libaio.so.1：无法打开共享库文件

我有一个简单的测试程序，运行时会得到：

./hello: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

我这样链接：

$(CC) $(CCFLAGS) -o hello hello.o -L../ocilib-3.9.3/src/.libs -L../instantclient_11_2 -locilib

我的LD_LIBRARY_PATH包含以下内容：

LD_LIBRARY_PATH=../ocilib-3.9.3/src/.libs:../instantclient_11_2:/usr/lib

/ usr / lib看起来像这样：

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

ldd hello的输出：

libocilib.so.3 => ../ocilib-3.9.3/src/.libs/libocilib.so.3 (0x0000002a95558000)
libc.so.6 => /lib64/tls/libc.so.6 (0x0000003811200000)

libaio.so.1 => not found

我希望这里缺少一些简单的东西。oracle Instantclient软件包似乎需要libaio，但似乎已经安装了，那么问题是什么？
