CCALL : import path not working properly to load externall dylib / dll about atom-julia-client HOT 3 CLOSED

You should get the environment variables into Atom if you start it from the command line.

About the Image not found error after adding DYLD_LIBRARY_PATH to ENV: You seem to have forgotten the leading : in front of the path (judging by you screenshot).

So hopefully either starting Atom from the terminal (and thus importing the correct enironment variable) or fixing the typo in your code should do the trick.

I effectively get all the env variables when launching atom with the atom command from the terminal.

Then, this sample of code works fine :

function myasum(n::Integer, X::Vector{Float64}, incx::Integer)
  ccall((:dasum, :libmkl_rt),
        Float64,
        (Ptr{Int64}, Ptr{Float64}, Ptr{Int64}),
        &n, X, &incx)
end

myasum(3,Float64[1,2,3],1)

But when I start atom from the icon app, even if I set the correct ENV variables by hand before my ccall to mkl_rt.dylib, I get a not found error :

for e in ENV
  println(e[1],"\t\t","=>",e[2])
end

ENV["DYLD_LIBRARY_PATH"] = ":/opt/intel/mkl/lib:/opt/intel/lib"
ENV["PATH"] = ENV["PATH"] * ":/opt/intel/compilers_and_libraries_2016.0.083/mac/mkl/lib:/opt/intel/mkl/lib:/opt/intel/lib"

for e in ENV
  println(e[1],"\t\t","=>",e[2])
end

function myasum(n::Integer, X::Vector{Float64}, incx::Integer)
  ccall((:dasum, :libmkl_rt),
        Float64,
        (Ptr{Int64}, Ptr{Float64}, Ptr{Int64}),
        &n, X, &incx)
end

myasum(3,Float64[1,2,3],1)

Is this an expected behaviour ??

I don't know, but suspect that this isn't intended behaviour (the part with actively setting ENV and dlopen still not working -- Atom not importing PATH when not started from the shell is a known issue).

What you could also try as a workaround is setting Libdl.DL_LOAD_PATH because dlopen should use that for looking up libraries first...
Also: There's not much I know about how the interaction between ENV, dlopen, and the system environment variables actually works, only about how I would suspect them to -- therefore my debugging advice/help is more like wildely guessing at stuff ;) You may want to ask the mailing list about this (and link to this issue) -- someone there surely knows more about that stuff than me.
