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

Question

I'm making a C program which is connecting a oracle DB. I have correctly installed the Oracle Instant Client and ocilib.

And I did compile the code without any error but when I executing the program I got following error.

./a.out: error while loading shared libraries: libclntsh.so.11.1: cannot open shared object file: No such file or directory

If anyone know how to solve please write it Thank you.

Answer 1

You need to setup LD_LIBRARY

export LD_LIBRARY_PATH=/path/instantclient:$LD_LIBRARY_PATH

like

export LD_LIBRARY_PATH=/oracle/instantclient_21_4:$LD_LIBRARY_PATH

Answer 2

Yes I solve it by adding a link of the library to the /usr/lib.

using the following command.

sudo ln -s /home/INSTANT_CLIENT/lib/libclntsh.so.11.1 /usr/lib/libclntsh.so.11.1

Answer 3

Copied from my answer here: Eclipse CDT Auto Include Shared Libraries

Run ldconfig as root to update the cache - if that still doesn't help, you need to add the path to the file ld.so.conf (just type it in on its own line) or better yet, add the entry to a new file (easier to delete) in directory ld.so.conf.d.

Answer 4

LIBPATH environment variable should be pointed to the lib32 folder which contains the libclntsh.

then you need to export LIBPATH variable before you run your application.

Answer 5

Make sure the Examples CD is installed. Make sure environment variable LD_LIBRARY_PATH is set, and the library file is accessible (permission-wise) for the user who you are logged in as.

If you have checked these and still get the error, please post the output of: strace ./a.out
