Fails to find libLLVM on anaconda

[sargas]

I'm not sure if this is a problem with the conda-forge julia package or this package, but using a package that requires BinaryProvider.jl with Anaconda fails to find the libLLVM symbols.

On a Linux system with docker, this can be reproduced by running:

docker run continuumio/anaconda /bin/bash -c "/opt/conda/bin/conda install -c conda-forge -yq julia && julia -e 'using Pkg; Pkg.add(\"ZMQ\")'"

This results in the following error:

This was not the case for Julia 0.6.1, although that used BinaryProvider v0.3.3

I have the same issue with MacOS 10.12 + anaconda + Julia 1.01 (installed with conda), when trying to install a jupyter notebook kernal.

[Solved] Now I tried to use a non-conda-installed version of julia 1.0.1, and the problem disappeared.

[rabernat]

Is there any solution to this using the conda-installed version?

[tiagopereira]

Same error here. Unable to build ZMQ and MbedTLS.

[alibeyram]

Same here. Any update?

[Irratzo]

Same here. My purpose was to use DifferentialEquations.jl in jupyter, in my setup (precompiled binary package julia 1.0.3; anaconda environment 'julia' with installed julia 1.0.2, conda 4.5.12).

# in precompiled binary package julia (not the conda env julia):
julia
julia> Pkg.add("DifferentialEquations")

UPDATE: this advice for symlinking llvm fixed the LLVM issue. Although my original problem (install DifferentialEquations.jl in conda julia) now failed because of another issue I call the 'Arpack error'. If you have the same purpose and run into that error as well at this point, here is how I fixed it.

Maybe this issue should be merged with (or vice versa) https://github.com/JuliaLang/julia/issues/29720 ?

It also seems to be discussed here: https://github.com/conda-forge/julia-feedstock/issues/60

[krinsman]

Since this is an issue with the conda-forge julia package, the solution might be found in the current build script for that package, found here:

https://github.com/conda-forge/julia-feedstock/blob/master/recipe/build.sh

In particular, note that the package does not install the conda-forge llvm package for Julia to use by default, and that the following flag is used in the make: USE_SYSTEM_LLVM=0.
