Subject: lang/rust Port - Missing proc-macro-srv binary

 
Hi Sebastien,

I've been playing around with Rust on OpenBSD and hit a wall with 
rust-analyzer not wanting to expand macros. Turns out this is because of a 
missing binary at /usr/local/libexec/rust-analyzer-proc-macro-srv.

Looks like rust-analyzer uses this binary to hook into whatever version of 
rustc you're running to expand macros.

I was able to generate the binary by adding rust-analyzer to the tools 
section and at do-build. I've attached a cvs diff.

Because the version of rust-analyzer on my system was too old I then had 
to switch to 0.0.307 from crates.io but it worked fine after that.

sysctl -n kern.version shows:

OpenBSD 7.8 (GENERIC) #54: Sun Oct 12 12:45:58 MDT 2025
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC

The CVS tag shows: TOPENBSD_7_8

Let me know if there's somewhere else I should send this or if you need 
any more info. I'm a barista from Australia and just a hobbyist programmer 
so apologies if I've bothered the wrong person, bit new to this.

Many thanks,
Madeline Baggins
