LoadError: UndefVarError



I am trying to install Cxx on Julia and when I do Pkg.build(“Cxx”) I get the following error:

julia> Pkg.build(“Cxx”)
Building Cxx → ~/.julia/packages/Cxx/E2Qs/deps/build.log
┌ Error: Error building Cxx:

Any ideas on how to resolve this issue?


It looks like you’re using the v0.7-alpha release of Julia, which is not supported by any of the released versions of Cxx.jl. If you want a more stable package experience, use the stable v0.6.3 release of Julia.


Got it working. Thank you so much!
