When compiling 5.5 on Linux, they way releases are done
using cmake .. -DBUILD_CONFIG=mysql_release
,as documented  here http://forge.mysql.com/wiki/CMake and also described here

the build fails
CMake Error at cmake/build_configurations/mysql_release.cmake:123 (MESSAGE):
 aio is required on Linux

and does not give user any hint what to do with it.

How to repeat:
On any Linux installation, where libaio is not installed (and it is not installed by default)

mkdir bld
cd bld
cmake .. -DBUILD_CONFIG=mysql_release

Suggested fix:
Either issue only a warning, or give a good description how to fix the situation, e.g
"aio is required on Linux. To install : on Debian and derivates use 'apt-get
install <libname>', on Redhat and derivates use 'yum install <libname>', on Suse use 'zypper install <libname>"

Sunanda, could you take a look at this?

A warning is not appropriate, we need the build to fail as shipping a release with this feature missing is unacceptable, and we need to catch it early.  Instructions for Red Hat, Debian and SuSE should suffice (make sure that the commands are on their own line for easy cut-and-paste, and add some whitespace around so that it doesn't get lost in the cmake output noise).

For Ubuntu/Debian, the required packages are 'libaio1' and 'libaio-dev'.

Noted in 5.5.8 changelog.

When configuring the build with -DBUILD_CONFIG=mysql_release on
Linux, libaio is required, but the error message if it was missing
was uninformative.

I have installed libaio-dev on my Debian 6.0 but I still get that damn error/warning or whatever. Should I refresh something?

You may have to remove existing CMake cache files, or start a fresh build in a fresh directory.
