swrast_dri.so missing in the `base-glibc-debian-bash` image

[kostrykin]

I have created a BioContainer using base-glibc-debian-bash as the base image: BioContainers/multi-package-containers#3817

Trying to initialize EGL within the container gives an error:

root@4e65d8c5e92a:/# python -c "import libcarna.egl; libcarna.egl.EGLContext()"
libEGL warning: 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)

libEGL warning: 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)

Traceback (most recent call last):

Indeed, swrast_dri.so is not to be found in the image:

root@4e65d8c5e92a:/# find -name 'swrast*' && echo "end of list"
end of list

From what I have found (askubuntu.com), swrast_dri.so must be provided by the libgl1-mesa-dri package, which, however, cannot be installed within the image:

root@4e65d8c5e92a:/# apt install libgl1-mesa-dri
Reading package lists... Done

Package libgl1-mesa-dri is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libgl1-mesa-dri' has no installation candidate

Can it be that swrast_dri.so is supposed to be provided by the host system? If so, how do I need to modify the Docker command line? And how can I make this work in GitHub workflow runners?

[kostrykin]

Turns out, I can install libgl1-mesa-dri via

apt update
apt install -y libgl1-mesa-dri

and then I can successfully initialize EGL inside the container.

Alternatively, I can do

apt update
apt install -y libegl1

and EGL also works fine. I think this should actually be preferred, because the libegl1 package is described as the Vendor neutral GL dispatch library (while libgl1-mesa-dri is the Mesa-specific implementation).

• Is there any specific reason, why libgl1-mesa-dri or libegl1 are not installed in the base-glibc-debian-bash image?

• Is there a different image that I can use that comes with libegl1 installed?

• Or, what's the proper approach of using EGL inside BioContainers?

[kostrykin]

I have "fixed" that by creating a custom Docker image that extends the BioContainer by installing the libegl1 apt package and the missing NVIDIA vendor file: https://github.com/kostrykin/LibCarna-Python-Docker

I'm leaving this issue as "open" because I'm wondering whether it wouldn't make more sense to provide a base image that supports EGL.
