Issues with installing unixODBC (Oracle linux 6)

Question

"4.5 Compiling the Oracle ODBC Driver Demos
If you plan to compile and run the Oracle ODBC Driver demos, then follow these steps:
1.
If you do not have unixODBC DriverManager installed, then download it from the following Web site:
http://www.unixodbc.org/
2.
Set the ODBCDM_HOME environment variable to point to the directory where you installed DriverManager.
3.
Run the following make file to compile the Oracle ODBC Driver demos:
make -f demo_xe.mk buildodbcdemo ODBCDM_HOME=DriverManager_location
When trying to execute this :
make -f demo_xe.mk buildodbcdemo ODBCDM_HOME=DriverManager_location
[root@localhost ~]# cd /u01/app/oracle/product/11.2.0/xe/rdbms/demo
[root@localhost demo]# make -f demo_xe.mk buildodbcdemo ODBCDM_HOME=/opt/unixODBC-2.3.1
make: *** No rule to make target `odbcdemo.o', needed by `buildodbcdemo'. Stop.
Obviously the the file is missing what now ? Do I need to do this part of the cookbook anyway?
Ive installed it through the repo tho:
P.S. OK, dl-ed from the repo

Answer 1

according to my post above:
"make -f demo_xe.mk buildodbcdemo"
[root@localhost demo]# make -f demo_xe.mk buildodbcdemo ODBCDM_HOME=/opt/unixODBC-2.3.1/
make: *** No rule to make target `odbcdemo.o', needed by `buildodbcdemo'. Stop.
[root@localhost demo]# pwd
/u01/app/oracle/product/11.2.0/xe/rdbms/demo
[root@localhost demo]# ls
cdemo81.c demo_xe.mk occidemo.sql occidml.cpp occiobj.cpp occiobj.typ
[root@localhost demo]#
I think they are put here, right ?
