Can you run:

$ g++ --print-file-name=plugin

If that prints a directory, can you check that it contains the
include/ subdirectory and a bunch of header files (.h) inside?

If this all checks out, then it's most likely GCC 8 is too new
for ODB 2.4.0 and I suggest that you try to build the latest
pre-release of ODB 2.5.0 (which is known to work with GCC 8)
by following these instructions:
