[SOLVED] llvm-runtimes/libunwind vs. sys-libs/libunwind

First time trying to build a complete system with the LLVM/clang profile (default/linux/amd64/23.0/llvm/systemd). I've been successful in building a console-only systemd-based system, but I'm running into a road block when trying to finish up my Cinnamon install. Here's what I've done so far:

--> Cloned my working console system
--> Created a local profile for system

Code: Select all

/var/db/repos/local/profiles/llvm-cinnamon/eapi
8

/var/db/repos/local/profiles/llvm-cinnamon/parent
gentoo:default/linux/amd64/23.0/llvm
gentoo:targets/desktop/gnome
gentoo:targets/systemd

--> USE="alsa dbus dist-kernel llvm-libunwind networkmanager pulseaudio python3_12 ssh systemd uefi X -ipv6 -bluetooth -gnome-online-accounts -webengine"
--> updated @world
--> installed Cinnamon and lightdm

Code: Select all

sudo emerge -avk gnome-extra/cinnamon x11-misc/lightdm
sudo systemctl enable lightdm.service

After rebooting, my system was running as expected. Now I run into the libunwind problem, due to the package dev-util/sysprof bringing in sys-libs/libunwind:

Code: Select all

sudo emerge -avk x11-terms/gnome-terminal gnome-extra/{gnome-calculator,gnome-system-monitor} media-gfx/{gnome-screenshot,eog} \
          app-text/evince app-arch/file-roller app-editors/gedit

I've narrowed this down to gnome-terminal, but since I'm trying to build a standard Cinnamon system, I wanted to stick with its default terminal program. Plus, I'm not convinced that this won't happen again with another package in the future.

What do I need to do to rectify this?

Try

Code: Select all

USE="-unwind" emerge -1av =dev-util/sysprof-3.48.0

then run your gnome emerge.
If it works mask

Code: Select all

>dev-util/sysprof-3.48.0

and create a package.use file

Code: Select all

=dev-util/sysprof-3.48.0  -unwind

It is a patch but you will run again to same problem in future.
If you are really desperate later on you can try

Code: Select all

echo "dev-util/sysprof-46.0"  >>  /etc/portage/profile/package.provided

It is a dirty trick that may create runtime problems for sysprof.But you can try it as a last resort.
Best if you DIDNT.
Also since you have llvm-libunwind maybe use a universal USE="-unwind" in make.conf.

Thanks so much for the detailed reply. I have a couple of concerns before I proceed:

1) sysprof-common has already been installed with version 46; should I rebuild it with the 3.48 version to match sysprof?
2) I tried adding USE flags, both globally and per the sysprof package, and they were ignored (at least with the failing 46.0 version)
3) Since you're suggestion is implicating gtk4 as a possible problem, could this explain why I can't build open-vm-tools (tons of failures with Gtk/Gdk, does not fail on gcc-profile systems)

1) sysprof-common has already been installed with version 46; should I rebuild it with the 3.48 version to match sysprof?

What happens if you run

Code: Select all

USE="-unwind" emerge -1av =dev-util/sysprof-3.48.0  sysprof-common

does it let you?

2) I tried adding USE flags, both globally and per the sysprof package, and they were ignored (at least with the failing 46.0 version)

Yes because the sysprof-46.0 version no longer has an "unwind" USE flag.
if the above fails,
what happens if you do the package.provided dirty trick?

Do you need dev-util/sysprof installed? You said you narrowed it down to gnome-terminal, but from a quick look at that package, I do not see why it would need sysprof. As of my last sync, every use of that package is guarded by a USE flag, so if you USE=-sysprof everywhere, you should be able to avoid installing dev-util/sysprof.

Yeah, I saw that myself. There's some package that gnome-terminal requires that also requires sysprof. I will give your suggestion a try - thanks!

I'm hoping to avoid that, but I'll have to try it if the other suggestions don't work.

Thank you everyone - I'm finally past this hurdle. Adding "-sysprof -unwind" did the trick. I'm not certain as to why sysprof is a dependency of so many packages. On my main Arch rig, it's not installed at all.

Now, for the final piece to the puzzle...open-vm-tools!

bstaletic · Post by **bstaletic** » Wed Dec 25, 2024 6:10 am

Looking at all the ebuilds that depend on sysprof, I can see that not all of them use sysprof? ( dev-util/sysprof ).
More specifically, elfutils is the only thing that uses USE=stacktrace to pull in sysprof.

Given what the sysprof dependency is used for, this might be a good thing (tm), but it was a bit of a "huh" moment.
