Question about global constructors

[sleepy-monax]

Yes you have to have them or gcc will complain '^^

[sleepy-monax]

If I recall correctly, the global constructor isn't getting called in the kernel

[RossComputerGuy]

If constructors aren't getting called then I think they shouldn't be added in, it'll save up binary space.

[sleepy-monax]

It's C so there is no constructor to call, at least in the kernel, I know there is one in libposix to initialize stdio

aa ok,
here the link: https://wiki.osdev.org/Calling_Global_Constructors#Using_crti.o.2C_crtbegin.o.2C_crtend.o.2C_and_crtn.o_in_a_Kerne
I have been reading about this article on osdev.org, in skifos I thought I saw the call to these constructors
@RossComputerGuy
That means that I don't necessarily need to call the builders, isn't it an obligation for the kernel?

[sleepy-monax]

Yes there is one call to init in the userspace side of libsystem

@NicolasVanBossuyt good thank you, crt0.o crti.o, crtn.o
Isn't it really necessary to call these files objects?
that is mentioned in the osdev article

Very Thanks!
