[07:28] <juergh[m]> claudio: open a ticket and provide some into to look at. Run: `ubuntu-bug linux` on that machine.
[14:49] <heeen> what are the steps to reliably build 22.10 lowlatency
[14:50] <heeen> 5.19.0-1015-lowlatency
[14:50] <heeen> I am facing various build failures following the wiki steps or other steps found on the web
[14:51] <heeen> for example, make deb-pkg gives:
[14:51] <heeen> dpkg-source: error: cannot represent change to vmlinux-gdb.py:
[14:51] <heeen> dpkg-source: error:   new version is symlink to scripts/gdb/vmlinux-gdb.py
[14:51] <heeen> dpkg-source: error:   old version is nonexistent
[14:52] <heeen> because the symlink is an absolute path and I guess it uses fakeroot internally where that path does not exist?
[14:52] <heeen> or, from LANG=C fakeroot debian/rules binary:
[14:53] <heeen> mkdir /home/florian/src-misc/linux-lowlatency-5.19.0/debian/linux-libc-dev/usr/include/x86_64-linux-gnu
[14:53] <heeen> mkdir: cannot create directory '/home/florian/src-misc/linux-lowlatency-5.19.0/debian/linux-libc-dev/usr/include/x86_64-linux-gnu': File exists
[14:53] <heeen> make: *** [debian/rules.d/2-binary-arch.mk:561: install-arch-headers] Error 1
[15:07] <heeen> also:
[15:07] <heeen> make clean
[15:07] <heeen> scripts/Makefile.clean:15: ubuntu/hio/Makefile: No such file or directory
[15:08] <juergh[m]> heeen You can't use make deb-pkg with an Ubuntu kernel. Can you list the steps from the beginning?
[15:08] <juergh[m]> heeen: ^^
[15:08] <heeen> which are the steps you suggest
[15:09] <juergh[m]> what exactly are you doing?
[15:11] <mhcerri> fakeroot debian/rules clean && dpkg-buildpackage -I -i -uc -us // maybe that instead?
[15:11] <heeen> I want to compile alsa modules and figured building the kernel would be a good precursor
[15:12] <heeen> I built the kernel before but this time something doesn't work
[15:12] <heeen> https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
[15:12] <juergh[m]> heeen: how are you doing that? how do you get the source? what commands are you running? as I said: what are your steps?
[15:13] <heeen> I'll let it run until it fails then I'll post the steps I did, hang on
[15:14] <heeen> apt-get source linux-image-unsigned-$(uname -r); cd linux-lowlatency-5.19.0/; LANG=C fakeroot debian/rules binary
[15:14] <heeen> # Install only the full versioned libcpupower.so.5.19.0-1017, not
[15:14] <heeen> # the usual symlinks to it.
[15:14] <heeen> install -m644 /home/florian/src-misc/linux-lowlatency-5.19.0/debian/build/tools-perarch/tools/power/cpupower/libcpupower.so.5.19.0-1017 \

[15:14] <heeen> make: *** [debian/rules.d/2-binary-arch.mk:775: install-perarch] Error 1
[15:15] <heeen> this is yet another way it fails now
[15:16] <heeen> ok seems like I am missing some packages
[15:17] <heeen> which are required for kenrel-tools it seems?
[15:18] <heeen> the suggested packages openjdk-8-jdk  java-1.8.0-openjdk-devel do not exist
[15:19] <heeen> trying the other command:
[15:19] <heeen> # quicker build:
[15:19] <heeen> LANG=C fakeroot debian/rules binary-headers binary-generic binary-perarch

[15:22] <heeen> juergh[m]: any suggestions?
[15:25] <juergh[m]> not today, no.
[16:01] <heeen> mhcerri: how can I make that use more cores
[16:05] <heeen> ah it seems to understand -j
[17:57] <heeen> mkdir /home/florian/src-misc/linux-lowlatency-5.19.0/debian/linux-libc-dev/usr/include/x86_64-linux-gnu

[17:58] <heeen> from mhcerri command above
[19:44] <cascardo> you should try sbuild
