如何将oracle oci库添加到C ++ Eclipse

Question

I'm writing a method for Oracle in C++. I'm using the OCI library with Eclipse as my IDE. The code compiled completely but I'm getting this runtime error:

"error while loading shared libraries: libocci.so.11.1: cannot open shared object file: No such file or directory "

I included occi and clntsh and nnz11 through properties > c/c++ general /Path and symbols > libraries

I don't know how to fix this error, please help thanks you

Answer 1

IDE wont take like libocci.so.11.1 you have to convert into like libocci.so

ln -s libocci.so.11.1

then it will be renamed to libocci.so

then compile the code

Answer 2

Your compiler finds the libraries because your project probably specifies where to look for libs (-L flag on the linker command line). But the runtime linker needs to find the libs as well.

I assume you're running it on linux. You have 2 options:

1. A temporary solution is to define in your environment LD_LIBRARY_PATH= full path to dir where libocci.so* is installed . I'm not very familiar with eclipse, but there's likely a setting to change the runtime environment. You could also set LD_LIBRARY_PATH and then run ecplise in that env.

   $ export LD_LIBRARY_PATH=...

   $ command to run eclipse

2. A permanent solution is to add the full path to the dir. where the libs are to the file /etc/ld.so.conf, or better: create a file /etc/ld.so.conf.d/oracle and put the path in that file, nothing else. Then, as root, run ldconfig.

wow . finally i did it , by one variable and put it into .bashrc

1- export LD_LIBRARY_PATH=/opt/oracle/instantclient "The Path of libraries" and then 2- root@user:~# vi .bashrc "Make sure you are in root" 3- LD_LIBRARY_PATH=/opt/oracle/instantclient/ "Add this two lines into file" export LD_LIBRARY_PATH
