Hi,
The compiler will not accept this. My thought is a pointer to member
is a constant (an offset basically) but the compiler appears to
disagree with me. I just want to make sure I'm not doing a silly
syntax error. To me, it looks like 5.19 paragraph 6 says I can do
this but I could easily be mistaken. FYI: IBM's xlC complains about
it too.
class sge {
public:
uint64_t address;
uint32_t count;
uint32_t flags;
};
class bitfield {
public:
const uint32_t sge::*field = &sge::flags;
static const uint32_t bit_start = 31;
static const uint32_t bit_stop = 31;
};
g++ -o foo foo.C && ./foo
foo.C:14: error: 'sge::flags' cannot appear in a constant-expression
foo.C:14: error: `&' cannot appear in a constant-expression
foo.C:14: error: ISO C++ forbids initialization of member 'field'
foo.C:14: error: making 'field' static
foo.C:14: error: invalid in-class initialization of static data
member of non-integral type 'const uint32_t sge::*'
Thank you,
Perry
