Could not load library "libGR.dll" #1720

orswan · 2018-09-05T06:12:08Z

Something has broken in GR:

julia> using Plots

julia> plot([1:10;])
ERROR: error compiling _plot!: error compiling _display: could not load library "libGR.dll"
The specified module could not be found.

Stacktrace:

I've successfully used GR recently, but something apparently broke when I tried to install Plotly. The installation of Plotly failed, and now I can't use GR either. Any tips on fixing this problem?

Please try:

ENV["GRDIR"]=""
Pkg.build("GR")

Had the same problem under linux:

julia> plot(rand(100))
ERROR: error compiling _plot!: error compiling _display: could not load library "libGR.so"
libGR.so: Kann die Shared-Object-Datei nicht öffnen: Datei oder Verzeichnis nicht gefunden

Building the GR package again helped (here in the pkg console - type ] in julia>):

(v0.7) pkg> build GR
  Building GR → `~/.julia/packages/GR/ztzRc/deps/build.log`

Loading Plots.jl again sets the environment variable...

julia> using Plots

jheinen · 2018-09-06T07:11:40Z

@orswan : Did the package build solve the problem?

orswan · 2018-09-06T07:25:43Z

Actually, before you suggested it, I just did a total reinstall of Julia, including deleting ~/.julia. So I'm afraid I don't know whether your solution would have worked. Sorry!

daniepf · 2018-09-06T15:51:20Z

@jheinen
I had the same problem which has been solved by your fix, thanks.

Please try:

Pkg.build("GR")

This worked for me on Windows. Had to restart julia to get the re-build to take effect, but it works.

tallakt · 2019-01-23T14:47:21Z

FWIW rebuilding worked for me in OSX

JeffFessler · 2019-04-30T10:52:42Z

On Mac OSX 10.11.6 with Plots v0.24.0 and Julia 1.1.0 I just got the error

ERROR: error compiling _plot!: error compiling _display: could not load library "libGR.so"
dlopen(libGR.so.dylib, 1): image not found

and ]build GR solved it for me too.

jasonsychau · 2019-07-31T05:15:53Z

My Plots package was working, but it was suddenly not. I started using Plots with a pyplot backend, so I tried using the pyplot backend (pyplot() after using Plots) then restarted my notebook without pyplot to fix the problem.

jbseby · 2019-08-04T21:24:31Z

I have the same problem when using Plots.
I tried the same solution proposed by jheinen and metanoid, i.e.

ENV["GRDIR"]=""
Pkg.build("GR")

but I receive the following message error:

Please try to ] update and/or remove anything under ENV["GRDIR"] and joinpath(ENV["GRDIR"], "../downloads") and restart julia.

Yes, it works! Thank you very much, that's really helpful.

I tried
ENV["GRDIR"]=""
Pkg.build("GR") , this did not solve my problem.
Julia 1.5, I have Tried with Julia 1.4 and 1.5. same problem.

jheinen · 2020-08-11T04:21:18Z

Did you ] up GR before building it?

hafez-ahmad · 2020-08-11T08:53:00Z

I tried to build, but it is taking forever.I used GR backend plot with earlier version . But don’t what's going on my laptop.today I deleted completely then reinstalled julia 1.5 then it worked fine.

Renmusxd · 2023-10-12T17:38:24Z

Hi, I ran into this issue myself with a fresh julia 1.9.3 install on a new macOS 13.4 system.
After add Plots worked, attempting to run plot(1:10) left me with a could not load library libGR.so.

The environment variable pointed to a directory ~/.julia/packages/GR/BwGt2/src/../deps/gr/lib which contained libGR.dylib. Simply symlinking ln -s libGR.dylib libGR.so.dylib solved the problem, but this is obviously a hack. Is there a better option?

jheinen · 2023-10-13T07:48:12Z

Was there an old GR installation? Did you ] up GR (or better all packages)?

Renmusxd · 2023-10-13T14:09:21Z

This was completely fresh - this is my first time using Julia so nothing Julia related was on the computer until installed Julia, then added ITensors and Plots.

In case ITensors was the issue I removed it, and installed Plots by itself with the same result.

jheinen · 2023-10-13T14:57:49Z

Could you please try to install GR v0.72.10 in an empty environment and start julia with JULIA_DEBUG=GR? I have absolutely no idea what causes the problem(s).

rename or remove ~/.julia
JULIA_DEBUG=GR julia
] add GR
surface(peaks())

Renmusxd · 2023-10-16T15:05:47Z

Thanks, I deleted .julia as well as all the julia related files from my system, then reinstalled everything from scratch. I've been so far unable to recreate the bug. The first iteration must have been misconfigured somehow, or else I missed something. Sorry about the false alarm, and thanks for this project!

Doublonmousse · 2023-11-04T11:30:36Z

I have the same issue, similar hardware (on mac os 14 and apple silicon) and it happens almost everytime I create a new project env and reinstall plots in the new local environment. May try to reinstall from scratch as well.

It manages to build but still will refuse to work. The build log has some warnings though :

[ Info: Found existing GR run-time in /Users/USER/.julia/packages/GR/cRdXQ/src/../deps/gr
┌ Warning: Assignment to `grdir` in soft scope is ambiguous because a global variable by the same name exists: `grdir` will be treated as a new local. Disambiguate by using `local grdir` to suppress this warning or `global grdir` to assign to the existing global variable.
└ @ ~/.julia/packages/GR/cRdXQ/deps/build.jl:164

jheinen · 2023-11-05T09:47:58Z

Unfortunately, I cannot reproduce the problem. Could you briefly describe in a minimal example/workflow how the problem arises for you.
