[cfe-dev] [PATCH] Make libc++ compile on linux (issue1164043)

[罗勇刚(Yonggang Luo)]

What's the building option for libc++ on ubuntu.
I was using such options
export CXX="g++ -std=c++0x"

And the build result is

./buildit
./buildit: line 15: [: g++: binary operator expected

Also there is a patch for buildit
