hi i m trying to install caffe on mac 10.9.5 when installing boost, it reports:

Error: private method cxx=' called for #<Object:0x007f9f2a8cd248> Please report this bug: https://git.io/brew-troubleshooting /usr/local/Library/Taps/mitmul/homebrew-caffe/boost-std.rb:73:ininstall' /usr/local/Library/Homebrew/build.rb:136:in block in install' /usr/local/Library/Homebrew/formula.rb:410:inblock in brew' /usr/local/Library/Homebrew/formula.rb:766:in block in stage' /usr/local/Library/Homebrew/resource.rb:91:inblock in unpack' /usr/local/Library/Homebrew/extend/fileutils.rb:17:in mktemp' /usr/local/Library/Homebrew/resource.rb:88:inunpack' /usr/local/Library/Homebrew/resource.rb:81:in stage' /usr/local/Library/Homebrew/formula.rb:764:instage' /usr/local/Library/Homebrew/formula.rb:406:in brew' /usr/local/Library/Homebrew/build.rb:114:ininstall' /usr/local/Library/Homebrew/build.rb:185:in `

thanks

solution is to replace

ENV.cxx = "/usr/bin/clang -stdlib=libstdc++"

in /usr/local/Library/Taps/mitmul/homebrew-caffe/boost-std.rb file with

ENV["CXX"] = "/usr/bin/clang++ -stdlib=libstdc++"

refered from https://github.com/BVLC/caffe/issues/449

If anyone needs it, still:

brew install https://gist.githubusercontent.com/mutaphysis/2880e3866a48a954a310/raw/1509daea679b0e685cf49907db7a70408741593c/protobuf-std.rb

I'm getting this message when trying the first solution listed above
