After you get this error, in the same session could you please run the commands

using Libdl
filter!(lib -> occursin("glib", lib), dllist())

and copy here the output?

[kennywang710]

here is output on your comment. ulia> using Libdl

julia> filter!(lib -> occursin("glib", lib),dllist()) String[]

[giordano]

Is that command run after you get the error above, in the same session? It doesn't make much sense there is no libglib loaded at all. Also, do you set any environment variable like LD_LIBRARY_PATH or LD_PRELOAD?

[kennywang710]

here is output on terminal, did you findout any information? ===terminal=== [kennyw@localhost lib64]# ls -al libglib* lrwxrwxrwx. 1 root root 23 Aug 10 23:36 libglib-2.0.so -> libglib-2.0.so.0.5600.4 lrwxrwxrwx. 1 root root 23 Aug 10 23:36 libglib-2.0.so.0 -> libglib-2.0.so.0.5600.4 -rwxr-xr-x. 1 root root 1167784 Aug 10 23:36 libglib-2.0.so.0.5600.4 lrwxrwxrwx. 1 root root 22 May 15 2019 libglibmm-2.4.so.1 -> libglibmm-2.4.so.1.3.0 -rwxr-xr-x. 1 root root 650744 May 15 2019 libglibmm-2.4.so.1.3.0 lrwxrwxrwx. 1 root root 42 May 15 2019 libglibmm_generate_extra_defs-2.4.so.1 -> libglibmm_generate_extra_defs-2.4.so.1.3.0 -rwxr-xr-x. 1 root root 261736 May 15 2019 libglibmm_generate_extra_defs-2.4.so.1.3.0 [kennyw@localhost lib64]# pwd /usr/lib64 [kennyw@localhost lib64]# echo $LD_LIBRARY_PATH /usr/lib64:/usr/local/lib:/usr/lib [kennyw@localhost lib64]#

add another information ,

julia> @show ENV["LD_LIBRARY_PATH"] ENV["LD_LIBRARY_PATH"] = "/usr/lib64:/usr/local/lib:/usr/lib" "/usr/lib64:/usr/local/lib:/usr/lib"

julia> filter!(lib -> occursin("perl", lib),dllist()) String[]

[kennywang710]

julia> @show ENV["LD_LIBRARY_PATH"] ENV["LD_LIBRARY_PATH"] = "/usr/lib64:/usr/local/lib:/usr/lib" "/usr/lib64:/usr/local/lib:/usr/lib"

[giordano]

What if you start julia with

LD_LIBRARY_PATH="" julia

so as to clear the value of the variable before starting the session?

[kennywang710]

here is output while launch julia

[giordano]

@kennywang710 I've been asking for the value of filter!(lib -> occursin("glib", lib),dllist()) after you load the package and the error. The code you've shown above is in a fresh session, that's not what I asked.

Also, please quote your code with triple backquotes

```
like this
```

Alternatively you can select the code and press the <> button in the toolbar. That'd would make your messages way more readable than what they are now.

I'll paste the answer from discourse as it is..

1. Situation: Building Plots.jl
2. Error

4. What I do
   1. Result of filter!(lib -> occursin("glib", lib),dllist()) after failing precompile

     String[]
   

   2. Result of ENV["LD_LIBRARY_PATH"] : "/home/appleparan/usr/lib:/home/appleparan/usr/lib64:/usr/local/cuda/lib:/lib:/usr/lib:/usr/lib/x86_64-linux-gnu"
   3. Result of precompile after setting ENV["LD_DEBUG"]=all : Link

Situation: Building Plots.jl

How is Plots related at all with this issue? It doesn't use Gtk.jl.

To be crystal clear, I want to see the full output of the following commands, everything run in this exact order in the same Julia session:

using Gtk # this command will fail, it's OK
using Libdl
filter!(lib -> occursin("glib", lib),dllist())

@appleparan after running the debugging commands above, what happens if you start Julia with

LD_LIBRARY_PATH="" julia

?

[appleparan]

LD_LIBRARY_PATH="" julia

This worked.

Sorry, it was my fault. I set LD_LIBRARY_PATH shell initialization files and it causes the problem. Some path in my LD_LIBRARY_PATH loads wrong glib. filter!(lib -> occursin("glib", lib),dllist()) also loads proper glib with artifact path. Thank you.

[leoTiez]

I had this issue only when using IJulia. I don't know what I did wrong. But re-installing the package and creating a new IJulia kernel did the trick. Hope that helps.

[xueminchi]

I also have the same issue. If I start julia with the command "LD_LIBRARY_PATH="" julia", the problem will be solved. However, I don't know what cause this issue, then I check the bashrc file,which contains:

export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH
export PATH="$PATH:$HOME/julia-1.6.7/bin"

Is there any conflicts or reasons that I have to start julia by "LD_LIBRARY_PATH="" julia"? When I start Julia directly without this command, I can use some packages but not the Plots package. Only when I start Julia with that command, the precompile of Plots does not trigger an issue. I tried different versions of Julia, it does not change the situation. Do you have any ideas? Thanks. @giordano
