NEWBIE : can't find /lib/modules/2.4.17/modules.dep error

[Punj, Arun]

Folks,

I upgraded the 2.4.7-10 kernel that comes with RH7.2 to 2.4.17. 
[ I could compile it fine and grub is able to load it too...]

However, I see the error : can't find /lib/modules/2.4.17/modules.dep
multiple times.

Afcourse there is no such file or directory. I suspect that this
directory and file should have been created when I compiled 2.4.17 
kernel but it did not. ( I did make bzImage )

Can you please point out the problem and also the effect of this
error because I cannot see any side effect of this error.

Thanks
Arun

Sounds like you didn't make or install modules. Most kernels these days
are best built using modules for device drivers and such that are loaded
on-demand during runtime, instead of being part of a big 'monolithic'
kernel. This saves space in memory and has some other benefits (although
this is open to debate).

`make bzImage` makes just the 'monolithic' part of the kernel, while `make
modules` and `make modules_install` handle building and installing modules,
and should create the proper directories and put in the appropriate files.

If you did execute the modules commands (as root, of course), the problem
might be in your module loader program suite (insmod, lsmod, etc.). Old
versions of the program don't work with newer kernels. I'm not a RedHat user
so I wouldn't know about that, but you could check their site and download
the latest RPM if that seems to be the problem.

You need to make modules and make modules_install too :)

Thanks, You are right I did not do a make modules_install. 

However, the thing is  - my system was working normally in so far as I can
tell even without doing make modules_install !!! Maybe I am not using any
of dynamically loading drivers???

Thanks a ton eric and all who have helped.
