memcached installation error

when i try to install memcached in windows xp with xampp by command line as the follow:

pecl install memcached

i recive this error in my command window :

Error : The DSP memcached.dsp does not exist.

1 - what is the problem ?

2 - and if its not solvable how to compile the memcached package when download it directly from the pecl ?

You might look here for a related problem. It looks like there are limited extensions available for PHP Windows, and memcached has probably not been built for pecl4win.

There is a link on the other question on how you can build your own PHP on Windows, or else you might ask if someone else could make a build on the mailing list: pecl-dev at lists.php.net
