^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It seems you do not set ORACLE_HOME env variable. Hence, it can't find
oci.h. Check Makefile for details.

There is something wrong with your env. Do you have CC set? What is
your pg_config output?

 Euler> There is something wrong with your env. Do you have CC set? What

This is what you get if you try and compile extensions against a server
built with --with-llvm, on a machine that doesn't have clang installed.
I mentioned to Andres that we really ought to have an official way to
disable the LLVM bitcode build for such cases, but right now there isn't
one. "with_llvm=no" on the make command line is worth a try, but I
wouldn't bet much on it working.

Otherwise, install llvm version 7 (including clang).
