How create and apply a patch in one directory ??

[andre duarte bueno]

PS:
Sorry if appears as a base question, but all book about linux 
programming not cover patch
in a directory, only on an individual file.


1) I create the directory
/tmp/teste

2) then input files
address@hidden tmp]$ ls teste
CVS                   List-15-2-TCirculo.cpp      
List-19-1-TPonto.h           List-40-2-makefile-libtool      teste.patch
doxygem.config        List-16-2-TElipse.h         
List-19-2-TPonto.cpp         List-40-3-makefile-libtool.uso  uso-makefile
List-11-5-TPonto.h    List-16-3-TElipse.cpp       
List-39-4-makefile           List-40-4-temposprocessamento
List-11-6-TPonto.cpp  List-17-1-Polimorfismo      
List-39-5-makefile.uso       makefile
List-15-1-TCirculo.h  List-17-1-Polimorfismo.cpp  
List-40-1-libtool--help.txt

3) I create a new version of teste
cd /tmp
cp -R teste teste-r2

4)
I modify the file teste-r2/List-17-1-Polimorfismo.cpp including new 
lines of code.

5) I create a diff file using
cd /tmp
diff  teste teste-r2 > patch_file

6) I use
cd /tmp
patch -p0 < patch_file

BUT the patch not run OK ???

the message are

address@hidden tmp]$ patch -p0 < patch_file
can't find file to patch at input line 3
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|Common subdirectories: teste/CVS and teste-r2/CVS
|diff teste/List-17-1-Polimorfismo.cpp teste-r2/List-17-1-Polimorfismo.cpp
--------------------------
