These two lines seem to be redundant.

Thank you for doing this. We do a similar thing in cargo.mk and I never got around to trying this in lang/rust too.

Can you please delete files/patch-src_vendor_openssl-sys_.cargo-checksum.json too?

[kbowling]

I would prefer to see this bootstrapped and only for 12.0

[mikael]

I managed to build cargo with OPENSSL_STATIC=yes

[jbeich]

Please, land before D18427 if you plan to MFH to 2018Q4.

lang/rust builds on 12.0-RC3, but I have a problem building devel/rust-cbindgen.

error[E0412]: cannot find type `c_long` in the crate root

https://talos.anongoth.pl/data/powerpc64-default/2018-12-05_22h39m09s/logs/errors/rust-cbindgen-0.6.7.log

Is the built rust compiler 100% functional? This port builds on amd64.

[jbeich]

@pkubaj_riseup.net, bundled libc-0.2.41 doesn't support powerpc* on FreeBSD. Which version does or which part do you need backported?

[jbeich]

libc crate is used by pretty much every lang/rust consumer. If you don't land powerpc64 support upstream maintaining patches in consumers with vendored dependencies (e.g., net-im/fractal, www/firefox) is going to be hard.

[pkubaj]

Currently there's no support for any powerpc* on FreeBSD (https://github.com/rust-lang/libc/tree/master/src/unix/bsd/freebsdlike/freebsd).

I guess it's better to fix lang/rust alone for now and then take care of libc. Fixing lang/rust will make it much easier to fix other Rust-related ports because of no need to bootstrap on other architecture.

[mikael]

What is needed for this to be moved along?

A rebase after recent changes and a promise to attempt to upstream the libc crate and other patches.

I've just copied the bootstrap files to LOCAL/tobik/rust, so please add it to MASTER_SITES for {rust,cargo,std}_bootstrap too.

I can try to submit my patch upstream if they accept non github submission. It'll also be easier for me if all the aarch64 patches are submitted first.

[tobik]

Thank you.

I've added the bootstraps to my ~/public_distfiles/rust. Let's wait for it to appear. In the meantime there is a problem with extra-patch-arm-ppc.

Drop that one. It isn't used anywhere.

USE_GCC=8 ?

(On Diff #53956)

This patch has x86 and DragonFly specific things in it. This should

1. be always applied regardless of architecture,
2. live as individual patch files under files/ (like before) instead of as one big patch.

We can use gcc7 or 8 or X to build lang/rust, only the bootstrap requires gcc8

(On Diff #53956)

it's a noop for amd64 and dfly, I'm just moving c_char elsewhere.

Ah, ok.

Can you amend the comment with something like "The bootstrap is hardcoded to use gcc8, but we can build with a newer or older compiler as provided by USE_GCC=yes" ?

Then it should be no problem to always apply it everywhere.
