RStudio aborting fatal error after julia_setup() in Julia 1.6 #164

Closed rokapre closed 2 years ago

rokapre commented 3 years ago

Hello,

Recently Julia 1.6 was released and I am having problems with JuliaCall and the function julia_setup() in R. RCall in Julia works fine. I am able to point it to the 1.6 binaries and that part works fine but the issue is immediately afterwards RStudio seems to crash. In the terminal with just R (so not RStudio) I get a segmentation fault:

Prior to 1.6, JuliaCall was working fine so I don't know why this is happening. Any ideas? Are there alternatives to use Julia within R that work with 1.6?

I am using MacOS Catalina btw

Best,

Rohan

Thank you very much for the feedback!

From the error message, it seems that the segfault happens when JuliaCall tries to load the julia dll into R.

I just downloaded julia v1.6.0 on my Windows laptop, and JuliaCall works fine.

> library(JuliaCall)
> julia_setup("C:\\Users\\lch34\\AppData\\Local\\Programs\\Julia-1.6.0\\bin")
Julia version 1.6.0 at location C:\Users\lch34\AppData\Local\Programs\JULIA-~1.0\bin will be used.
Loading setup script for JuliaCall...
Finish loading setup script for JuliaCall.

I will try to test julia 1.6 on linux and MacOS soon to see if I can reproduce the error.

Best, Changcheng

I tried on both linux REHL7 system and MacOS Catalina. JuliaCall works okay with Julia 1.6 on REHL7 but the same error as reported happens on MacOS Catalina. I will investigate deeper to see why it happens.

Thanks for the timely report!

I came to report a similar issue on Mac Big Sur (11.2.2). If I run this code:

library(JuliaCall)
julia_setup(JULIA_HOME = "/Applications/Julia-1.6.app/Contents/Resources/julia/bin/")

RStudio (1.4.1103) crashes:

Wondering if there are any updates on this issue. I tried again today after installing JuliaCall again, but I ran into the same problem. Are there any other ways right now to call Julia in R?

A work-around is to change the process directory to the libjulia path before calling jl_init: https://discourse.julialang.org/t/segfault-when-jl-init-in-r-also-python-with-julia-1-6-on-macos/58110/5?u=ihnorton
