fedora 14 ? or fedora 16 ?
what is it ?
Fedora 14 is past it's end of life
so if this is 14 then first install fedora 16
and from where did you get the source for " mdadm-3.2.3 "

mdadm-3.2.2-13.fc16.x86_64.rpm
is already part of fedora 16

and the source for it IS in the fedora source repo
so there is no need to rebuild something that is installed ( or can be installed from yum )

I have installed it by using make and make install command.It is installed(have checked it)and am using fedora16. I don't know how create raid array for raid6 and raid 5. I have followed a link http://djlab.com/2012/02/mdadm-cheat-sheet/
but the output is coming like that
mdadm --create --verbose /dev/md0 --level=1 /dev/sda1 /dev/sdb2
mdadm: no raid-devices specified.

unless you MUST HAVE and MUST USE "mdadm-3.2.3" the 3.2.3
it IS ADVISABLE to use what is in the fedora 16 repo

that is "mdadm-3.2.2-13.fc16"

uninstall the source build one
Code:
make uninstall
and use yum
Code:
su -
yum install mdadm
if it was already installed before you overwrote it with a different version you will get a " already installed - nothing to do " ERROR

then use the reinstall option for yum
see the help and man page
Code:
yum --help
---- and then this  ---
man yum
then for the source just install the

you want to use the code in the source to BUILD and make some unknown project ( new program ? ) but you do not know how to use it ????
--- or what - this bit us very confusing ------

then install the devel package
from a search

yum search mdadm

c-sharp might be a very big problem
you will need " mono " and it is about 5 versions behind the Microsoft " .net framework "
you might want to port ALL the code to the standard c++ first
