Getting error while linking an OCCI program on AIX

Question

Hi All , I have written one sample program for connecting Oracle in C++ using OCCI..

It is giving me a runtime error .

ld: 0711-317 ERROR: Undefined symbol: .oracle::occi::Environment::createEnvironment(oracle::occi::Environment::Mode,void*,void*(*)(void*,unsigned long),void*(*)(void*,void*,unsigned long),void(*)(void*,void*))
ld: 0711-317 ERROR: Undefined symbol: .oracle::occi::Environment::terminateEnvironment(oracle::occi::Environment*)

I have given the following command to execute it

g++ -o occi amrtest.cpp -Wall -I/oradata/oracle/product/10.2.0/db_1/rdbms/public -L/oradata/oracle/product/10.2.0/db_1/lib -lclntsh  -lnnz10 -locci -lclntsh  -lnnz10 -locci10

Can u help me in getting this error resolved ?

I am not an AIX nor Oracle expert, but seems that your LD_LIBRARY_PATH (or equivalent in AIX) should include $ORACLE_HOME/lib. Check this forum entries:

Hey thanks for your feedback , I checked my Oracle lib file , That file was missing the definitions for the createEnvironment and TerminateEnvironment. So i downloaded the latest lib from Oracle site and then it worked properly :)
