Comment 3 for bug 1848585

[23:45] <Cheyenne> I'm trying to perform a test build against a 5.4 mainline kernel, it appears that the Makefile is missing from the linux headers (it's a broken symlink)
[23:45] <Cheyenne> I'm pulling the linux stuff from: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4-rc3/
[23:46] <Cheyenne> (the test build is for a linux module)
[23:51] <Cheyenne> looks like I might have found a related bug: https://bugs.launchpad.net/ubuntu/+source/dpdk/+bug/1848585
[23:51] <ubot5> Launchpad bug 1848585 in dpdk (Ubuntu) "dpdk 18.11.2-4 ADT test failure with linux 5.4.0-1.2" [Undecided,Incomplete]
[23:57] <-- chrisccoulson (~chrisccou@ubuntu/member/chrisccoulson) has left this server (Ping timeout: 240 seconds).
[00:03] --> ricotz_ (~ricotz@ubuntu/member/ricotz) has joined this channel.
[00:05] <apw> Cheyenne, what packages specifically did you install
[00:06] <-- ricotz (~ricotz@ubuntu/member/ricotz) has left this server (Ping timeout: 245 seconds).
[00:13] <Cheyenne> I installed all the all.deb and amd64.deb packages from the above link
[00:13] <-- cgregan (~cgregan@ubuntu/member/cgregan) has left this server (Remote host closed the connection).
[00:14] <Cheyenne> The code I'm trying to build is a kernel module that is outside the linux tree
[00:15] <Cheyenne> (the actual failure at this point is one of the configure tests -- that tests kernel module builds)
[00:15] <-- ricotz_ (~ricotz@ubuntu/member/ricotz) has left this server (Quit: Leaving).
[00:18] <Cheyenne> (as a side note, I've successfully built my module against the current linux-5.4-rc3 from the main linux git repo)
[00:19] <Cheyenne> the problem I'm trying to resolve at the moment is one of our buildbots is failing (it's a buildbot builder that uses the ubuntu mainline kernels as a build validation test)
[00:39] <apw> Cheyenne: oh is all very small? it might be a bug i fixed this morning
[00:41] <Cheyenne> It looks like the Makefiles are missing (there are a bunch of broken links in the linux-headers directory).
[00:43] <Cheyenne> building "external" kernel modules has been an adventure with 5.4 -- there was a bug in modpost that was fixed in linux-5.4-rc3
[00:44] <apw> ahh yes that one got bit, the all package is empty
[00:44] <apw> it needs a rebuild
[00:45] <Cheyenne> Oh.. I misread your "oh is all very small".. yes it's only 2012 bytes
[00:45] <-- tcrawford (~tcrawford@209.212.58.90) has left this server (Quit: leaving).
[00:45] <apw> Cheyenne: yeah broken, i386 no longer builds which broke that all
[00:46] <Cheyenne> Ah...
[00:46] <apw> Cheyenne: resubmitted, should pop out in an hour or so, hopefully that will make it happy
[00:50] <Cheyenne> Okay... I'll watch for it and give it a try
[01:00] <Cheyenne> apw: Thanks. I'll give the build a shot after dinner.
