Mac binary distribution incomplete.

[juhagman]

I downloaded the binary distribution for OS X. It does not start because libamos is linked against libgfortran, which does not come with the binary distribution.

$ ./julia dlopen(/Users/jhagman/Downloads/julia/lib/libamos.dylib, 2): Library not loaded: /usr/local/lib/libgfortran.3.dylib Referenced from: /Users/jhagman/Downloads/julia/lib/libamos.dylib Reason: image not found error during init: could not load module libamos in dlopen, /Users/viral/julia/j/base.j:97 at string:15

[JeffBezanson]

For now we are requiring gfortran to be installed separately rather than bundling it. See the readme for instructions.

[whoisjake]

Not re-opening, but the documentation around install gfortran via homebrew should probably change as it doesn't create the library :)

[JeffBezanson]

I don't have a mac to try this on; what should the README say?

[whoisjake]

I'll let you know after some more experimentation tomorrow. At the moment, the gfortran build on homebrew does not provide /usr/local/lib/libgfortran.3.dylib.

So I would imagine the other distributions mentioned contain that library.

My suggestion would be just to remove the note on building gfortran with homebrew until it could be used.

[whoisjake]

So I tried installing gfortan from: http://gcc.gnu.org/wiki/GFortranBinaries (Which is one of the other suggestions in the README)

libamos.dylib is fine, but now libarpack complains:

Neoterius:julia jake $ ./julia
dlopen(libarpack, 2): image not found
error during init:
could not load module libarpack
in dlopen, /Users/viral/julia/j/base.j:99 sys.ji:17

Neoterius:lib jake $ otool -L libarpack.dylib

I'm on OS X 10.7.3 with XCode Version 4.1 (4B110)

I'll try the third package today to see if that works... This could be related to #375 and #389.

[whoisjake]

I know I'm beating a dead horse here, but maybe the instructions for homebrew gfortran and the particular download were only for the compilation instructions? I should have noted that I'm only using the pre-compiled binary package.

Still... regardless, I'm not sure it would work anyway...

[kbarros]

I also experienced the problem that Homebrew's installation of gfortran doesn't properly install the gfortran library, described here: Homebrew/legacy-homebrew#8539 . If someone knows how to get Homebrew's gfortran to work with Julia, please let us know.
