I'm using RedHat OS to build a C++ program that is using OCCI to connect with an Oracle DB.
I had to reinstall everything and I found that my make file is adding the header files from the following path
/usr/include/oracle/18.3/client64
Which isn't available anymore
The only installation I remember I need is installing oracle-instantclient-basic
I've downloaded the rpm and installed using the command rpm -i ***.rpm
But the folder /usr/include/oracle isn't there
Note: The path /usr/lib/oracle/18.3/client/lib is found and all libraries I use for linking are there (only header files are missed).
I could investigate and find the solution
The header files are not created by installing oracle-instantclient-basic but you should install oracle-instantclient-devel
/usr/include/oracle/18.3/client64 is the path for 64bit version and the path is /usr/include/oracle/18.3/client for 32bit versions.
All the tools can be downloaded from oracle website
