Failing to precompile Plots due to LoadError

fredrikpaues · March 1, 2022, 11:59am

I’m trying to set up Julia on my work computer and encounter a LoadError when I try to precompile Plots.jl. Help would be much appreciated!

I’m on Windows 10 and use Julia 1.7.2.

Try installing ffmpeg separately on Windows and then try installing the package again. The avcodec-58.dll file is provided by ffmpeg.

fredrikpaues · March 1, 2022, 1:09pm

I have never heard of ffmpeg before this. Is this is?

giordano · March 1, 2022, 1:25pm

That won’t help anything, avcodec-58.dll is already there as clearly shown by the error message.

@fredrikpaues what version of Windows do you have? Is it by any chances one of those versions without audio/video support?

fredrikpaues · March 1, 2022, 1:38pm

I listened to Spotify through my headphones just an hour ago, so I would say no It’s Windows 10 Enterprise N LTSC version 1809.

giordano · March 1, 2022, 1:40pm

Try this:

]add https://github.com/giordano/DependencyWalker.jl
using Plots # this will result in an error, it's ok
using DependencyWalker
Library(raw"C:\Users\frpa8185\.julia\artifacts\ecb81e6429c089c1da802644fae337754832d534\bin\avcodec-58.dll")

The last command should show which library can’t be found.

fredrikpaues · March 1, 2022, 1:56pm

I hope that I did it. I’m currently on the subway running my work computer over Remote Desktop from my cell phone

I’m moderately sure that means you’re missing some Windows package to play audio/video

giordano · March 1, 2022, 2:03pm

Looks like you’re indeed in the same situation.

fredrikpaues · March 1, 2022, 9:36pm

Success! Thank you!
