[fw407]

i am trying to use a solver of FSI.but i do not know how to do it,so i first follow steps i found on a website to create a solver by modify a pre-defined solver,here is the address:
http://www.csc.fi/english/research/s...enfoam/modsol/

at the beginning,everything is fine,
but when i inuput "emacs Make/files"
and the terminal tells me:
The program 'emacs' can be found in the following packages:
* emacs21-nox
* emacs22-gtk
* emacs22
* emacs-snapshot
* e3
* emacs-snapshot-nox
* emacs21
* emacs22-nox
* jove
* emacs-snapshot-gtk
Try: sudo apt-get install <selected>
bash: emacs: command not found

i do not what is the problem,so i creat a file manully which the coresponding step on the website want me to creat
after that i input "wmake",problems also comes up
,the terminal tells me:

these are just part of the errors ,for it is too long.sorry about that

i know if everything was fine,i should get an executable in the
/home/fw407/OpenFOAM/fw407-1.4.1/applications/bin/linuxGccDPOpt directory


So could anyone give me some advice on how to deal with it?
