Hi, I’m brandnew to julia and I am facing a hard time while trying to run my analysis.

The situation is that I’m trying to run the package Circuitscape using JuliaCall within R in a custom docker container and I kept getting the same error. Circuitscape works just fine outside R environment when I open julia from linux terminal and I don’t have much clue of what is going on nor how to fix it.

Oh, this may be me being misled but on this line:

> /usr/lib/x86\_64-linux-gnu/libcurl.so: version `CURL\_4’ not found (required by /root/.julia/artifacts/8a643038d2adde781829b4467a32afa307e23b51/lib/libproj.so)

Curl is not detected in your container. Do you have curl installed in your system? Should be a quick `sudo apt-get install curl` or `sudo dnf install curl` within your container. Then, I’d suggest restarting R and Julia and seeing if that error goes away.

P.S. Welcome to the Julia community! 👋

Well, curl is already installed as a dependency for some R packages locally, I’m finding that it might be a library path conflict because when I run before starting R:

```julia
root@704676239b3d:/# export R_LD_LIBRARY_PATH=/home/julia-1.8.5/lib/julia:/usr/lib/R/lib:/usr/lib/x86_64-linux-gnu:/usr/
lib/jvm/default-java/lib/server::/root/.julia/artifacts/8a643038d2adde781829b4467a32afa307e23b51/lib

```

and try to do the same steps as I mentioned before the code works just fine with julia.

```julia
root@704676239b3d:/# R

> system("julia")

```

Although the application that I’m mainly running is implemented in R, and when I need to load it’s library I face the following:

```julia
> library(ResistanceGA)
Loading required package: raster
Loading required package: sp
Error: package or namespace load failed for 'raster' in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/usr/local/lib/R/site-library/terra/libs/terra.so':
  /home/julia-1.8.5/lib/julia/libcurl.so.4: version `CURL_OPENSSL_4' not found (required by /lib/libgdal.so.30)
Error: package 'raster' could not be loaded

```

So I kind of get the same error because now it is other version of libcurl.  
Would you have any insight on what should I do to solve this one?  
Something that I’d like to add is that when I start R and load this library without changing the R\_LD\_LIBRARY\_PATH it works just fine.  
And thank you for the quick response and welcoming in the community!! =D

Strange! I did some looking at the RCall.jl open GitHub Issues and found this discussion which seems very similar to the problem you are running into: [conflict libcurl.so in Julia 1.8 · Issue #475 · JuliaInterop/RCall.jl · GitHub](https://github.com/JuliaInterop/RCall.jl/issues/475)

CC @giordano as that conversation involved him as well.
