ENV.cxx detecting system g++ not Brew g++ #1035
Description
I was just writing a new formula today for the SDSL-Lite library and am having strange issues with the test block where I compile a small .cpp file for library. It's C++11.
% which g++
/bio/linuxbrew/bin/g++
% g++ --version
g++ (Homebrew gcc 5.3.0) 5.3.0
> puts ENV.cc # in test block
/usr/bin/gcc
> puts ENV.cxx # in test block
/usr/bin/g++
> ENV.cxx11
The selected compiler doesn't support C++11: gcc
/bio/linuxbrew/Library/Homebrew/extend/ENV/std.rb:318:in `cxx11'
This is the code, which assumes that g++ has it's version suffixed on it?
def cxx11
if compiler == :clang
append "CXX", "-std=c++11"
append "CXX", "-stdlib=libc++"
elsif compiler =~ /gcc-(4\.(8|9)|5)/
append "CXX", "-std=c++11"
else
raise "The selected compiler doesn't support C++11: #{compiler}"
end
end

Merge branch homebrew/master into linuxbrew/master
Conflicts:
Library/Homebrew/extend/ENV/std.rb
Maybe something to do with new HOMEBREW_ENV_PATH ?
Or #1033 ?
