Issue

It seems that Ubuntu 22.04 doesn't play well with openGL from conda-forge.

mamba create --name dev --channel conda-forge --override-channels matplotlib --yes
mamba activate dev
python -c "from matplotlib import pyplot as plt; plt.plot(range(5)); plt.show()"

libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

libGL error: failed to load driver: swrast

While the plot shows up, other hardware accelerate stuff (like using vispy) doesn't work. I didn't know where else to post this so I figured I would post it to matplotlib since it seems to have rather high visibility into these issues.

My solution was to delete the files

libstdc++.so  libstdc++.so.6  libstdc++.so.6.0.28-gdb.py  libstdc++.so.6.0.29

And let things fall back on the the libstdc++.so provided by ubuntu. seems to work :/

What version of GCC is Ubuntu 22.04 using?

It seems like it is using GLIBCXX_3.4.30 but this is the only note I can find about it: https://gcc.gnu.org/pipermail/gcc-patches/2021-April/568635.html

@hmaarrfk, can you run apt list --installed >& apt-packages.txt and attach that to this ticket? I'm trying to repro this on an Ubuntu 22.04 VM

[hmaarrfk]

apt-packages.txt Thank you for your help!

[timsnyder]

@hmaarrfk , to fully reproduce what you're seeing, I probably will need the contents of your /etc/apt/ tree. It looks like you have extra sources configured. I decided to just see if I could repro it without matching the system packages for now.

From AMI ubuntu/images-testing/hvm-ssd/ubuntu-jammy-daily-amd64-server-20220407 on AWS, I:

sudo apt update -y && sudo apt upgrade -y
sudo apt install task-xfce-desktop -y
sudo apt install tigervnc-standalone-server tigervnc-xorg-extension -y

rebooted the vm, fired up a vncserver, installed mambaforge and reran what Mark gave us in the OP for repro instructions.

I see the error message about swrast_dri.so but not the iris_dri.so. Digging into swrast_dri.so, when I run Mark's matplotlib example with LD_DEBUG=files, I see:

      3357: /home/ubuntu/mambaforge/envs/dev/lib/python3.10/site-packages/PIL/../../../././libstdc++.so.6: error: version lookup error: version `GLIBCXX_3.4.30' not found (required by /lib/x86_64-linux-gnu/libLLVM-13.so.1) (fatal)

That happens while the dynamic linker is trying to link&load /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so.

It looks like the Ubuntu 22.04 swrast_dri.so is compiled using LLVM 13 because it needs libLLVM-13.so:

[timsnyder]

I guess a good question would be why the linker isn't linking against the libLLVM-13.so we provide? I don't see libLLVM-13.so.1 being provided by the libllvm-13 conda package that I have in my dev environment:

dev) ubuntu@ip-192-168-0-41:~/mambaforge/envs/dev/lib$ conda tree whoneeds libstdcxx-ng
['numpy', 'expat', 'libvorbis', 'krb5', 'pyqtwebengine', 'icu', 'lerc', 'gstreamer', 'nss', 'libllvm13', 'libxkbcommon', 'gst-plugins-base', 'libglib', 'libtiff', 'pyqt5-sip', 'zstd', 'matplotlib-base', 'mysql-common', 'pcre', 'lz4-c', 'qt', 'pyqt-impl', 'mysql-libs', 'openjpeg', 'nspr', 'libclang', 'pyqtchart', 'kiwisolver']

['libclang']
(dev) ubuntu@ip-192-168-0-41:~/mambaforge/envs/dev/lib$ conda tree whoneeds libclang
['qt']

I'm going to go look at the clang recipes to see what's up with that.

[hmaarrfk]

It could also be a bug with ubuntu.

I'm somewhat testing out the waters before starting to install ubuntu 22.04 on all our computers. I can't seem to find much documentation on GLIBCXX_3.4.30 so maybe it isn't released yet officially?

It isn't stated in https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html and I can't find documentation from LLVM (though i'm new to using LLVM anyway).

[timsnyder]

Looks like the install-llvm.sh script might need to be tweaked at https://github.com/conda-forge/llvmdev-feedstock/blob/e779e84bfa61bf2fdf62ff3660b2dc2579ed9c53/recipe/install_llvm.sh#L16-L18

@isuruf which of our packages (if any) are supposed to be supplying the libLLVM-${VER_ARR[0]}.so.${SONAME} symlink?

It could also be a bug with ubuntu.

Maybe, but it seems like we are missing a symlink in our package.

[timsnyder]

ln -s libLLVM-13.so $CONDA_PREFIX/lib/libLLVM-13.so.1 removed the linking error for me.

