Salve a tutti, sto cercando di creare i driver per la scheda PRMISE sx6000 con fedora core 1.b..

Ho trovato questo semplice tutorial per la creazione dei draiver http://members.rogers.com/sith.warrior/build.htm
ma ci sono alcune cose che non mi sono chiare.....

Inazitutto cosa significa:

...and be sure that it is set for an INDEP build by modifying the Makefile..

se questo e il mio make file dove devo settare "INDEP" ?

clean:

rm -f pti_st.o pti_st.o.boot 2>&1 >/dev/null



insmod:

-rmmod pti_st

-insmod scsi_mod

-insmod sd_mod

-insmod pti_st.o

poi un altro punto oscuro e nell read me della creazione del driver:

...Before building the

driver code, you have two choices:

1.) If you want run the driver in current kernel version and the kernel

source directory is something like '/usr/src/linux-x.x.xx/', the

'x.x.xx' is the current kernel version, then you can just run make

command in the driver source code directory.

2.) If you don't want run the driver in current kernel version, then you

must tell the make program where is the linux kernel source directory.

thus, you can run 'make KERNEL_SOURCE_DIR=/usr/src/linux-x.xx.xx'

(without the quotation marks).

A scanso di equivoci devo usare l' ozione 2 pel il kernel di BOOT e l' opzione 1 per il kernel 686 (Giusto?)

Scusate se faccio domande stupide ma è da poco che sono passato al mondo LINUX!
Un saluto a tutti JUNK!

Quando compilo il driver il makefile mi genera questa linea di codice (linux-2.4.22-1.2115.nptl che penso sia quello di BOOT):

gcc -c pti_st.c -o pti_st.o -D__KERNEL__ -DMODULE -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -Wno-unused -pipe -I/usr/src/linux-2.4.22-1.2115.nptl/include -I/usr/src/linux-2.4.22-1.2115.nptl/drivers/scsi -march=i386 -mpreferred-stack-boundary=2

secondo voi e compialato INDEP ???
