Hi I'd like to try ccv out, however its been a while since i've compiled C stuff, I apologize for what is probably a ccv-agnostic gcc question. From the tutorial at http://libccv.org/tutorial I downloaded the c code for face recognition and saved as face.c in the /lib directory. Then from the lib directory I tried $gcc face.c -I . -L .
(and also without the -L. ) but run into several errors such as 'undefined reference to ccv_read_impl'

after ./configure && make in /lib I also tried clang -L. -I. face.c -lccv cat .deps which produces an a.out that segfaults - tho it seems the make was not entirely happy , it seems to be expecting a git repository...

Seems this should help:

extern "C" {
#include "ccv.h"
}
