In older gcc versions (~6.X) the following code worked, however with newer version there are compile-errors.
struct test{
constexpr static int* PORT1 = reinterpret_cast<int*>(0x12345678);
};
Compiler:
error: reinterpret_cast from integer to pointer
A C-like cast doesnt work either.
Note: Its for memory-maped-io, so i really want to read/write to a fixed address
