Hello everyone

Is there a way to install the MP3 package on JuliaBox? It fails for me because I don’t have root priveleges.

Many thanks,

Lewis Hein

Hi Lewis,

I think there are two ways forwards:

1. we can add the APT packages to the JuliaBox docker image, which I think would involve adding the install to [this Dockerfile](https://github.com/JuliaCloud/JuliaBox/blob/761d39c7f8f481bdb5bf1dc4011d4e267158e551/container/interactive/Dockerfile). Doesn’t seem super sustainable though, and moves support responsibility from JuliaAudio developers to JuliaBox developers.
2. We can add support to MP3.jl to fall-back to a source build in the case where BinDeps can’t install a system package for the necessary libraries. One issue with this is that it adds time to the installation process. I don’t know enough about how JuliaBox works to know how often users need to do this. Do you get a persistent box with your packages installed, or do you have to re-install them every session?

Option 2 seems the best to me, as making the JuliaBox developers  
responsible for MP3.jl (and thereby setting a precedent for whatever  
package may have a binary dependency) would be poor organization.

I am pretty sure that my changes persist, and thus adding a one-time  
hit to build from source might not be an issue, especially if the  
alternative is not having it at all.
