what c++ norme i'm currently using?
c++, c++11, compiler-construction, linux
Solution
That can be a tricky question. C++11 refers to a version of the standard, not to a version of the compiler. Different compilers, and different versions of any given compiler, will typically implement a mix of versions of the standard, at least for recent versions. More or less, because any implementation of C++11 will be fairly new, and thus probably fairly buggy.
Most compilers have options to output the version; many will output it systematically in verbose mode. For g++, try `g++ --version`. Recent versions of g++ do have some support for C++11, but you have to activate it with `-std=c++0x` (rather than the usual `-std=c++03` or `-std=c++98`). As the name (`c++0x`, rather than `c++11`) indicates, it is not truly C++11; it is an implementation of some (most?) of the major new features, in a preliminary version based on various working papers, and not the final standard.
(FWIW: I don't think any compiler fully implements all of C++11, but I'd love to be proven wrong.)
Problem
Recently I had faced compiling errors in a c++ code I wrote so I've been asked if I was using a C++11 compiler, but honestly I don't know how to check on my compiler version ! so any idea how to figure this out ?? Btw I'm using codeblocks as an IDE which includes the GCC compiler and GDB debugger from MinGW. also if I'm compiling my c++ code under Linux what command should I run to know my compiler version ?
