Compile problems

[piperpilot]

Dave, I am trying to get polyclip to compile on Ubuntu so I can continue development of the DRCBOTV2. I got past a first issue of not linking to the math library but now am getting the following when I try to build the lib:

cpope@ubuntu:/var/www/drc-daemon/polyclip$ make lib
CC build/src/polymath.o
src/polymath.c: In function ‘PC_phase_two_firstpoly’:

collect2: ld returned 1 exit status
make: *** [build/libPolyClip.dylib] Error 1
cpope@ubuntu:/var/www/drc-daemon/polyclip$

Any Thoughts?

Thanks,
