[Insight-users] Compiling Error After upgrading MacOS and Xcode

[Bradley Lowekamp]

The new compiler with OSX Maverics turns on C++11 by default. This needs to be explicitly disabled when configuring ITK <4.5

From a new directory, which has not been configured before run the following to perform an initial configuration:

cmake -DCMAKE_CXX_FLAGS:STRING='-stdlib=libstdc++ -std=c++03'  ../ITK

This with tell the compiler to use C++03 during the configuration and build. 

Many in the community are actively working to improve the C++11 support in ITK. You would need to checkout the master branch from the git repository to try out these new changes.

Good luck,
Brad
