Cxx.jl

Cxx.jl copied to clipboard

This has happened to me on two systems:

• Native Arch Linux/Julia 0.6.2
• Windows 10 WSL Arch Linux/Julia 0.6.2

I can build Cxx fine, but the following happens when I try to use it:

julia> using Cxx
INFO: Precompiling module Cxx.

Same here on Arch linux, julia 0.6.2. The problem seems to be loading libcxxffi.so

Arch linux may have upgraded some required dependency before any other distro has, I've had a similar problem recently with fortran binaries.

same as rafaqz here (archlinux/julia 6.2). Anyone found a fix yet?
