socket2 doesn't compile on ubuntu

[Merrick17]

when I try to compile I get this error error[E0425]: cannot find functionset_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: https://github.com/rust-lang/socket2/blob/3a938932829ea6ee3025d2d7a86c7b095c76e6c3/src/sys/unix.rs#L741-L760.

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 Compiling ring v0.17.8 Compiling socket2 v0.5.7 Compiling crunchy v0.2.2 Compiling digest v0.9.0 error[E0583]: file not found for modulesys` --> src/lib.rs:179:1	179	mod sys;	^^^^^^^^

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.

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.
