Deepin and LTO

[glitchking007]

Is anyone currently running the Deepin Desktop Environment with the default overlay CFLAGS? I'm about to start bringing my fresh install up to the safe CFLAGS then get more aggressive and try to bring it up to -Ofast. Was wondering if anyone has tried getting deepin working?

[javashin]

im going to install DDe today i will share

[javashin]

hmm looks like im gonna pass

deppin pkgs wants me to downgrade qt pkgs and enable gles2 for qt

@glitchking007 I'm assuming you're using deepin-overlay? I'll test it out when I get a chance.

[glitchking007]

Yes I'm using deepin-overly I switched to using -03 and lto + graphite from just ,-O2. control center worked on -02 after switching it segfaults when I try opening it

[javashin]

well i figured out now no gles2 and no downgrade of qt im emerging now .

[javashin]

well so far media-gfx/byzanz cant campile here
(media-gfx/deepin-screen-recorder-2.8.0:0/0::deepin, ebuild scheduled for merge) requires media-gfx/byzanz, media-gfx/byzanz (dde-extra/dde-meta-multimedia-0.2-r1:0/0::deepin, ebuild scheduled for merge) requires media-gfx/deepin-screen-recorder (dde-base/dde-meta-15.10.1:0/0::deepin, ebuild scheduled for merge) requires dde-extra/dde-meta-multimedia

@glitchking007 do you enabled multimedia ? and emerged those two pkgs ? byzanz and deepin-screen-recorder?

EDIT: ok disabling gif media-gfx/deepin-screen-recorder -gif drops byzanz dep

[glitchking007]

Im using the 17.1 desktop profile with the deepin-overlay I and using kwin and have ~amd64 set globaly. I am not using multimedia right now.

[javashin]

other pkg failed too dde-base/dtkwidget-2.0.14::deepin

[javashin]

@glitchking007 what Qt Version ? i have 5.13.0 here

[javashin]

ok i found afix for dde-base/dtkwidge and qt 5.13.0

[javashin]

uff is taking long than i though i have to fix a lot of ebuilds and deps of deepin to build with new Qt 5.13 and a lot of manually "ebuild * unpack configure compile install qmerge" merges jejeje but for what deepin is a nice mixed qt/gtk desktop , made with GO. never care about deepin but i watched a video on youtube about the top 5 linux desktop and i tried elementary os livecd and was not very good to me this pantheon , so the next one was deepin i downloaded the wrong iso the installer one and i booted from my usb pendrive and i was not going to install it so i booted it on virtualbox and i installed it there and was too slow and based on ubuntu lts with old kernel so i deleted and i saw this issue before about deepin and want to know if i can get it working on my gentoo lto :>

[InBetweenNames]

Interesting that the control center segfaults. Are you familiar enough with gdb to get a stacktrace of where the segfault happens?

[glitchking007]

I haven't used it before but I tried to use it. But it complained about no debugging symbols.

[javashin]

deepin-movie-reborn fails with lto + ld.gold , and qtnetwork 5.13.0 , fails with no lto and ld.bfd but seems related to qtnetwork 5.13.0

[javashin]

wow what a mess i finally emerged all the deepin stuff , i can confirm deepin-control-center segfaults , also dde-dock , i have no desktop either everything is broken , just deepin-music and deepin-movie and deepin-mutter or deepin-metacity i dont know but i got window manager composited and no screen tearing . well im recompiling some core deps with no lto to see if i get a working desktop

[javashin]

yes dde-file-manager works fine now compiled with no lto

[javashin]

media-gfx/deepin-image-viewer segfaults too , by the way everything here was compiled with lto all the deepin-stuff and seems like removing lto from those deepin pkgs which are segfaulting gets fixed doing that

[javashin]

media-gfx/deepin-image-viewer fixed too with no lto

[javashin]

hmm deepin-control-center and dde-dock needs more than eliminating lto to stop segfault im trying with sane cflags now

[javashin]

@glitchking007 have u checked the dmesg when deepin-control-center segfault and dde-dock too

here segfault because of qtmultimedia

[javashin]

good after rebuild qtmultimedia with no lto dde-dock dont segfault anymore and deepin-control center either

[javashin]

no segfaults with

[javashin]

i tried to recompile back deepin-image-viewer with lto and segfaults again

[glitchking007]

I'm running qt version 5.12. I don't much experience with debugging trying to learn. I have not checked the dmesg. I haven't had time the last 2 days

[javashin]

well i got working deepin desktop with no segfaults -O3 as default and every thing lto with some exeptions

deepin-dock and deepin-control-center compiles fine with lto nd works fine the two after re-emerge QtMultimedia with no-lto @glitchking007 try rebuild qtmultimedia without lto and problem fixed

[javashin]

well i cant change the fonts on deepin-control-center maybe its related to lto who knows

EDIT: no problems with lto , noto-fonts was missing

[glitchking007]

Ok thank you I will try it out when I get some time

[javashin]

Nice Desktop Compiled With LTO , Compatible With GentooLTO Certified , lol

[javashin]

this issue can be closed since there is nothing wrong on building deepin with LTO with the exption of deepin-image-viewer and deepin-file-manager needs to be compiled without LTO to not segfault

better open a issue about QtMultimedia Compiled With LTO That Causes dde-dock to segfault and dde-control-center :) cheers and happy compiling.

[javashin]

well there is other pkg that not support LTO if compiled deepin-toolbar with llto the settings dont works \ without lto works fine
