homebrewでjuliaのHEADのインストールに失敗した時にするといいこと

More than 5 years have passed since last update.

Yosemiteにあげたあととか、gccのアップデートがからんでjuliaのHEADのインストールが死ぬ時があります。

brew reinstall julia --HEAD
(...snip...)

こういうときは、慌てず騒がずarpackとopenblasをsourceからインストールし直しましょう。

brew rm arpack-julia openblas-julia
brew install --build-from-source arpack-julia openblas-julia
brew reinstall julia --HEAD --with-accelerate

よくわからなくて、make distclean && makeしてたのに、これだけで十分とは...。
