I can compile it fine on Ubuntu 12.04 with GCC/G++ 4.7. Below are the
commands I used to get GCC updated to 4.7 and my cmake command.
### GCC UPDATE ###
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.7 g++-4.7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 60
--slave /usr/bin/g++ g++ /usr/bin/g++-4.6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 40
--slave /usr/bin/g++ g++ /usr/bin/g++-4.7
sudo update-alternatives --config gcc
### GCC UPDATE ###
### WT BUILD CMDS ###
cmake -G 'Unix Makefiles' -DWT_CPP_11_MODE=-std=c++11
-DCMAKE_INSTALL_PREFIX=/usr/local -DCONNECTOR_FCGI=1 -DCONNECTOR_HTTP=1
-DBUILD_EXAMPLES=1 -DCMAKE_BUILD_TYPE="RelWithDebInfo"
-DEXAMPLES_CONNECTOR="wtfcgi" ../
make
make install