[timsnyder]

It looks like Ubuntu is ending up with a different SONAME in libLLVM-13.so than we do. This is strange.

[hmaarrfk]

I haven't had a chance to read it all, but it seem quite related to: https://github.com/ValveSoftware/steam-runtime/issues/478

[timsnyder]

Ugh. I guess in their package, the debian folks have a patch that appends .1 onto the shared library SONAME https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/blob/11/debian/patches/0044-soname.diff and it looks like they have been doing this for awhile (the last edit to that patch was ~2 years ago). Looks like it was originally added in https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/commit/2009781b418f26cb44848187fa749dcde9fb0d08 and there's not really a reason given in the commit message although, looking at the details of the commit, they had been moving the library filename around to add the .1 suffix prior to that but the actual SONAME stored in the ELF didn't have the .1 suffix before that commit.

Looks like they started adding the .1 suffix to their libLLVM before they moved the package recipe into https://salsa.debian.org/pkg-llvm-team/llvm-toolchain https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=747701 is one of the earliest refrenced tickets in the git history.

So, I retract what I said about needing to tweak https://github.com/conda-forge/llvmdev-feedstock/blob/e779e84bfa61bf2fdf62ff3660b2dc2579ed9c53/recipe/install_llvm.sh#L16-L18. We aren't dropping a symlink that LLVM thinks we should have, the debian folks are imposing their own definition of SONAME on libLLVM.

[timsnyder]

I guess what ubuntu is doing isn't any worse than Centos/RHEL:

readelf -d /lib64/libLLVM-7-rhel.so

 0x000000000000000e (SONAME)             Library soname: [libLLVM-7-rhel.so]

[isuruf]

This issue is that we are not shipping libstdcxx-ng=12.0.1. PRs welcome to update the recipe to 12.0.1

[timsnyder]

Thanks for chiming in @isuruf

[timsnyder]

@isuruf, I started looking at opening a PR to update the recipe to provide libstdcxx-ng=12.0.1 but how do we do that when gcc 12 hasn't been released yet? Should we start building from the nightly snapshots? I guess that's what Ubuntu 22.04 is doing based on the version of the installed libstdc++6 I have:

libstdc++6/jammy,now 12-20220319-1ubuntu1 amd64 [installed,automatic]

I'll create a PR that targets the rc channel with the latest snapshot of gcc12 branch.

[isuruf]

Ah. Never mind then. @hmaarrfk, your only option is to delete $PREFIX/lib/libstdc++* as you did.

[timsnyder]

And I guess after looking at https://conda-forge.org/docs/maintainer/knowledge_base.html#pre-release-version-sorting again that I should name the version 12.0.1dev20220403? Seems a little strange that Ubuntu is shipping pre-release libstdc++ in 22.04 given that gcc 12 won't release before 22.04 comes out of beta.

[timsnyder]

Yeah, looking at what it would take to create a dev version of the ctng_compilers_feedstock, I'd rather hold off until gcc12 is released in a few months...

[hmaarrfk]

hmm. Ok.

I understand and likely agree that I jumped the boat too early.

Would a solution for me be to: libstdcxx-ng version 12.0.1 that doesn't provide any files at all but depends on __glibc=2.35=0?

[isuruf]

__glibc=2.35.0 doesn't guarantee that libstdcxx-ng is 12

[hmaarrfk]

Can i maybe depend on the user_agent?

             user-agent : conda/4.12.0 requests/2.27.1 CPython/3.9.12 Linux/5.15.0-25-generic ubuntu/22.04 glibc/2.35

[isuruf]

Not at the moment.

[isuruf]

You can create an empty libstdcxx-ng locally and use that locally.

[hmaarrfk]

Thank you all for your help troubleshooting this.

I'm not sure if we will be able to miss this bug. I think many people will install ubuntu 22.04 in late april.

Well given the constraints of time, our desired effort to support experimental gcc, I'm going to upload my own libstdcxx-ng to my channel.

Users that want that can copy the file can do so from https://anaconda.org/mark.harfouche/libstdcxx-ng

It was generated with the following meta ```yaml package: name: libstdcxx-ng version: 12.0.1+ubuntu2204 build: number: 0 skip: True # [not linux] requirements: host: - __glibc=2.35=0 about: summary: Dummy files for libstdc++ for compatibility with Ubuntu 22.04 extra: recipe-maintainers: - hmaarrfk ``` Then ran with: ``` conda mambabuild . ```

[isuruf]

gcc 12 will be released in late April, so we can just wait.

