kernel compilation error

marekfila

Hello,
I would like to ask you to solve my problem.
I wanted to compile the ubilinux kernel for using I2S
and the compilation ends with an error. Where can there be a mistake?
Thank you.

appears at the end of the compilation:

dpkg-source: info: use the '3.0 (quilt)' format to have separate and documented changes to upstream files, see dpkg-source (1)
dpkg-source: error: unrepresentable changes to source
dpkg-buildpackage: error: dpkg-source -i.git -b linux has given error exit status 1
scripts / Makefile.package: 73: 'deb-pkg' target failed
make [1]: *** [deb-pkg] Error 1
Makefile: 1426: instructions for the deb-pkg target failed

Hi @marekfila

do you mean the ubilinux kernel for Ubuntu that you can find on our PPA?

marekfila

Hello,
yes, I found it on your PPA.
I follow the instructions from the web: https://thesofproject.github.io/latest/getting_started/build-guide/build-from-scratch.html#build-linux-kernel
Thank you.

Are you adding additional patches changes to the source from our PPA?

Or is the error coming from the original source code downloaded?

marekfila

I use the original ubilinux source code from www.emutex.com. Unfortunately, the download link is not functional.
And I followed the instructions here: https://thesofproject.github.io/latest/getting_started/setup/setup_up_2_board.html

Hi @marekfila

ubilinux is not supported anymore and for this reason you cannot find the source code or link for the image

Ubuntu is currently supported so you should setup a system using ubuntu from our tutorials: https://wiki.up-community.org/Ubuntu

Then the kernel build guide is checking out a kernel from a specific repository and branch that has been developed by the SoF team, which we are not responsible for.
The best way to understand why you are getting this error is to contact them directly, describing your issue via the github project: https://github.com/thesofproject/linux/issues

Thank you very very much.

You need to call make before make bzImage.

make clean or make mrproper would perhaps help too depending how much you screwed up already.
