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 -> 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 => ../ocilib-3.9.3/src/.libs/libocilib.so.3 (0x0000002a95558000) libc.so.6 => /lib64/tls/libc.so.6 (0x0000003811200000) libclntsh.so.11.1 => ../instantclient_11_2/libclntsh.so.11.1 (0x0000002a956c4000) /lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000) libnnz11.so => ../instantclient_11_2/libnnz11.so (0x0000002a97f56000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003811500000) libm.so.6 => /lib64/tls/libm.so.6 (0x0000003811700000) libpthread.so.0 => /lib64/tls/libpthread.so.0 (0x0000003811b00000) libnsl.so.1 => /lib64/libnsl.so.1 (0x0000003819000000) libaio.so.1 => 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?

Answer 1

Install the packages:

sudo apt-get install libaio1 libaio-dev 

or

sudo yum install libaio
