I am unable to install Plots.jl on Arch Linux with julia version 1.6.2.

Output of ]status

/home/oponkork/.julia/artifacts/7f40eeb66d90d3026ae5fb68761c263b57adb840/lib/libavdevice.so should be looking for /home/oponkork/.julia/artifacts/7f40eeb66d90d3026ae5fb68761c263b57adb840/lib/libavformat.so

Something is causing libavdevice.so to load your system library rather than the one in FFMPEG_jll. Do you have a LD_LIBRARY_PATH or LD_PRELOAD in your environmental variables?

3

I do set LD_LIBRARY_PATH=/usr/lib:/usr/lib64:. How do I fix the issue?

4

Okay, I tried ENV["LD_LIBRARY_PATH"] = "" in the julia repl and then precompiled and it worked. Is this the correct approach?

5

That works, but I recommend investigating why LD_LIBRARY_PATH is set in the first place. Is it in your .bash_profile or .bashrc or something like that?

6

did you install julia via pacman? please use julia-bin from AUR or directly download binary yourself from julialang.org

7

I set it myself, do not remember why but needed it at some point in the past. Maybe I will remove it and see if anything else breaks.

8

Yes. I installed it via pacman. Is there a reason to pick up AUR package over the pacman one?

9

the reason is linux distro maintainers don’t care about Julia they only care if Julia compiles with their libraries. Better use ready-made binary Julia, either manually, or use AUR which is the same thing except it will update later.
