lubot<tsimonq2> @mitya57 Did you want to do something about QtWebEngine or should I?08:24
lubot<mitya57> @tsimonq2, I donโ€™t know a solution. But you can try of course, maybe what Lazy suggested.09:39
lubot<tsimonq2> Fwd from mitya57: Ok, so our options are:09:39
lubot- try --no-parallel / -j109:39
lubot- force another compiler (older gcc?)09:39
lubot- try with different compiler options09:39
lubot- ask doko or on ubuntu-devel@09:39
lubot<tsimonq2> Is this still valid?09:39
lubot<mitya57> Still valid, but no promise it will work :)09:40
lubot<acheronuk> @mitya57, RPL_CONSUMER_TYPE_ERASED_ALWAYS ?09:47
lubot<mitya57> This is what he suggested, but I never used that.10:00
lubot<tsimonq2> I'll upload with `--no-parallel`10:00
lubot<acheronuk> @tsimonq2, that will finish building on ummmmm..... Friday?10:14
lubot<acheronuk> :P10:14
lubot<tsimonq2> @acheronuk, Tuesday LO10:15
lubot<tsimonq2> *:P10:15
lubot<acheronuk> I vaguely recall launchpad killing webengine builds that used โ€”no-parallel as it thought builds had stalled?10:16
lubot<acheronuk> maybe I misremember, or that was fixed10:17
lubot<tsimonq2> Just poked in #launchpad10:17
lubot<acheronuk> I wasn't total time if I recall, but that with only one process, certain parts of the build went so long between output, that LP thought the build had died10:18
lubot<mitya57> @acheronuk, Yes, it was fixed in https://launchpad.net/ubuntu/+source/qtwebengine-opensource-src/5.9.5+dfsg-0ubuntu210:26
lubot<acheronuk> @mitya57, ๐Ÿ‘10:27
lubot<acheronuk> @tsimonq2, failed with same error15:34
lubot@mitya5715:34
lubot<mitya57> ๐Ÿ˜•15:48
lubot<acheronuk> @mitya57, odd. build times for amd64 and i386 were quicker, and the arm64 failure came around the same build time (in relative terms), so I wonder if the change Simon did actually had the intened effect?15:52
lubot<acheronuk> I have no experiance with builds that use ninja, so I shrug15:54
lubot<mitya57> There are 5 commands printed after the failed one, so it is still parallel16:06
lubot<mitya57> Looks like ninja defaults to parallel, so you need to pass -j1 explicitly to it.16:07
lubot<acheronuk> @mitya57, in export NINJAFLAGS ?16:18
lubot<mitya57> Is there such a variable?16:20
lubot<acheronuk> @mitya57, that seems to think so? https://salsa.debian.org/qt-kde-team/qt/qtwebengine/blob/experimental/debian/rules#L616:21
lubot<mitya57> Oh, right, it is understood not by ninja itself but by `src/core/gn_run.pro` which adds them to ninja commandline16:21
lubot<mitya57> So `export NINJAFLAGS=-v -j1` will make the build non-parallel, but there is still no promise that it helps.16:22
lubot<tsimonq2> @mitya57, Can one of you do it? :)20:03
lubot<tsimonq2> (I ask because the earliest I can is in six hours...)20:07
