Autotools/libtool link library with libstdc++ despite -stdlib=libc++ option passed to configure

autotools, c++11, clang, glog, libtool

Solution

It's better to put 'dialect' and runtime flags in the compiler variable, since it will use those flags for linking - not just source compilation: `CXX="clang++ -std=c++11 -stdlib=libc++"`

Save `CXXFLAGS` for things like `-W -Wall -O2 -march=xxx`, etc.

Problem

I'm trying to build google-glog on Mac OS X 10.8, using following options: ./configure CXX='clang++' CXXFLAGS='-std=c++11 -stdlib=libc++' Despite that the library gets linked with libstdc++. Why, and how to fix this?
