Description peteru 2019-08-17 11:00:19 UTC
This looks like a compatibility issue with kernel 5.2 as documented here:

https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket
We need to have all information at hand before ticket assignment, so that the maintainer can look after it in one session with minimal number of callbacks.
Please reopen this ticket (Status:unconfirmed) afterwards.

Comment 5 peteru 2019-08-17 13:39:19 UTC
I appreciate that you want to follow the documented bureaucratic process. Full log attached as requested.

However, I think you will find that the relevant excerpt and information I provided in previous comments is sufficient to make progress.

The fault boils down to the need to

 #include <linux/sockios.h>

in

 third_party/webrtc/rtc_base/rtc_base_generic/physicalsocketserver.cc

with kernel 5.2 and newer.

And as always, thanks to all Gentoo developers. You guys and girls make Linux cool. ;-)

To be precise the directory (with emerge/ebuild) is:

portage/dev-qt/qtwebengine-5.12.4/work/qtwebengine-everywhere-src-5.12.4/src/3rdparty/chromium/third_party/webrtc/rtc_base

And the suggested patch from the Qt link peteru provided is attached.  I have not tested it yet.

See https://bugreports.qt.io/browse/QTBUG-76963 for the original report and https://bugreports.qt.io/browse/QTBUG-76963 for the report of this instance.  The attachment is the patch from the latter up-stream bug with the file name of the file in question adjusted for the Gentoo qtwebengine-5.12.4 build (removing the underscores).

Place the attached file in the (new) directory:

/etc/portage/patches/dev-qt/qtwebengine-5.12.4/

and execute "emerge --oneshot qtwebengine", then wait a while; the build succeeds.
Comment 9 Paul Preney 2019-08-18 06:16:26 UTC
An FYI: qtwebengine 5.12.4 failed to compile on my system (with the same error as the original post) but the last patch worked on my two systems.

I am posting this due to earlier mentions in comments: that I am running Linux kernel 5.1.15 --not v5.2-- and the issue of not being able to build qtwebengine also occurred.

I think the patch should point to physicalsocketserver.cc, not physical_socket_server.cc
Comment 11 John Bowler 2019-08-18 15:06:02 UTC
From peteru's original report:

sys-kernel/linux-headers: 5.2::gentoo (virtual/os-headers)
sys-libs/glibc:           2.29-r4::gentoo

I believe the problem arose as a result of one of those changes, most probably the first.  To test your system:

equery l linux-headers glibc

IIRC linux-headers updates independently of the actual kernel, after all you can have multiple kernels installed but only one linux-headers.
Comment 12 Paul Preney 2019-08-18 16:59:37 UTC
FYI running "equery l linux-headers glibc" on my systems that the patched qtwebengine builds and installs yield:

$ equery l linux-headers glibc
 * Searching for linux-headers ...
[IP-] [  ] sys-kernel/linux-headers-5.2:0

 * Searching for glibc ...
[IP-] [  ] sys-libs/glibc-2.29-r4:2.2

however know "uname -r" yields:

$ uname -r
5.1.15-gentoo

The latter is the version of the kernel you are running, which depends on the kernel image loaded at system boot via the boot loader.  It won't change until you both have a different version built and installed and select it on reboot.  The equery output refers to the files installed in the root file system and these change on emerge.  linux-headers provides the <linux/...> files and that seems to be where the relevant change was made.

A possible work round, other than the patch (which seems harmless) is to downgrade linux-headers to linux-headers-5.1, either by forcing emerge to do it (emerge =sys-kernel/linux-headers-5.1) or by masking =sys-kernel/linux-headers-5.2 in /etc/portage/package.mask.  I haven't tried either.
Comment 14 Paul Preney 2019-08-19 19:51:39 UTC
Heads-up that this issue is possibly more major...

On my two systems that I applied the patch after rebooting KDE has no sound (the multimedia System Settings module says, "The module Multimedia is not a valid configuration module." Nothing else appears therein.)

