In some circumstances, a user may encounter the following error.
Failed to precompile Plots [91a5bcdd-55d7-5caf-9e0b-520d859cae80] to "~/.julia/compiled/v1.9/Plots/jl_crbDAx".
ERROR: LoadError: InitError: UndefVarError: `GR_jll` not defined
@ GR.GRPreferences ~/.julia/packages/GR/jehu0/src/preferences.jl:64
A persistent error such as this may require the following command to force GR to recompile.
This situation occurs due to some initial problem with loading GR_jll on this line:
However, due to the surrounding try-catch the problem is ignored and compilation continues. Once the compilation succeeds, the issue may persist if Julia fails to recognize the need to invalidate the compile cache for GR.
If the above does not resolve the issue, first assess if there is a problem loading GR_jll with the following steps in a fresh Julia session (restart Julia):
Pkg.activate(; temp = true)
If that succeeds, then try the following.
If GR function works, then try adding Plots.jl
An alternate approach to using Base.compilecache would be to manually locate the files in ~/.julia/compiled/v1.9 for GR and remove them.
Interesting. So if ENV[“GRDIR”] is set to a local build, import GR_jll will throw an error? Is that still the case now that we are not automatically loading any shared libraries via GR_jll due to using dont_dlopen=true in the recipe?
@jheinen, could you test if we still need that try - catch block in your environment?
If GR_jll still throws an error on import, I wonder it would make sense to develop a placeholder GR_jll that is just empty?
I still wonder if we can insert something under if binary == "GR_jll" where GR_jll is presumed to be loaded to catch the condition where GR_jll is still undefined and then recommend the compile cache fix above?
