Hi
C++ requires constant expressions to be known during compilation, not
at link time.
A constant that is not determined at compile-time is akin to
constructor that is const but not constexpr. While it remains
constant throughout the program, its value is established only
at link-time, not a

Hi
struct image
{
vec2 pos[2];
std::vector pixels;
};
Now if any of those structs are modified, members added or removed, it would
require recompilation of the whole code that uses it. This is because the
memory offsets to access the fields change and might fall out of the
displacement r

If we add or remove a member variable in class Vec, it requires
recompiling not only Vec.cc but also Pix.cc. I believ
And I heard "That's already here. ELF gABI does the same thing."
Anyway I can't implement it myself. I hope wide discussion.

I'd like to hear your opinion.
Can we once again promise that only modified files need to be recompiled?
Thank you.
My plan is to make a higher compatibility version of ELF.
You may be able to call it ELF2.0
