libaio so 1 cannot open shared object file

Question

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 - gt  libaio so 1 0 1 -rwxr-xr-x  1 root root 2632 Sep 16  2005  usr lib libaio so 1 0 0 -rwxr-xr-x  1 root root 2628 Sep 16  2005  usr lib libaio so 1 0 1   Output of ldd hello   libocilib so 3   gt     ocilib-3 9 3 src  libs libocilib so 3  0x0000002a95558000  libc so 6   gt   lib64 tls libc so 6  0x0000003811200000  libclntsh so 11 1   gt     instantclient 11 2 libclntsh so 11 1  0x0000002a956c4000   lib64 ld-linux-x86-64 so 2  0x000000552aaaa000  libnnz11 so   gt     instantclient 11 2 libnnz11 so  0x0000002a97f56000  libdl so 2   gt   lib64 libdl so 2  0x0000003811500000  libm so 6   gt   lib64 tls libm so 6  0x0000003811700000  libpthread so 0   gt   lib64 tls libpthread so 0  0x0000003811b00000  libnsl so 1   gt   lib64 libnsl so 1  0x0000003819000000  libaio so 1   gt  not found   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

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

I had to do the following  in Kubuntu 16 04 3     Install the libraries  sudo apt-get install libaio1 libaio-dev Find where the library is installed  sudo find   -iname  libaio a  -type f --  resulted in  usr lib x86 64-linux-gnu libaio a Add result to environment variable  export LD LIBRARY PATH   usr lib oracle 12 2 client64 lib  usr lib x86 64-linux-gnu

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

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

User · Answer

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
