Compiling the OCCI application on linux

Hi,

i have the OOCI application which will connect to oracle database using OCCI.
i have added oraocci11.lib in the additional libs and working fine.
In linux i have added –locci and –lclntsh and compiling good.
it is not giving any linker errors even i remove –locci and –lclntsh these in compiler options.
please help me understanding how these libraries work in linux.
i have libclntsh.so.11.1 , libnnz11.so, libocci.so.11.1, libociei.so and libocijdbc11.so libraries.
Do we need to have any .a files to add to the additional libraries.
how does it work????
Pelase help.

Thanks,
Sreekanth Polaka

    Can you post your compile and link line.
    BTW oraocci11.lib is a Windows library and when you say you have added that in additional libs and working fine I am unable to understand.
    For an OCCI application to successfully compile and work
    - you need to pass -I$ORACLE_HOME/rdbms/public during compilation to pick the headers
    - pass -L$ORACLE_HOME/lib -locci -lclntsh during linking.
    libclntsh.so.11.1 is the client library every application connecting to server is required to link with
    libocci.so.11.1 is required if your application is an OCCI application
    libocijdbc11.so is required for JDBC applications
    libociei.so is required if you want your application to run in Instant Client Mode.

    Hi,
    My application runs on both windows and Linux.
    In the windows i add the library oraocci11.lib for the linking. if i remove the library i will receive link error.
    But in Linux i am not receiving link error even if i remove -locci -lclntsh during the link.
    I am concerned how the OCCI function calls are getting resolved in linux.
    Please help.

    Thanks,
