When following the instructions supplied in the repository, I am getting numerous errors relating to cgo compilation. I've tried removing individual CFLAGs, yielding the same result each time. This leads me to believe that CFLAGs either do not gag their corresponding warnings or that they are being ignored in compilation altogether.
Past the warnings, I'm getting multiple build errors related to undefined references.
