Desktop Screen Recorder for RHEL 5

Hi ,

Many times we need to record our desktop so that we can later view and share same videos with others.
Here is a little tutorial on how to do it..

1) Need to have setup RHEL repository
2) Download  recordmydesktop

Installing recordmydesktop on RHEL5
---------------------------------------
step 1 :  unzip recordmydesktop.tar.gz using --> tar -xvf recordmydesktop.tar.gz

step 2 : go to extracted folder.

step 3 : ./configure

step 4 : make

make: *** No Rules to make target `install` . Stop.

HERE THE PROBLEMS STARTS!

This is what i didn't expected basically in my case i followed below steps :

./configure | grep "error"

Now you will get list of dependencies thats what we need to install.

in case of RHEL5 all these dependencies are available in  RHEL5 repositories.

just install it like : 


yum install -y (PACKAGE NAME SPECIFIED IN ERROR)  


Again type : ./configure | grep "error"

Repeat above steps till above command gives no output.

Thats how you solved dependencies for recordmydesktop software

Now simply fireup command : recordmydesktop


Your screen recording gets started!

Thats It!...Enjoy Recording
