DietPi-Set_Hardware | Compiling "i-sable-2km" module fails #2547

klasLiesen · 2019-02-14T08:38:31Z

I get error 2 and 'all' failed when selecting/installing soundcard i-sabre-2km in Dietpi-config.
Had no problems prior to Dietpi 6.20.

MichaIng · 2019-02-14T10:24:15Z

@klasLiesen
Thanks for your report.

The headers does not seem to be installed, which is strange according to the code as you should have received an error message about that before.

Please check:

uname -r # Your active kernel is indeed 4.14.79, which is current repo version since last November so should be
dpkg -l | grep raspberrypi-kernel # Kernel headers are installed and match the kernel version

klasLiesen · 2019-02-14T11:14:03Z

Thanks for your response.

Here is the result plus installation progress of the soundcard.

Sparade Terminal-utmatningar.txt

MichaIng · 2019-02-14T11:42:43Z

@klasLiesen
Everything as intended. Please check:

ls -l /lib/modules/4.14.79-v7+/ # Should contain the "source" dir
dpkg -S /lib/modules/4.14.79-v7+/source # Should list "raspberrypi-kernel-headers" as provider of this dir

If somehow this is not the case, please try to reinstall the kernel headers:
apt reinstall raspberrypi-kernel-headers

Otherwise I am a bid lost, since this worked well during tests. Perhaps the sources dir the Makefile expects needs to be changed, although very unlikely:
KERNEL_SRC = /lib/modules/$(shell uname -r)/source => KERNEL_SRC = /lib/modules/$(shell uname -r)/build

klasLiesen · 2019-02-14T17:44:41Z

I get this when trying the commands.

I have no problems with other soundcards, only the Sabre.

If we can't solv this, is it possible to get a download link to the last dist of DietPi prior to 6.20?

Thank for your help.
Hope you will find a way to help me with this.

/Klas

MichaIng · 2019-02-14T18:01:38Z

Ah sorry the APT reinstall command is: apt install --reinstall raspberrypi-kernel-headers

Other sound cards work fine, since their kernel modules/drivers are already included in the default Raspberry Pi kernel, so no module build required.

Okay I will check/verify this on my RPi later. In worst case you need to go the way with rpi-source which worked previously. However the APT package should render this obsolete, e.g. WireGuard module build works with the package as will without issues.

klasLiesen · 2019-02-14T19:10:46Z

Reinstall now worked fine but still no luck with the Sabre card i'm afraid.

/Klas

MichaIng · 2019-02-14T19:28:32Z

Okay, please try the following to switch the source dir, according to most guides this should be /lib/modules/$(uname -r)/build instead of /lib/modules/$(uname -r)/source.
Simply create a symlink to redirect to the correct source dir:
ln -s /lib/modules/$(uname -r)/build /lib/modules/$(uname -r)/source

If this works we need to commit to the module dev to switch this in the Makefile to match current raspberrypi-kernel-headers file structure.

klasLiesen · 2019-02-14T20:24:26Z

Didn't work all the way.

/Klas

MichaIng · 2019-02-14T22:38:16Z

@klasLiesen
gcc: Command not found

Do: G_AGI g++-4.9

The symlink build => source btw. is correct. rpi-source does the same, respectively links to both from the same /usr/src/linux-headers-* dir: https://github.com/notro/rpi-source/blob/master/rpi-source#L340-L341

Dev notes:

The gcc version need to match the one from:

2019-02-15 00:05:40 root@micha:/tmp# cat /proc/version
Linux version 4.14.79-v7+ (dc4@dc4-XPS13-9333) (gcc version 4.9.3 (crosstool-NG crosstool-ng-1.22.0-88-g8460611)) #1159 SMP Sun Nov 4 17:50:20 GMT 2018

