Hi David,

thanks for the support, read below.

I also cheked - there is no other libobjc on the system, no libobjc2 
package installed from ports.

freebsd 12.1 system compiler is clang 8.0.1
I added these options because they are mentioned like this in your 
INSTALL file!

Just as a test, I did again a  clean build with absolutely no options, just:
cd Build
$ cmake ..

make -j2

<.... build...>

-> all 178 tests fail.

where are the errors of the tests?
