Plotting error caused by GKS_QT environment variable #548

Could you please try to install GR in a fresh environment and compare the installed version(s) with your current environment? |

If by fresh environment you mean creating a new environment with Here is the installed version in my default environment (@v1.10) pkg> status Plots GR
Status `~/.julia/environments/v1.10/Project.toml`
⌃ [28b8d3ca] GR v0.73.5
[91a5bcdd] Plots v1.40.4
Info Packages marked with ⌃ have new versions available and may be upgradable.And in the new environment (julia-plotting) pkg> st Plots GR

Oh, interesting, if I install julia via the julia archlinux package instead of julia-bin, GR works by default. However, this package is not recommended because it is unsupported by julia upsream (see the note here).
but copy-pasting it in the CLI now works (does nothing, does not throw an error). In both cases (installation that gives an error or not), just using the final part of the command ( |

Interestingly, we also get the error message about the missing Wayland plugin on an Arch Linux and a Debian system (with Xwayland servers), but the plot is displayed correctly in the @barche : Is the Wayland plugin automatically created for Linux targets? At least I don't see that it is explicitly disabled in the BB configuration ... |

Not able to get to a Wayland machine soon unfortunately, but can you try to add and import the |
Thanks a lot. Importing Let's see if we can automate this within GR, at least for Linux systems. For the build process, another dependency must be added for |

I don't think it is needed to add Qt6Wayland as a dependency in the build_tarballs, for QML I added if haskey(ENV, "WAYLAND_DISPLAY") || get(ENV, "XDG_SESSION_TYPE", "") == "wayland"
# loading this automatially on Wayland ensures that applications run natively on Wayland without user intervention

It worked using the juliaup AUR package! The window seems to be Wayland native (and not Xwayland), too! It does not work with julia-bin. The same error as before occurs. I will mention the issue on the AUR package in case the fix should be on the julia-bin side. Thanks a lot for the quick investigation/fix 😄 |
Hi,
I'm very new to Julia, so I'm sorry if this is something obvious.
When trying to plot (
plot(x, y)) with the GR backend, I get the error shown in detail belowClick to see error
After looking through the GR.jl code, I narrowed down the issue to the
GKS_QTenvironment variable.Before entering julia, I had not set that environment variable.
After trying to use
plot(x, y), resulting in the error above, the environment variable isOut of curiousity, I tried manually setting
GKS_QTjust the second part of that env var,/home/vandal/.julia/artifacts/2118fab1644a0abb3dd43fb741c68b42e8a92505/bin/gksqtand it worked.The line in the code that also adds
LD_LIBRARY_PATHis this one here:GR.jl/src/GR.jl
Line 358 in d919b64
I'm guessing this is something wrong with my setup, but wanted to check so I'm opening this issue. Any guidance is welcome! The fix of manually setting the environment variable on my end works, but I'm guessing this path might change with Julia version or with specific installations.
Thanks!
