Error: cannot call member function `Foo* Foo::instance() const' without object Error message: cannot call member function `Foo* Foo::instance() const' without object. The faulting class is not the one that GCC complains about but one of the classes included from the file containing the class declaration GCC nags you about. Btw.

For right now if you get a segmentation fault you should check several things. (1) make sure that you have a format string as the first argument of all printf and The `x' prefix will indicate what language for C++ specif errors/warning it should differ from the C prefix. warning: char format, different type arg (arg 2) was generated by this statement: scanf("%s", &numberstring); because numberstring is an array and doesn't need the ampersand.

error: stray ‘\32' in program what does this mean and how do I fix it? You have defined foo in the header file, but not implemented it.
