Are there only 32-bit OCI on Sun/Solaris?

I'm building a C application on SUN Solaris 2.7 (64bit) using OCI. In the Oracle make file to include in my make file for OCI libraries linking, I can see that the parameter xarch of SUN C compiler is set to "v7" which is the 32-bit instruction set supported by Solaris 2.7 for backward compatibility.
Setting it to "v9" (64-bit architecture) in my makefile I get errors using OCI functions, setting it to the same value in Oracle makefile I get compilation errors.

Does anybody know if there is a solution to my problem? (maybe 64bit version OCI? different paramenters in makefiles?)

Tahnks in advance
