I have a simple test program that when I run I get:
./hello: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or d
I had to do the following (in Kubuntu 16.04.3):
sudo apt-get install libaio1 libaio-dev
sudo find / -iname 'libaio.a' -type f
--> resulted in /usr/lib/x86_64-linux-gnu/libaio.a
export LD_LIBRARY_PATH="/usr/lib/oracle/12.2/client64/lib:/usr/lib/x86_64-linux-gnu"
