The Makefile will build the files for you - 'make' is a well-known process  
for compiling/building systems.

You don't disclose what distribution you are using but, for a recent  
Ubuntu, try the following from a command line/terminal;

1. Ensure you have a compilation environment installed, ie. "gcc -v" &  
"make -v" both return some version info. I believe "sudo app-get install  
build-essential" should set this up for you if these commands are  
unrecognised.

2. Ensure you have python installed, ie. "python -v" returns something.  
"sudo apt-get install python" should set this up if you don't.

3. Also copy the Makefile to the same directory as the other files.

4. cd to the directory containing your files. "sudo make" should now  
compile the 2 cpp files & install executables "silence" & "catagrower"  
into /usr/local/bin.

5. Move silence.py to /usr/local/bin

6. Test it using "silence.py --chanid 1004 --starttime 20130117220000  
--loglevel debug", as per the wiki. Use a relevant chanid/starttime and it  
should actually do something. To get Myth to use it automatically the  
'Advert-Detection command' is on one of the last pages of  
mythtv-setup/General

Obviously this is all dependent on your system, user, permissions etc. If  
you still have problems post back with your distribution info, the  
versions of gcc & python you are using and the errors you're getting.
