I had a similar error when trying to install ROracle from source.1

Updated the following Environmental Varibles in windows
SET PATH=C:\Rtools\bin;C:\Rtools\gcc-4.6.3;%PATH% SET OCI_INC=C:\Oracle_11G_ClientR2\product\11.2.0\client_1\oci\include SET OCI_LIB32=C:\Oracle_11G_ClientR2\product\11.2.0\client_1\BIN SET OCI_LIB64=C:\Oracle_11G_ClientR2\product\11.2.0\client_1\BIN R CMD INSTALL --build "C:\temp\ROracle_1.1-12.tar.gz"
Output should look like the following:
