I tried it on my CentOS 6.6 system and it failed. (Although your test program did not give any errors.) $ ./configure ... checking whether g++ supports C++11 features by default... no checking whether g++ supports C++11 features with -std=gnu++11... no checking whether g++ supports C++11 features with -std=gnu++0x... no checking whether g++ supports C++11 features with -std=c++11... no checking whether g++ supports C++11 features with +std=c++11... no checking whether g++ supports C++11 features with -h std=c++11... no checking whether g++ supports C++11 features with -std=c++0x... no checking whether g++ supports C++11 features with +std=c++0x... no checking whether g++ supports C++11 features with -h std=c++0x... no configure: error: *** A compiler with support for C++11 language features is required. $ gcc -v Using built-in specs.

I'm not sure if that would make a difference or not. I may be able to try it in a few days if you don't have another solution. -- Bowie ------------------------------------------------------------------------------ Announcing the Oxford Dictionaries API!
