I am playing with unique_ptr. In my last post people helped me compiling a program that used this pointer by specifying the -std=c++0x during compilation.
Now i was wondering if
I guess you should add __GXX_EXPERIMENTAL_CXX0X__ definition to your "Paths and Symbols" in Eclipse. See also this question GNU C++ how to check when -std=c++0x is in effect? and the same question Eclipse indexer can't resolve shared_ptr for shared_ptr.
