jool/3.5.6 build fails with custom Debian 4.14.13 kernel #261

Closed skorpy2009 closed 6 years ago

skorpy2009 commented 6 years ago

I have build an own Debian 4.14.13 kernel. I used the Debian Stretch-Backports Source and config for the build, the only diff in the config is that I have enabled CONFIG_IPV6_SEG6_LWTUNNEL & CONFIG_IPV6_SEG6_HMAC .

Now DKMS ans kmod Build fails.

dkms autoinstall

Kernel preparation unnecessary for this kernel.  Skipping...

It's very similar to the errors I get when I try to compile Jool on a kernel installation that lacks kernel headers. I suppose that it might also happen if make fails to find the proper location of said kernel headers.

If your headers are located somewhere hard to find, do

$ make KERNEL_DIR=/path/to/your/headers

Here are the contents of my kernel headers directory, in case it helps:

ydahhrk@Nephenee:/usr/src/linux-headers-4.4.0-79-generic$ ls
arch    Documentation  include  Kconfig   mm              scripts   tools   zfs
block   drivers        init     kernel    Module.symvers  security  ubuntu
certs   firmware       ipc      lib       net             sound     usr
crypto  fs             Kbuild   Makefile  samples         spl       virt

Defining the headers Dir also does not help:

Oops, my bad. KERNEL_DIR should be the build/ directory inside the headers, not the root.

Try

$ make KERNEL_DIR=/usr/src/linux-headers-4.14.13/build

Still thinking, in case it doesn't work...

ydahhrk commented 6 years ago

Sorry; I'm mistaking the kernel headers directory with the modules directory. KERNEL_DIR is supposed to be the latter.

My correct KERNEL_DIR is /lib/modules/4.4.0-79-generic/build, not /usr/src/linux-headers-4.4.0-79-generic.

The correct contents of that directory is

ydahhrk@Nephenee:/lib/modules/4.4.0-79-generic/build$ ls
arch   crypto         firmware  init    Kconfig  Makefile        net      security  tools   virt
block  Documentation  fs        ipc     kernel   mm              samples  sound     ubuntu  zfs

Does the file /home/ffadmin/Jool-3.5.6/common/stateless/xlat.c exist?

It's kind of like that kernel is not enabled for compiling out-of-tree modules. Will try to read a little on that Debian variant and try to install it myself.

I don't think that the problem is the flags you enabled, because it fails as soon as it attempts to find the first listed .c to compile. It doesn't even manage to read the file.

Working...

All right, installing this is going to take a while so...

Could you please see if this minimalistic module compiles? No need to install or run it; just see if it compiles.

Giving me the instructions to install and compile that specific kernel would speed things up, too.

And finally: Can you send me the following file? You can find my e-mail in my profile if that medium is easiest for you.

chipping in - I am affected by this as well and I have access to the same machine. This is what happens when trying to compile the test module

ffadmin@jool1:~/test-module$ make
make -C /lib/modules/4.14.13/build M=$PWD

Makefile:9: die Regel für Ziel „all“ scheiterte
make: *** [all] Fehler 2

Edit: seeing how this module does not compile makes me think that this may not be a jool issue. Still input and help would be greatly appreciated.

christf commented 6 years ago

this is the requested makefile: http://paste.debian.net/1014987/

christf commented 6 years ago

After starting from scratch I was able to build the jool modules following the manual and your advice here to specify the location of the kernel tree. Thank you for your support.

My VM is still compiling :p

Works for me as well.

Just in case I need to do it again:
