C++ Not letting me use other constructor in initialization list

I'm trying to have a constructor call other constructors in their initialization list for I don't have duplicate logic. Here is what my .h file looks like:

class Button : public Component
{
public:
    Button(int x, int y, int width, int height, string normalSrc, string hoverSrc, string downSrc);
    Button(int x, int y, int width, int height, string normalSrc, string hoverSrc, string downSrc, Uint8 r, Uint8 g, Uint8 b);
    Button(int x, int y, int width, int height, string src) : Button(x, y, width, height, src, src, src) { }
    Button(int x, int y, int width, int height, string src, Uint8 r, Uint8 g, Uint8 b) : Button(x, y, width, height, src, src, src, r, g, b) { }
    ~Button();

but when I try to compile (using -std=c++0x as an extra compiler flag) I get this error:

In file included from /home/villages/Desktop/ogam-january-pipes/src/Vesper/Ui/Button.cpp:8:0:
/home/villages/Desktop/ogam-january-pipes/src/Vesper/Ui/Button.h: In constructor ‘Button::Button(int, int, int, int, std::string)’:

make[2]: *** [CMakeFiles/Villages.dir/src/Vesper/Ui/Button.cpp.o] Error 1
make[1]: *** [CMakeFiles/Villages.dir/all] Error 2
make: *** [all] Error 2

What am I doing wrong?

Thanks!

You are using the wrong compiler/version. The delegating constructors feature is a C++11 feature, and not all compilers have caught up yet.

According to this table GCC supports it since 4.7, Clang since 3.0, and MSVC since Nov 2012 CTP.
