[Rtai] Error when Build a Real Time Application

[Diego Rodrigues]

Hi everybody, I'm following the "Building Your Way Through RTAI" guide by
João Monteiro which explain step by step how to Build a real time
application. I've done all the steps and when I was on "Build the
Application" the step 5 I created a file named Makefile with this content:

sample: rt_skelet.o functions.o
        gcc -L /usr/realtime/lib -lpthread  -O2 -I /usr/realtime/include
rt_skelet.o
            functions.o -o sample
rt_skelet.o: rt_skelet.c functions.c globals.h
        gcc -c -L /usr/realtime/lib -O2 -I /usr/realtime/include rt_skelet.c
functions.o: functions.c globals.h
        gcc -c -L /usr/realtime/lib -O2 -I /usr/realtime/include functions.c
clean:
        rm *.o
        rm sample

when I executed the Makefile I had this output:

root at rodrigues:~/workspace/MyFirstRTAIAplication# ./Makefile
./Makefile: line 1: sample:: comando não encontrado
gcc: rt_skelet.o: Arquivo ou diretório inexistente
./Makefile: line 3: functions.o: comando não encontrado

./Makefile: line 11: clean:: comando não encontrado
rm: imposível remover `*.o': Arquivo ou diretório inexistente
rm: imposível remover `sample': Arquivo ou diretório inexistente


does anybody know what is wrong?

I have the RTAI 3.6 on Ubuntu 7.10 (kernel 2.6.22-14-generic)

excuse for my english.
