I got complacent developing my game on a Mac and Linux boxes so far, and have neglected to actually compile my game on Windows, even though I from the start did intend Windows as a first-class deployment target. I’ve finally gotten around to it, and to no surprise, it’s not been particularly smooth. But some of the problems have been surprising to me.
One I had not previously encountered is this: One portion of my game uses a CRTP (Curiously Recurring Template Pattern) base, that abstracts away some repetitive bits that several derived types need. It looked something like this:
struct Meta {
const char *stuff;
};
template <typename Derived>
struct Helper {
static constexpr Meta kMeta = { Derived::kStuff };
};
struct Foo : Helper<Foo> {
static constexpr const char *kStuff = "stuff";
};This works fine on GCC, Clang, and ICC. But MSVC?
error C2039: 'kStuff': is not a member of 'Derived'No way!
