https://github.com/ceph/ceph/pull/24538 was merged only a couple of months ago so I suspect this has never run successfully in luminous? I'm investigating the actual problem behind it.

Frustratingly difficult to track down...

As suspected "make" in the examples/librados directory has not worked for the duration of luminous, at least with some compilers. The problem is link order.

This fails.

$ g++ -std=c++17 -Wall -Wextra -Werror -g   -lrados -o hello_world_cpp hello_world.cc

This succeeds.

$ g++ -std=c++17 -Wall -Wextra -Werror -g  -o hello_world_cpp hello_world.cc -lrados

Basically, the libraries need to come last due to the way the linker (ld) works.

This was fixed early in the mimic cycle by https://github.com/ceph/ceph/commit/5b027155b41d15c9e9e26b81340a76673f483890 and this backports cleanly to luminous. Just testing it now and will have a PR shortly.
