Libbsd Undefined References When Running FACE Conformance Tests

[Joel Sherrill]

Hi

Jeff has been setting up the FACE Conformance Test Suite to test
RTEMS+libbsd against the FACE General Purpose Profile. He has results for
arm/xilinx_zynq_a9_qemu which fail for 37 symbols that should be satisfied
from libbsd.


=========================
#include <net/if.h>

int main()
{
struct if_nameindex ** var0 = {0};
if_freenameindex(*var0);
return 0;
}
  =========================

The Conformance Test Suite is setup to compile the above file and then link
it. This is the link line.  This error occurred 37 times.

I apologize if the copy and paste is wonky. The report is in PDF.

Checking the source code, the line number looks like the code is different
from the master than 5-freebsd-12. It also looks like Jeff is testing
against the master. This leads to a few simple questions:

+ Should Jeff be testing using the 5-freebsd-12 branch?

+ Why isn't the master in sync enough to pass this simple test?

+ What's the relationship between the master and 5-freebsd-12?
