There is the smoking gun.  You can't mix and match those two.

===================================

Thanks, Gary.  I don't know how the "ELF 32-bit LSB pie executable" got into 
the libgps.so, but it is from running the "scons --config=force && scons 
install" from the gitlab as you suggested.  I can tell that from the date 
and time.

Checking the cgps executable (which works):

pi@raspi-3:~ $ file `which cgps`
/usr/local/bin/cgps: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), 
dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 
3.2.0, BuildID[sha1]=9a25919cfce7994c5238a0f8171bebbe716c3019, stripped

shows that compiling as part of the scons commands produced a working 
program (without the "pie"), so I should be able to compile my program in 
the same way if you could please share the compile and link used to create 
cgps.  I don't know where to look in the git clone to see the flags and 
commands.

Thanks,
David
