Fails to build on non-Linux

[jbeich]

Regressed by b469d9e. Affects downstream package. CC @unrelentingtech

• FreeBSD >= 13.0 has memfd_create(3) but rust-lang/libc@0a57541a7101 cannot be used due to How to deal with breaking changes on platform ? [BSDs related] rust-lang/libc#570. memfd_create can be replaced with shm_open(SHM_ANON, ...) which is supported on all FreeBSD versions.
• OpenBSD has shm_mkstemp(3) but not exposed in libc crate
• DragonFly and NetBSD have neither

Thanks for the report!

I guess https://lib.rs/crates/shmemfdrs can be used?

[MaxVerevkin]

Please try 5e836c6

Builds fine on FreeBSD amd64 and works fine under Sway 1.7 now. Building on DragonFly or FreeBSD i386/aarch64/powerpc64/etc is blocked by https://github.com/unrelentingtech/shmemfdrs/issues/5.

[MaxVerevkin]

I'm okay with depending on a specific git commit instead of a tag if it helps.

Should be ready now. Can you update dependencies or just shmemfdrs?

$ cargo update -p shmemfdrs
    Updating crates.io index
    Removing sc v0.2.7
