . mentioned that the checks for working compilers was skipped.

make - The make stumbled with 2 errors on the first attempt, and with similar results on the second pass (which follows):

jason@raspberrypi:~/git_files/RaspberryPi/Unified_LCD S make

Don't know if this repo is the best option or not, and issues like these are new to me. I'm hoping Dougie Lawson can touch base and point me in the right direction ...

Thanks.
