i don’t believe you actually have a path like

/lib/modules/$(uname -r)/build

because “$(uname -r)” is not a ‘normal’ directory name, instead it is
a normal command line command and i have no idea why it appears in
your path…

do you know why it is there? it sure looks like a typo to me, and i
would expect it to result in a error as you say it did…take that
part out and try again.

perhaps you were supposed to substitute in the name of a directory
after running ‘uname -r’, like here i would sub in
“3.0.58-28-desktop” (which is my running kernel)!

Try this, and you’ll see that there’s nothing wrong with the command

laptop:~> echo $(uname -r)

The info you provide is by far not enough to help you. Please state your openSUSE version, what’s installed to build a kernel module (I guess that’s what you’re trying).

In bash that’s perfectly acceptable - it’s command substitution.

jhenderson@lamuella:~> cd /lib/modules/$(uname -r)/
jhenderson@lamuella:/lib/modules/3.4.28-2.20-desktop>
