Calling MATLAB from C

My main aim is to call MATLAB engine from a C program. do
some computation in MATLAB and return back the result to the
C program. But just at the start i am facing a problem.

I am using MATLAB R14 SP3 in Linux.
I cud not run the example engdemo.c from command prompt!! i
had changed the #include "engine.h" to point to the same
file in the include directory. after trying to compile the
example, i run into the following error:

[root@narmada etc]# gcc engdemo.c -o engdemo
/tmp/ccsXH5nc.o: In function `main':
engdemo.c:(.text+0x4a): undefined reference to `engOpen'
engdemo.c:(.text+0xa3): undefined reference to
`mxCreateDoubleMatrix'
engdemo.c:(.text+0xb1): undefined reference to `mxGetPr'
engdemo.c:(.text+0xe8): undefined reference to `engPutVariable'
engdemo.c:(.text+0xfb): undefined reference to `engEvalString'
engdemo.c:(.text+0x10e): undefined reference to `engEvalString'
engdemo.c:(.text+0x121): undefined reference to `engEvalString'
engdemo.c:(.text+0x134): undefined reference to `engEvalString'

etc..........

I tried to solve it on my own, bt in vain.
i come to know that theres a linking problem, bt how to
solve it?

Please help me if you can !!
Please !!!

Thanking You
