It is difficult to say without seeing the actual error, but it sounds
like your error is unrelated to loadable modules. There is something
wrong with your #include statements and/or with your -I options.

Copy-pasting compiler error message(s) may be a good start to get that
problem resolved. Please note that if you cannot compile your module
without special linking options, then your problem is most likely
unrelated to the loadable modules API (or Polygraph). It is most likely
just a basic C++ development bug.

That command does not match the command in the Reference Manual. That
mismatch does not mean that your command is wrong, but please explain
why you removed the arguments after "-Wl,".

The published instructions appear to be quite detailed to me, although I
do not know of anybody using loadable modules with Polygraph for a few
years. I am not aware of any other instructions.

If it is not a secret, what will your module do?

Thank you,
