[SOLVED] /lib/modules/4.15.0-29-generic/build: No such file or directory

I am trying to install DPDK on Alpine Linux in the Docker container.

During the installation, I am getting the following error:

Quote:

/lib/modules/4.15.0-29-generic/build: No such file or directory. Stop.

Is there equivalent directory in Alpine Linux to link it with this one?

How can I solve this problem? What is this directory used for?

Thanks in advance

Anyone has an idea how to solve this?

This directory is a symlink to the (running) kernel sources.
Dunno about Alpine, but in general it should be something like:

Code:

/lib/modules/4.15.0-29-generic/build  -> /usr/src/4.15.0-29-generic

Maybe you need to install some package containing the kernel sources, of your running kernel (like this
Note: it's for for kernel 4.14.78-r0)

I solved this by installing kernel modules from here and then link /lib/modules/4.15.0-29-generic/build to /srv/linux-4.9.4 directory

If your problem is solved please mark the thread solved. Also please doon't forget to say thanks if someone helped....

I don't think linking 4.15.xx to 4.9 is a good idea. That may cause strange side effects later (for example an "unexpected" segmentation fault).
In the dockerfile (you linked) in line 26 you can specify the version of kernel. I would suggest you to modify it and start over again.
