/lib/modules/<onlKernelVersion>/build Path Not Found

[torombolo17]

Hello! I'm trying to install some software that is trying to access the path "/lib/modules//build" . I believe I have to install the headers, but I don't know where to find these. Based on the command uname -srm my kernel version is Linux 4.14.109-OpenNetworkLinux x86_64. Do I have to install the linux generic headers, or are there some specific headers I need to install?

Thanks!

Exactly the same question, hope for answer !

A person suggested here(line 382-392) intstalling a onl-kernel .deb package and then creating a symlink to the mbuilds/ directory of the installed package. But, I'm not sure if onl-kernel .deb packages are directly available. Does anybody know?

building all .deb packages probably creates onl-kernel .deb packages. I tried following this section on a Debian 9 machine, unfortunately, it raises the following error (similar to #732) and doesn't finish.

I later found that when I built ONL installer on Debian 9 machine, an mbuilds/ directory was created in $ONL/REPO/stretch/extracts/onl-kernel-4.9-lts-x86-64-all_amd64/usr/share/onl/packages/amd64/onl-kernel-4.9-lts-x86-64-all directory.

I zipped this mbuilds/ dir, transferred it to switch CPU where ONL is installed and extracted its contents in /lib/modules/<onlKernelVersion>/build directory. Then the error /lib/modules/<onlKernelVersion>/build path not found was gone.
