[BUG] GKS QtTerm window does not appear with Julia v.1.8.2 on Arch Linux

[jchitpin]

Details

Arch Linux x86 platform with gr-framework installed.

I updated to Julia v.1.8.2 from v.1.6.7 (both binaries from julialang.org/) and Plots.jl with the gr() backend does not open the GKS QtTerm plotting window. Running the following codes gave no precompilation error with Plots.jl or any error in the REPL:

julia> import Pkg
julia> Pkg.add(Pkg.PackageSpec(; name="Plots", version=1.36.2)) # tested with 4 versions of Plots.jl
julia> using Plots
julia> gr()
Plots.GRBackend()
julia> Plots.plot(randn(12)) # no plot appears

I had no issues using the three other plotting backends but have not tried pyplot, inspectdr, or gaston. I rolled back Plots.jl to several older versions and reran the code above but no plotting window appeared.

The latest version of Plots.jl correctly opens the GKS QtTerm plotting window with Julia v.1.6.7.

Can your try:

$ LD_PRELOAD=$(g++ --print-file-name=libstdc++.so) julia
# or if you know the path to your `libstdc++.so`:
$ LD_PRELOAD=/usr/lib/gcc/x86_64-linux-gnu/11/libstdc++.so julia  # this is on `ubuntu 22.04`
julia> using Libdl
julia> foreach(println, Libdl.dllist())
[...]  # show us this output
julia> using Plots
julia> plot(1:2)

Apologies for taking so long to follow up. I ran the LD_PRELOAD line and the plotting window appeared!

You're probably hitting JuliaGL/GLFW.jl#198 JuliaLang/julia#34276 or similar.

Should be fixed by JuliaLang/julia#46976.

(What's the policy on necrobumping here?)

I'm seeing this again, except on top of showing no window there's also

/home/username/.julia/artifacts/13488323454a8a92411d5d627bb0f85b9b4c7006/bin/gksqt: /home/username/.julia/juliaup/julia-1.10.0-beta1+0.x64.linux.gnu/bin/../lib/julia/libcurl.so.4: version `CURL_OPENSSL_4' not found (required by /usr/lib/libproxy/libpxbackend-1.0.so)
connect: Connection refused
GKS: can't connect to GKS socket application

in the console. Same problem on +release and +alpha

$ LD_PRELOAD=$(g++ --print-file-name=libstdc++.so) julia

works fine. Apparently JuliaLang/julia#46976 didn't entirely solve it. Is there anything I can do other than creating an alias with LD_PRELOAD set?

[supertrianguloid]

I am experiencing this too on Arch. The LD_PRELOAD line works. I deleted ~/.julia/, reinstalled curl and openssl but nothing seems to fix it. Is there a way to temporarily fix it?
