In my program I need to verify prints with images, and the fp_internal.h 

"int fpi_img_to_print_data(struct fp_img_dev *imgdev, struct fp_img *img, 
struct fp_print_data **ret)"
"fp_img *fpi_img_new(size_t size)"
would be extremely useful, but as I try to use them I receive the error message:
symbol lookup error: 
undefined symbol: fpi_img_to_print_data
I'm using JNI to bridge libfprint to my java application
Thanks in advance
