Hello
I get a ton of warning while trying to install ImageView on Ubuntu 24.10 with Julia 1.11.3. At the end ImageView is not installed.

Would that help if installing in the base environment fails, considering packages there are always loaded?
@dgagnon Note that for such reasons it’s typically discouraged to install many packages in the base environment. Quoting the Pkg.jl [documentation](https://pkgdocs.julialang.org/v1/getting-started/#Getting-Started-with-Environments):
> Using only the default environment with a huge number of packages in it is a common beginners mistake in Julia.

Do you have OpenCV.jl installed in your base environment (v1.11)? As far as I can tell ImageView.jl does not depend on it, so it’s a bit weird to see it pop up here. If it is installed (and you don’t need it), try removing it and adding ImageView again.

Hello @eldee
I try to load only the packages I need. As you can see a fresh environment with `Pkg.activate(temp=true)` did not help.
I don’t use `OpenCV`, but I was looking for an alternative `heatmap()` was suggested somewhere as an alternative to `imshow()`. However I use `Images` because I need `RGB{N0f16}` in my code.
So I tried with a brand new directory:
- I created a new directory, cd there, started Julia and tried again. Same error.
- Then I tried `Pkg.rm("OpenCV")` to make sure. I was indeed removed successfully. And tried again. No mention of OpenCV anymore (good), but still the same error.
- I tried `Pkg.rm("ImageView")` and start to add it again. Same error.
I tried on my Windows laptop. The problem does not exist. however I found another problem but that will be for another post.
Reading TIFF files is also catastrophic but that will but for a third post.

The (potential) problem is that this is not really a fresh environment, in the sense that it is still built on top of the default environment, which is always loaded (in `LOAD_PATH`). (I suppose you could try `popat!(LOAD_PATH, 2)` to remove `"@v#.#"`, but I have no idea if that might actually be useful.)

I’ve checked on a pc with Ubuntu 22.04.4 and Julia 1.10.5 and encountered no issues adding ImageView.jl there. So it seems more likely to be a problem with your specific setup than Ubuntu in general.

Not sure I understand. Between every test I did today I restarted my computer. So memory was fresh. Do you mean junk files that need cleaning somewhere?

You most probably right. I simply need to know what’s wrong with my setup.
So, what’s left as a solution? Uninstall Julia and remove all files that seem related to it? I’ll try that tonight, after work.

Well, I guess my comment boils down to: what’s the output of `(@v1.11) pkg> st`? All those packages you have installed here will also be available in any other environment, including temporary ones (unless you start messing with `LOAD_PATH` etc.), because of environment stacking. Potentially you have some package which somehow interferes with ImageView.jl.
> [@dgagnon](#):
>
> So, what’s left as a solution?
As a test you could try installing Julia 1.10 via juliaup (in a (bash) terminal: `juliaup add 1.10`). Launching it with `julia +1.10` you should have a clean base environment (`@v1.10`) for which I expect `] add ImageView` to work. (I’m assuming you don’t want to keep working in 1.10, so don’t mind polluting the default environment here.) It’s not really a full solution of course, but if successful, it would show that the problem is most likely due to clashing packages.

I’d imagine that will work, but obviously comes with the downside that you have to reinstall all packages you need. But then you can directly put them into an appropriate environment 🙂 .

Packages are never automatically loaded. What is true is that the base environment is always in the load path, so you _can_ load packages from there. However, package version resolution and precompilation only takes into account the packages in the active environment, so installing in a fresh environment can indeed help in some cases where installation/precompilation in the base environment fails.

@dgagnon I can see you installed julia using juliaup. That’s great! But how did you install juliaup?

To be honest. I am not sure juliaup ever worked. I installed it after julia… And I don’t recall how.
Anyway, I removed completely julia and all directories related to it and juliaup. I reinstalled julia it at version 1.10.8 (just in case I was bleeding edge with 1.11.x).
I installed only 1 package: ImageView. It of course trigered a lot of stuff to install but at the end I got the same result.
I guess the problem is with Gtk. I have a lot of stuff called Gtk4 on my computer but I don’t know if this is related to julia or it was there before with Ubuntu.

I gizmo called “App Center”.
I am new on Linux. I used to work with Unix (SunOS, IRIX, Solaris and AIX) in my younger years. So, I don’t mind doing `find`, `grep`, `sed`, editing `/etc/fstab` that kind of stuff. But the multiple conflicting package managers (apt, App Center, snap, etc) are just confusing me.
I guess I have pretty much excluded julia as the source of my problem. Now I have to understand how Gtk works. The problem comes from a .css file missing something. I don’t even know if this stuff came with the Ubuntu distro or I installed it with the julia packages.

The general advice is to never install julia using any kind of system package manager. It’s very likely that this is your problem. Try removing julia completely and then installing it using juliaup by running the following command:
```sh
curl -fsSL https://install.julialang.org | sh
```
(Disclaimer: you should always be skeptical of copying a command from the internet and pasting it into your shell. However, if you want a “one-click” solution, this is it, as you can see for yourself here: [Download Julia](https://julialang.org/downloads/) and here: [GitHub - JuliaLang/juliaup: Julia installer and version multiplexer](https://github.com/JuliaLang/juliaup))
Once that finishes, you should be able to start julia by simply typing `julia` into the shell. Then you can try installing `ImageView` and see if anything is different.

This is elaborated on the download page ([Download Julia](https://julialang.org/downloads/#please_do_not_use_the_version_of_julia_shipped_by_linux_or_bsd_package_managers)):

Ok. I did
`curl -fsSL https://install.julialang.org | sh`
I got a new julia. And guess what? Same error while trying to install ImageView.
I tried changing the theme of Gtk to revert back to Default. It did not improve things either.
I’m on Wayland, not X11. Can that be the reason? X11 was fashionable when I was twenty-something. Now, at 63 I read that it is terrible and poorly written and other nice words that I won’t copy here.

Just as a final confirmation it would be good to check the output of `which julia` to confirm that you’re indeed using the julia executable installed by juliaup.
If this is truly related to system libraries, I’m afraid I won’t be able to help you. I thought julia was supposed to work quite independently of shared libraries when you use the official version. Hopefully someone more knowledgeable can chime in—perhaps @giordano?

Looking more closely at your original post, the final error,
```julia
symbol lookup error: /lib/x86_64-linux-gnu/libEGL_mesa.so.0: undefined symbol: wl_display_create_queue_with_name
```
does look like this could indeed be a wayland issue, given the `wl_` prefix on the symbol that’s not found.

Haven’t followed much, but what’s the output of
```julia
ENV["LD_LIBRARY_PATH"]
```
inside Julia?
