I have a simple test program that when I run I get:
./hello: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
I link it like this:
$(CC) $(CCFLAGS) -o hello hello.o -L../ocilib-3.9.3/src/.libs -L../instantclient_11_2 -locilib
My LD_LIBRARY_PATH contains this:
LD_LIBRARY_PATH=../ocilib-3.9.3/src/.libs:../instantclient_11_2:/usr/lib
/usr/lib looks like this:
Linux$ ls -l /usr/lib/libaio*
lrwxrwxrwx 1 root root 15 Nov 5 2008 /usr/lib/libaio.so.1 -> libaio.so.1.0.1

-rwxr-xr-x 1 root root 2628 Sep 16 2005 /usr/lib/libaio.so.1.0.1

I'm hoping that I'm missing something simple here. The oracle instantclient package appears to require libaio, but that seems to be installed already so what's the problem?

It looks like a 32/64 bit mismatch. The ldd output shows that mainly libraries from /lib64 are chosen. That would indicate that you have installed a 64 bit version of the Oracle client and have created a 64 bit executable. But libaio.so is probably a 32 bit library and cannot be used for your application.
So you either need a 64 bit version of libaio or you create a 32 bit version of your application.
I had the same problem, and it turned out I hadn't installed the library.
this link was super usefull.
I had to do the following (in Kubuntu 16.04.3):
sudo apt-get install libaio1 libaio-devsudo find / -iname 'libaio.a' -type f --> resulted in /usr/lib/x86_64-linux-gnu/libaio.aexport LD_LIBRARY_PATH="/usr/lib/oracle/12.2/client64/lib:/usr/lib/x86_64-linux-gnu"Install the packages:
sudo apt-get install libaio1 libaio-dev
or
sudo yum install libaio
I'm having a similar issue.
I found
conda install pyodbc
is wrong!
when I use
apt-get install python-pyodbc
I solved this problem?
Here on a openSuse 12.3 the solution was installing the 32-bit version of libaio in addition. Oracle seems to need this now, although on 12.1 it run without the 32-bit version.
In case one does not have sudo privilege, but still needs to install the library.
Download source for the software/library using:
apt-get source libaio
or
wget https://src.fedoraproject.org/lookaside/pkgs/libaio/libaio-0.3.110.tar.gz/2a35602e43778383e2f4907a4ca39ab8/libaio-0.3.110.tar.gz
unzip the library
Install with the following command to user-specific library:
make prefix=`pwd`/usr install #(Copy from INSTALL file of libaio-0.3.110)
or
make prefix=/path/to/your/lib/libaio install
Include libaio library into LD_LIBRARY_PATH for your app:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/your/lib/libaio/lib
Now, your app should be able to find libaio.so.1
