Error: GKS: can't connect to GKS socket application

[programistawpf]

Win7 64 SP2,
Completly new instalation of Julia and GR (gksqt.exe), after clean disk. Added only (and depended) one pacakges Plots. The error is sometimes with this seme data and code ! I.e. In the same loop somtimes is sometimes no !

Have you solved it now?

[mkborregaard]

I have a feeling this is a GR issue, not plots. What happens if you open a fresh session and do using GR? What if you try plotting with GR?

[programistawpf]

No, on new isntal Julia 0.6.2 on Win7 64 is stiil the same error. Paul W dniu 2018-08-23 o 19:30, Ding pisze:

[aramirezreyes]

Have the same error on Linux64, is there any update on this?

[cmcaine]

@aramirezreyes I had a similar issue on Linux and just had to install qt4. Are you sure you've got libQtGui?

[aramirezreyes]

@cmcaine Yes, I have it. It is some weird behavior that sometimes appear but sometimes no. I will try to find the minimum conditions to reproduce it.

[heitorPB]

I have the same problem in ArchLinux. The problem is a missing library:

$ cd  ~/.julia/packages/GR/IVBgs/deps/gr/bin
$ ldd gksqt 
	linux-vdso.so.1 (0x00007ffffe1eb000)
	libQtGui.so.4 => not found

Similar warning show up for Julia 1.1.0
when a sequence of plots (around 1e5 plots) are saved, after some time firewall prompt shows up and ask for permission for gksqt to get online.

The plots can be saved then with a relatively slow speed.
and the warning shows:

GKS: Open failed in routine OPEN_WS
GKS: GKS not in proper state. GKS must be either in the state WSOP or WSAC in routine ACTIVATE_WS
connect: No error
GKS: can't connect to GKS socket application
Did you start 'gksqt'?

GKS: Open failed in routine OPEN_WS
GKS: GKS not in proper state. GKS must be either in the state WSOP or WSAC in routine ACTIVATE_WS

However if a relatively smaller quantity of plots are saved (less than around 1e4 plots) then this warning would not show up

[dnabanita7]

I am getting the similar issue along with added errors which I have mentioned below.

connect: Connection refused
GKS: can't connect to GKS socket application

On win7 64, Julia 0.7 at this moment some time is still. I have only 1 version julia on my WIN7 profile , and after run manualy gksqt.exe sometime i have something like:

Same problem:
Julia 1.3.1, Ubuntu 19.10:

(v1.3) pkg> st Plots
    Status `~/.julia/environments/v1.3/Project.toml`
  [28b8d3ca] GR v0.46.0
  [91a5bcdd] Plots v0.29.2

Tried to update to GR 0.47.0, but plots didn't like that (as in didn't allow to update because of version bounds)
@jheinen, any idea?

[programistawpf]

Yes, a seen it.
For WIN : gksqt.exe a set shortcut to this into \Startup (AUTOSTART)
localization in RUN: shell:common startup
It HELP :)

[SimonDanisch]

Seems one needs to install additional dependencies on linux:
https://gr-framework.org/julia.html#installation
Would be nice to have these instructions in an error if those libraries aren't found!

[programistawpf]

MAybe this test some help?

Some ideas?
Now, I heve gksqt.exe in Autostar of WIN and Plots works.

[jheinen]

I'd recommend to switch to a 1.x version. With GR we already support 2 dozen platforms, but there are personal and technical (CI/CD) limits somewhere.