So 4.9.3 currently. This should be the one provided by Raspbian Stretch repo, but e.g. on Buster gcc/g++-4.9 installs v4.9.4 which means Buster breaks this build until the raspberrypi.org repo is ported to Buster, I guess, where for sure the kernel will be build on 4.9.4 or hopefully modern e.g. v8 already.
rpi-source does this check and reports error on mismatch (https://github.com/notro/rpi-source/blob/master/rpi-source#L174-L196), but raspberrypi-kernel-headers does not include the c compiler.
Ref: https://github.com/SatoruKawase/I-Sabre-K2M/blob/master/INSTALL.md
Deps: device-tree-compiler <<< libraspberrypi-bin and gcc-4.9 <<< g++-4,9

Hmm:

Selecting previously unselected package gcc-4.9.
Preparing to unpack .../08-gcc-4.9_4.9.3-14_armhf.deb ...
Unpacking gcc-4.9 (4.9.3-14) ...

So gcc is installed, and the correct version as expected.

But again make reports:

Entering directory '/usr/src/linux-headers-4.14.79-v7+'
$cripts/gcc-version.sh: line 26: gcc: command not found

Works well here (x86 VM):

root@VM-Stretch:/lib/modules/4.9.0-8-amd64/source/scripts# ./gcc-version.sh gcc
0603

@klasLiesen
Thanks for testing.

What do those say:

command -v gcc
gcc --version

@Fourdee
Looks like we missed testing this and rpi-source indeed includes some checks and steps that are missing when installing the raspberrypi-kernel-headers. While not required for WireGuard obviously, here it is.

While I definitely don't want to revert to rpi-source method (even it's dev renders it obsolete and only useful as companion to rpi-update for testing/dev reasons), but we need to figure out the missing steps here and remember for other module builds as well. At least the gcc/g++ 4.9 install is very common for this kernel and I wonder why it is not a dependency of the header package. Same for the ../source => ../build symlink 🤔. On x86 both is available, pointing to different directories, where on RPi this is merged, but obviously module Makefiles can expect both...

klasLiesen · 2019-02-15T13:16:02Z

Hope this is what you need.

Just checked, indeed gcc binary to version link is not created automatically .... 🙄:

On RPi, the package contains:

@klasLiesen
So do: ln -s /usr/bin/gcc-4.9 /usr/bin/gcc
And to be failsafe as well: ln -s /usr/bin/g++-4.9 /usr/bin/g++

To check:

Is there a way to force a specific gcc binary for the make command?
Because the above would not work or break other gcc versions, if installed...
Perhaps we should do the same with g++? Although I don't see where this is actually used...

klasLiesen · 2019-02-15T14:43:41Z

We have a success.

I used: ln -s /usr/bin/gcc-4.9 /usr/bin/gcc

and then selected/installed soundcard i-sabre-2km in Dietpi-config.

Should I do: ln -s /usr/bin/g++-4.9 /usr/bin/g++ as well?
/Klas

MichaIng · 2019-02-15T15:06:45Z

@klasLiesen
Great finally 😅.

Nope g++ is not required then. All this was only to build the kernel module and this has obviously finished successfully.

Hmm even the official docs state to install g++ as well, it indeed seems not to be required. However this is something we can test ourself to fine tune the install/build script.

As well we can test if make CC=gcc-4.9 is sufficient to not mess with possibly already installed different gcc versions.

@Fourdee
Might you find some time to test the above (also mentioned within the open PR)?

klasLiesen · 2019-02-15T16:59:03Z

I tried: ln -s /usr/bin/g++-4.9 /usr/bin/g++ and selected/installed soundcard i-sabre-2km in Dietpi-config. I got no complains but the soundcard did not show in Roon.

I then: apt install --reinstall raspberrypi-kernel-headers
G_AGI g++-4.9
ln -s /usr/bin/gcc-4.9 /usr/bin/gcc
and selected/installed soundcard i-sabre-2km in Dietpi-config.
(Don't know if that's the right way to do it)
Soundcard was back in Roon and music is playing.

Thanks for all help and have a nice weekend.

Klas

MichaIng · 2019-02-15T17:16:17Z

@klasLiesen
Jep ln -s /usr/bin/gcc-4.9 /usr/bin/gcc or giving this information inside the code to the make command is definitely required. The g++ binary obviously doesn't play a role here, also I couldn't find any g++ calls within the scripts in the kernel source so far...
