DevOps, CI/CD and Automation

I installed the python DCOracle2 interface on Tru64 (DEC unix) to Oracle 8.1.6 and I keep getting an unresolved symbol for OCIEnvCreate. I used nm on the libclntsh.so file and the symbol shows up in the .so file. I wrote a c program to call OCIEnvCreate and I get the same unresolved symbol error. I tried to add the following line to the shrept.lst file
rdbms : OCIEnvCreate
and reran make in the $ORACLE_HOME/rdbms/lib directory, but this didn't seem to help.

Thanks in advance for any help
