I am having trouble linking BSEC3-3-0-0 (libalgobsec.a) the problem seems to be a function bsec_get_instance_size() which is missing from the library .a. This function is missing from all three of the Arm Archicture library .a files. The function bsec_get_instance_size(void) is present in bsec_interface.h and there is nothing in the release note to say this has been removed.
I checked the BSEC3-2-1-0 release and bsec_get_instance_size is present in the RaspberryPI libalgobsec.a files. I used the nm utility to list the symbols from the library.
Thanks
