 If you want to build using C++11, then:

-    make

 LLVM's libc++ is also supported, so you can:

 

-    CXXFLAGS="-std=c++11 -stdlib=libc++"

+    export CXXFLAGS="-std=c++11 -stdlib=libc++"

     make

 

+If you target 32-bit IA-32 machines (i386, i586 or i686), then the makefile forgoes -fPIC due to register pressures. You should add -fPIC yourself in this case:

+

+    CXXFLAGS="-DNDEBUG -g2 -O3 -fPIC" make

+

+You can also override a variable so that only your flags are present. That is, the makefile will not add additional flags. For example, the following build with only -std=c++11:

+

+    make CXXFLAGS="-std=c++11"
