I am trying to install silk codec and siren on ubuntu.

When i try to make in codec directory i encounter this. 

Makefile:794: *** You must install libsilk-dev to build mod_silk.  Stop.

But when i run 

p   famfamfam-silk                                                              - a smooth, free icon set

p   libicon-famfamfam-silk-perl                                                 - module containing the famous FamFamFam Silk icon theme

p   python-flask-silk                                                           - FamFamFam Silk icon set for Flask applications

p   python-flask-silk-doc                                                       - FamFamFam Silk icon set for Flask applications (documentation)

Same is the case for siren.

 
Makefile:794: *** You must install libg7221-dev to build mod_siren.  Stop.

How can i install them on ubuntu?

Any pointer is much appreciated.

Thanks.
