menuconfig: can not select scsi device support

menuconfig: can not select scsi device support

[robert rottermann]

Hi there,
I am working trough a book on embeded systems (embeded linux by J.Quade)
There in the chapter about building a new kernel is suggested to select Device 
Drivers-> SCSI device support -> a number of subslections.

Now, when I start menuconfig I find Device Drivers-> SCSI device support, but 
selecting it produces an empty page.

Why is that so?
Do I have to add other elements to the configuration process?

I am using linux-3.19.

Thanks
robert

You can find out dependencies for needed options by pressing '/' (to search) and then typing your option.

My guess is you're missing BLOCK. If BLOCK is not set see you'll see
       SCSI device support  ----

in the Device Drivers page of "make menuconfig". And if BLOCK is set
you'll see
       SCSI device support  --->

(Yes, the difference is rather subtle.) Then you should see a non-empty
page if you select that:
    [ ] RAID Transport Class (NEW)
    [ ] SCSI device support (NEW) 

(And, yes, there are two entries labeled "SCSI device support".) You can
(probably) set BLOCK in the main menu under
    [ ] Enable the block layer  ----

Hope this helps,
