Problems installing on 10.9

[sje30]

On my shiny new mac runnnig 10.9, I get the following error with installing julia. Any clues?

brew install --HEAD julia

Yes, is because the current release of OpenBLAS doesn't yet have your CPU type recorded (It's too new, lucky you). See this issue for discussion. The fix is to manually tell the openblas-julia formula what CPU it should target. Here is a list of values that you can use as the target; I would guess that SANDYBRIDGE is as close as we can get to your CPU type.

So you would need to do this: brew install openblas-julia --target=SANDYBRIDGE, and then everything should work for you.

Thank you! trying the compile with --target=SANDYBRIDGE installed openblas-julia; then "brew install julia --HEAD" compiled.

However, testing failed immediately:

$ brew test -v julia
Testing julia
Error: julia: failed

Running the julia binary works though; should I ignore the failure on the test?

[staticfloat]

You're not the only one to report this testing error.

What happens if you open up julia and run this:

cd(joinpath(JULIA_HOME,"../share/julia/test"))                           
push!(ARGS,"all")
include("runtests.jl")

[sje30]

Thanks. Typed that and I got lots of lines of the sort:

julia> include("runtests.jl")
    From worker 8:       * hashing
    From worker 3:       * keywordargs
    From worker 5:       * strings
    From worker 6:       * unicode
    From worker 4:       * numbers

ending in:

    From worker 7:       * ranges
    SUCCESS

Thank you!

Looks like all the tests are passing then. I'm not sure why brew thinks they're failing, but perhaps there is some kind of transient error. Thank you for testing for me! If weird stuff crops up in the future, please re-open this issue.

[sje30]

Sure. thank you for the prompt support. Let me know if you need anything testing relating to these two issues (SANDYBRIDGE/ "brew test -v julia").

[staticfloat]

Aha! I think I just figured something out; Does brew test -v --HEAD julia work for you?

[sje30]

Yes!

$ brew test -v --HEAD julia
Testing julia
==> /usr/local/Cellar/julia/HEAD/bin/julia runtests.jl all
    From worker 3:       * keywordargs
...
    From worker 4:       * ranges
    SUCCESS

thanks.

[staticfloat]

Fantastic. I've updated the docs to make this a little clearer.

also, just confirmed that below works on works on 10.9.2

brew install openblas-julia --HEAD
brew install julia
brew test -v julia
