GR build problems: "installation is incomplete"

compleat · April 8, 2021, 12:31pm

Thanks for your work on this. Is it possible to include the suggestion above about the error message - that in the case of the ‘incomplete build’ issue (which gave rise to this thread) the error message would include the suggestion to set GRDIR to “”

Thanks!

If what I did was successful, GR.jl should just do that automatically for you:

github.com

jheinen/GR.jl/blob/master/src/GR.jl#L304


      
              GKS_NO_GUI - no initialization is done
              GKS_IGNORE_ENCODING - Force use of UTF-8 for font encoding, ignore GKS_ENCODING
          
              Environmental variables set by `init`:
              GKS_FONTPATH - path to GR fonts, often the same as GRDIR
              GKS_USE_CAIRO_PNG
              GKSwstype - Graphics workstation type, see help for `openws`
              GKS_QT - Command to start QT backend via gksqt executable
              GKS_ENCODING - Sets the text encoding (e.g. Latin1 or UTF-8)
          """
          function init(always::Bool = false)
              if !libs_loaded[]
                  load_libs(always)
                  return
              end
              if check_env[] || always
                  haskey(ENV, "GKS_FONTPATH") || get!(ENV, "GKS_FONTPATH", GRPreferences.grdir[])
                  ENV["GKS_USE_CAIRO_PNG"] = "true"
                  if "GRDISPLAY" in keys(ENV)
                      display_name[] = ENV["GRDISPLAY"]
                      if display_name[] == "js" || display_name[] == "pluto" || display_name[] == "js-server"

I can simulate the problem by doing using GR; rm(GR.depsfile) and then starting a new Julia session:

As you can see we encounter the “incomplete build” issue here, but GR.jl rebuilds itself automatically and even still makes the plot for you!

If it still cannot recover, then it indeed does provide your suggestion:

github.com

jheinen/GR.jl/blob/master/src/GR.jl#L320-L329


      
                      key = Sys.isapple() ? "DYLD_FALLBACK_LIBRARY_PATH" : "LD_LIBRARY_PATH"
                      "env $key=$(GRPreferences.libpath[]) $(GRPreferences.grplot[]) --listen"
                  end
                  GR.startlistener()
                  ENV["GKS_WSTYPE"] = "nul"
              end
              @debug "Found GRDISPLAY in ENV" display_name[]
          elseif "GKS_NO_GUI" in keys(ENV)
              @debug "Found GKS_NO_GUI in ENV, returning"
              return

Awesome! Thank you!

To the OP, I feel your pain. FWIW, I just ran into a problem caused by the intersection of GR, Plots, and PyPlot (GR issue 392). After hours of troubleshooting, I discovered that the most recent GR version, 0.57.3, was picking up multiple Qt libraries on my system. Restricting the version to 0.55.0 has resolved it for me. Maybe not directly related to the direct issue discussed here, but it speaks to the larger problems of the Julia packaging ecosystem. Hopefully it continues to improve.
