mex file does not build in Jl.m for an OSX installation

[Divisible8737]

This is a continuation of issue #9, running on OSX El Capitan.

1. I hacked the correct file path for julia-config.jl into Jl.m (adding an extra line of code)
2. The next error I get when running Jl.build is

>> Jl.build
The path of the Julia configuration script is /Users/y9KAaixxegjR/Documents/Current_works/julia/contrib/julia-config.jl
Error using Jl.build (line 108)
Error: The input character is not valid in MATLAB statements or
expressions.

With a breakpoint on 108

% build the mex file
Line 106: src = fullfile(Jl.this_dir, 'mexjulia.cpp');
Line 107: mex_cmd = 'mex -largeArrayDims -O %s %s %s %s';
Line 108: eval(sprintf(mex_cmd, cflags, ldflags, src, ldlibs));

The variables are:

K>> src
src =
/Users/y9KAaixxegjR/Documents/Current_works/CodingProjects/mexjulia-rebranding/mexjulia.cpp

K>> mex_cmd
mex_cmd =
mex -largeArrayDims -O %s %s %s %s

sprintf(mex_cmd, cflags, ldflags, src, ldlibs)

ans =

Perhaps this is an issue with how I am building julia?

Can I presume that you build your own julia but don't use make install? I think in that case the assumptions of julia-config.jl don't work. I also have been assuming an installed julia. I don't believe there should be any obstacle to supporting this, but it would involve having more/separate logic for building in this case.

I've made lots of updates to the build process. I'm closing this. Please open new issues as you find them.
