To install the library, execute the command: make prefix=`pwd`/usr install which will install the binaries and header files into the directory usr. Set prefix=/usr to get them installed into the main system. Please note: Do not attempt to install on the system the "libredhat-kernel.so" file. It is a dummy shared library provided only for the purpose of being able to bootstrap this facility while running on systems without the correct libredhat-kernel.so built. The contents of the included libredhat-kernel.so are only stubs; this library is NOT functional for anything except the internal purpose of linking libaio.so against the provided stubs. At runtime, libaio.so requires a real libredhat-kernel.so library; this is provided by the Red Hat kernel RPM packages with async I/O functionality.
