socket2 doesn't compile on ubuntu

[Merrick17]

when I try to compile I get this error
error[E0425]: cannot find function set_msghdr_controlin modulesys--> src/lib.rs:714:14 | 714 | sys::set_msghdr_control(&mut self.inner, buf.as_mut_ptr().cast(), buf.len()); | ^^^^^^^^^^^^^^^^^^ not found insys`

Can you share the command you're using to build socket2?

Because the functions are very much defined:

socket2/src/sys/unix.rs

Lines 741 to 760 in 3a93893

	#[cfg(not(target_os = "redox"))]
	pub(crate) fn set_msghdr_control(msg: &mut msghdr, ptr: *mut libc::c_void, len: usize) {
	msg.msg_control = ptr;
	msg.msg_controllen = len as _;
	}
	#[cfg(not(target_os = "redox"))]
	pub(crate) fn set_msghdr_flags(msg: &mut msghdr, flags: libc::c_int) {
	msg.msg_flags = flags;
	}
	#[cfg(not(target_os = "redox"))]
	pub(crate) fn msghdr_flags(msg: &msghdr) -> RecvFlags {
	RecvFlags(msg.msg_flags)
	}
	#[cfg(not(target_os = "redox"))]
	pub(crate) fn msghdr_control_len(msg: &msghdr) -> usize {
	msg.msg_controllen as _
	}

sorry I guess I didn't make my self clear , okayb first issue I'm using orao vrf which has socket2 as a depencies, if I follow the correct error stack it starts from here

I still need the command you're running, e.g. cargo build etc. If you are using a different target for example this might cause issues. This fact that you're hitting compile_error!("Socket2 doesn't support the compile target"); indicates your not compiling for Linux.

P.S. Can you put the output in between "```" (three backticks) on a separate line, that would make it more readable on GitHub.

[Merrick17]

okay sorry ,
so basically what I'm doing is creating a solana/anchor program , I've added https://github.com/orao-network/solana-vrf which as it seems uses the socket2 as a dependency .
I've runned "Anchor build" to build the program but it fails as shown

[Thomasdezeeuw]

I still don't know what OS you're targeting... can you enable some kind of debug/verbose logging? At some point anchor build should call cargo or rustc, I'll like to know what kind of flags are passed. Specifically --target.

[Merrick17]

hopefully this helps , can't find anything else that I can help even with Anchor commands , I've already opend same issue with VRF library

[Thomasdezeeuw]

I don't what anchor or solana are, so I don't know how they are using socket2. I think it would best if you open a ticket with the anchor project, maybe they can help you better.
