path to julia-config.jl in mexjulia-rebranding/Jl.m incorrect for OS X installation #17

Closed Divisible8737 closed 8 years ago

Divisible8737 commented 8 years ago
  1. I cloned https://github.com/twadleigh/mexjulia/tree/rebranding
  2. Opened matlab, surfed to mexjulia-rebranding, verified that my C++ compiler was set up, and then ran
>> Jl.build
The path of the Julia executable is /Users/y9KAaixxegjR/Documents/Current_works/julia/usr/bin/julia
Error using Jl.build (line 89)

I placed a breakpoint at line 89 in Jl.m and found that 

K>> cfg

cfg =

/Users/y9KAaixxegjR/Documents/Current_works/julia/usr/share/julia/julia-config.jl

but my julia-config.jl file is actually at:

/Users/y9KAaixxegjR/Documents/Current_works/julia/contrib/julia-config.jl

Here is my julia version info:

P.S. I built julia with 'make' as per the instructions on github's main julia page.

twadleigh commented 8 years ago

As I mentioned in #18, the issue is that the build logic currently assumes an "installed" julia (e.g., one that you might get from running make install after make, or downloaded). I think the julia-config.jl script itself only works on a julia installation, and not a julia run from the source tree.

I don't believe there is any technical obstacle to getting mexjulia to run on a julia built in the source tree, it just needs to be done. The reason the build is done purely in MATLAB is to support those users who may not have a full build chain. However, to support those users who want to use mexjulia with a source-tree version of julia, we can assume they have a full build chain, in which case a separate build path implemented via a Makefile is probably appropriate.

OK, thanks, I went ahead and downloaded the distributed version of julia, now I get this error, which does not appear to be just a path issue:
