Hi,
I have write a 'hello, world!' module which is in a directory
rather than the kernel source tree. I compiled it by:
make -C /usr/src/linux SUBDIRS=$PWD modules
and installed it by:
make -C /usr/src/linux SUBDIRS=$PWD modules_install
I find it was installed at /lib/modules/2.6.34/extra. Then, I invoked
modprobe hello.ko
to load this module, but get a message:
FATAL: Module hello.ko not found.
It seems that my module is not in the modprobe's search path. Is that
true? If so, how can I configure its search path?

modprobe uses modules.dep to translate module names into module
locations. You can either manually add an entry into that file - found
in /lib/modules/$(uname -r)
or you can rerun depmod on your device (if its available).
Alternatively, you can insmod your module bu providing a fully
qualified path to the .ko file. insmod doesn't do any dependancy
checking, so it just fails if you need symbols from some other module
which isn't loaded.

I second that...... it is the easiest and the most straightforward way
to rebuild modules.dep.
