The compile and link failed.

[cee@localhost ~]$ lx11
bash: lx11: command not found

one of my friend using the same commands is able to compile it well but its not happening on my desktop...suggestion please .

Welcome to LQ.
'-lX11' : Means libX11.so

Please install the libX11 development package.
I.e. all packages required for compiling files / apps must be (lib)<name>-dev(el)

Ubuntu, Debian : apt-get install libx11-dev
Fedora, CentOS : yum install libX11-devel

*** Note : You will need all the other libs too :
-lXext -lcairo -lfontconfig -lpixman-1 -lfreetype -lexpat -lpng -lz -lpthread -lbz2 -lXrender

error in bz2
 

i get the following error
[root@localhost lib]# sudo yum install libbz2-devel
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirror.internode.on.net
* extras: ftp.swin.edu.au
* updates: ftp.swin.edu.au
Setting up Install Process
No package libbz2-devel available.

Which Fedora / CentOS etc. are you using ?

Finding a package : yum search <name> ( or part of name.)

Finding the package name that provides <file name> :
yum provides */libbz2.so

# yum install bzip2-devel
