i have a problem to add a file to /proc does there is a simple way or

it or direct me to a how to a free method that is simple and accurate
    

Creating a file in /proc is going to require a kernel module or a
patched kernel. Chapter four[1] of _Linux Device Drivers_[2] describes
how to create a file in /proc.

That said, it's no longer considered good form to add anything to /proc.
The new home for this information is the /sys filesystem or debugfs.
LWN has a quick guide for using debugfs[3].

thanks for your reply but i have no straight forward how to in steps  or 
in how to compile or run that is why i'm warring of carshing the system
in the link below
http://tldp.org/LDP/lkmpg/2.6/html/x769.html
i get those errors and i don't konw what is the cause  here is how i compile
====================================================
export srcf="/data/hatem/work/c/project/learning/source/010"
export objf="/data/hatem/work/c/project/learning/object/010"
cd $srcf
gcc   -g  -o  proc.bin proc.c
mv -f ./proc.bin  $objf
cd $objf
./proc.bin

am i suppose to change the header files for that to work can you help in 
that thanks in advance
the error message is attached