[isuruf]

There's a release candidate now. https://gcc.gnu.org/pub/gcc/snapshots/12.1.0-RC-20220429

[traversaro]

xref: conda-forge/matplotlib-feedstock#318

My solution was to delete the files

libstdc++.so  libstdc++.so.6  libstdc++.so.6.0.28-gdb.py  libstdc++.so.6.0.29

And let things fall back on the the libstdc++.so provided by ubuntu. seems to work :/

An alternative workaround (perhaps less invasive) that we used in https://github.com/RoboStack/ros-galactic/issues/101 is just to use LD_PRELOAD:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 ros2 run rviz2 rviz2

for us it is working, not sure anyhow if it covers all the possible use cases.

[isuruf]

gcc 12.1 is released now. PRs welcome

[OlivierMiriel]

May the issue still be on Ubuntu 22.04 ? I just install and can't run gmsh. Only doing ' sudo gmsh' can launch gmsh. If I try 'gmsh' alone in the command line then I get the following error:

libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast
XRequest.151: BadMatch (invalid parameter attributes) 0x0
Segmentation fault

how to solve this ? do I need to go back to Ubuntu 20.04 ? thanks

[traversaro]

@OlivierMiriel can you post you environment (i.e. the output of conda list?)

[ShantanuKodgirwar]

I am also facing the same issue. In fact, I read this thread and forcefully bumped up the gcc to 12.0.1 (Ubuntu 22.04 ships with 11.2.0). It did not fix it.

Would reinstalling 22.04 instead of updating to 22.04 from 20.04 help?

[traversaro]

@ShantanuKodgirwar can you post your environment (i.e. the output of conda list?) and your exact error? Thanks!

[ShantanuKodgirwar]

Sure. Although I am actually using a poetry virtual environment. So I'll give that list.

First of all the error message which is really same as OP.

libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

libGL error: failed to load driver: swrast

Here is the result of pip list in my virtual env.

[traversaro]

Sure. Although I am actually using a poetry virtual environment. So I'll give that list.

If you are using poetry, I doubt the problem is related to what is discussed here. In the issue discussed here, the libstdc++.so provided by conda-forge is used in place of the one provided by the system, but the system OpenGL driver required some symbols that were specific of GCC 12 (the version used by the system libstdc++.so), so the loading failed. Updating the conda-forge's libstdc++.so to GCC 12 provide all symbols required by the system OpenGL driver solved the issue. However, if you are not using conda-forge, the problem that you are experiencing is not related.

If you want to debug your problem, I suggest to run your code with LIBGL_DEBUG=verbose as done in https://github.com/RoboStack/ros-galactic/issues/101#issuecomment-1118735174 . However, I would kindly ask you to track your problem somewhere else, as it is not related to conda-forge, thanks!

[ShantanuKodgirwar]

I swapped up the environment with a conda environment and I face the same error.

[traversaro]

I swapped up the environment with a conda environment and I face the same error.

Then can you provide the conda list and the output of LIBGL_DEBUG=verbose commandthatiscreatingtheproblem?

[ShantanuKodgirwar]

I am sorry. I am not well versed with libGL. I tried to write LIBGL_DEBUG=verbose in terminal before running the file (also after), didn't result in anything other than the below error that is generated every time I run my file.

libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast

The output of conda list is

You need to write LIBGL_DEBUG=verbose right before the command that you are launching, not before. If you speficy the command that is giving you problems, I can show.

Ahhh. Gotcha. :)

The relevant message is:

From the version numbers, I guess you are using the default channels, instead of the conda-forge channel? To benefit from the fix discussed here, you should switch to use the conda-forge channel, for example passing -c conda-forge when you create the environemnt. Apparently issue described in this issue was not solved in the default channel.

I have the same issue just trying to plot with matplotlib on a Windows 11, WSL2 installed Python:

import numpy as np
import matplotlib.pyplot as plt

print("run")
print("before figure")
plt.figure()
print("begin")
xs = np.arange(0,10, .1)
plt.plot(xs, np.sin(xs))
print("middle")
print("goodbye")
plt.show()

And I get the error message:

libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast

As mentioned in https://github.com/conda-forge/ctng-compilers-feedstock/issues/95#issuecomment-1241891097 can you post the output of conda list, the output of conda info, the Linux distro you are using and the output of the command that is giving you the error after setting LIBGL_DEBUG to 1?

@homerobse, you are not using conda-forge. Please open an issue with anaconda where you get the packages.

[homerobse]

Thanks for looking into it. Can you give me a little more detail of how to fix it? What exactly should I change to be using conda-forge and how can I do that? This error happens both in my base conda environment and in others.