So I masked sys-kernel/linux-headers:5.2 to install v5.1, moved the patch out, and I am currently rebuilding qtwebengine (which will take hours) to see if my multimedia comes back (it should as this was the only config item that changed on these systems between reboots). If it doesn't come back then I will try masking qtwebengine 5.12.4 and start reverting to older previously installed packages until things work again.
Comment 15 Paul Preney 2019-08-20 05:44:13 UTC
WRT Comment 14:

Masking sys-kernel/linux-headers-5.2 and then
emerge -1v sys-kernel/linux-header
(or if preferred: emerge -1v =sys-kernel/linux-headers-5.1)

followed by:

  emerge -1v =dev-qt/qtwebengine-5.12.4

works without the patch from this issue.

So, either the patch is used, or, one avoids upgrading linux-headers to v5.2.

---

With respect to my multimedia issues mention in Comment 14, they appear to have been fixed and the problem was not due to qtwebengine so such is not relevant to this issue.
Comment 16 Geoff Madden 2019-08-24 07:30:03 UTC
tried the above patch ,did not take,manually inserted ,repacked file then i get
failure of the nouveau patch,I assume it was because of the differing file size
I had repacked as a tar.xz file as original but the oneliner installed created
a sustatially larger filemwhich I duly inserted in distfiles reran ebuild on 
/usr/portage/dev-qt/qtwebkit/*.5.12.4.  Some help here is needed as i suspect the rest of the patches
will fail as well.

@Geoff

Try discarding your custom modifications to the distfile and to the ebuild and do the following instead:

# mkdir -p /etc/portage/patches/dev-qt/qtwebengine-5.12.4
# cd /etc/portage/patches/dev-qt/qtwebengine-5.12.4
# wget "https://692352.bugs.gentoo.org/attachment.cgi?id=587222" -O 0001-fix-build-after-y2038-changes-in-glibc.patch

>Created attachment 587962 [details]
<point of failure after applyting sockios.h patch

That's not the point of failure because of:

MAKEOPTS="-j5"

see your emerge info.  The real point of failure is some unknown number of lines before the ones you reported, you can either track back up from the ninja message to find the error (I just search for "error", but then I use MAKEOPTS="--jobs" :-), or you can do this:

MAKEOPTS="-j1" emerge --oneshot dev-qt/qtwebengine

Sounds like there is some interaction with the other changes you are making, the easy way out is to mask the 5.2 headers; you are using the 5.1 kernel so don't need them.

Which is effectively the same patch that John Bowler provided earlier.

The patch from John Bowler works. It should be added to the ebuild and released so that this bug can be closed.
Comment 26 Robert Crawford 2019-08-26 14:52:57 UTC
I applied the linux-headers-5.2 patch described in comment 23.
qtwebengine-5.12.4 now compiles OK. Also, enabled the jumbo-build USE flag, which cut compile time by 2/3. Amazing!

However, the final compile output "severe warnings" posted below seems a bit upsetting. Could this have anything to do with jumbo-build, and/or the linux-headers-5.2 patch, or neither, and is it cause for concern at all?
Any thoughts on this situation?

I had these warnings the last time I was able to compile qtwebengine.
Comment 28 peteru 2019-08-26 17:07:32 UTC
Those warnings are unrelated to the patch or USE flags.
Comment 29 Geoff Madden 2019-08-28 10:58:44 UTC
Regarding my point of failure 587962 Iwas led up a path, once I had corrected
my mistakes,I manually reapplied the patch again, and modified the ebuild to the
2nd makeopts changed from 0 to 1 the file is now compiling well into 13000 bracket area 
now, if any one is still having hassles I suggest this extra small change
will be helpful

Comment 35 LW 2019-09-29 22:27:20 UTC
Should dev-qt/qtwebengine-5.12.3 somehow enforce a dependency on <=linux-headers-5.1? I upgraded the kernel to 5.3.1 and headers to 5.3 and then qtwebengine-5.12.3 wouldn't build.

An upgrade of all dev-qt packages to 5.12.5 gets past the SIOCGSTAMP issue. Still waiting for qtwebengine's rebuild to complete.
