Installing ROracle in linux

I am trying to install the ROracle library in linux environment. I have R version of 3.3.3 in my machine and cannot upgrade it due to business requirements. I have followed the steps below:

Install the oracle clients:
oracle-instantclient19.6-sqlplus-19.6.0.0.0-1.i386
oracle-instantclient19.6-devel-19.6.0.0.0-1.i386
oracle-instantclient19.6-basic-19.6.0.0.0-1.i386
oracle-instantclient19.6-odbc-19.6.0.0.0-1.i386
oracle-instantclient19.6-jdbc-19.6.0.0.0-1.i386
oracle-instantclient19.6-tools-19.6.0.0.0-1.i386

This was followed by the command:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib64:/usr/lib/oracle/19.6/client/lib/ R CMD INSTALL --configure-args='--with-oci-lib=/usr/lib/oracle/19.6/client/lib/ --with-oci-inc=/usr/include/oracle/19.6/client' ROracle_1.3-1.tar.gz
After running the above command, I am getting error below:
`I am getting the below error:

    `
    I also checked the location /usr/lib/oracle/19.6/client/lib/ and the file libclntsh.so is present. It is also pointing to libclntsh.so.19.1

Can anyone provide some guidance on what I might be missing. Is the version of ROracle that I am using incompatible with oracle 19.1?

Thanks in advance for your help.
