Well, in another forum they told me that I should make a link from /usr/src/redhat/BUILD to /lib/modules/2.6.19-1.2911.fc6/build
and now the error is a little different:
[root@localhost ov51x-1.65-1.12-mark]# make clean
make -C /lib/modules/2.6.19-1.2911.fc6/build M=/usr/local/ov51x-1.65-1.12-mark clean
make: se ingresa al directorio `/usr/src/redhat/BUILD'
make: *** No hay ninguna regla para construir el objetivo `clean'. Alto.
make: se sale del directorio `/usr/src/redhat/BUILD'
make: *** [clean] Error 2
No hay ninguna regla para construir el objetivo clean means: There's no rule to construct the objective clean.
I think the source is installed, although I don't know very much of linux, when I updated the kernel, I think all the packages related to it were installed also, including the kernel-headers which I've seen they're installed.
How can I check if I have the source installed or not?
Thank you very much!
