I'm trying to update our Rust.  I've got it to work further than the text "package bootstrap" once, but I can't find how I did it anymore.  See below.

Help?

Could you tell us what you’ve tried and what the error means?

Hi,

Rust as I posted it fails with the text below.  It tries to compile and link rustc via bootstrap rustc and gcc, via a i686 compiler (also on x86_64).  What the error message means is that it is only picking up the x86_64 glibc - and not the i686 glibc - even though the "cc" command line contains "-m32".  I've even added a custom linker command to the rust config (also in the patch) but that doesn't help either - apparently that setting is not even picked up.  Maybe that's the reason... 

Rust has support for Nix somewhat, and I've enabled it in the bootstrapper.  I've also added cross-libc for i686 and fixed up environment variables (in a hacky way - maybe that's the reason).

So I guess my actual question is how to do this cross compilation correctly.  Note that the rust bootstrap compiler are binaries from upstream.  (There's a project "mrust" <https://github.com/thepowersgang/mrustc> that is a reimplementation of Rust in C++ that we could use in the long term in order to remove this binary)

Aha!  I digged some more and found that rust-bootstrap doesn't specify #:system "i686-linux", while rustc-bootstrap does.

Symptom:

$ guix environment --pure rustc
[env]$ ls -l /gnu/store/15hcgm941wgxfk08w0wrwpd9p7wjbq87-profile/bin/cc

Note "x86-64".

On the other hand:

[env]$ file -L /gnu/store/15hcgm941wgxfk08w0wrwpd9p7wjbq87-profile/bin/rustc
/gnu/store/15hcgm941wgxfk08w0wrwpd9p7wjbq87-profile/bin/rustc: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /gnu/store/kzkgc8avgnanrv3ab2g3g8yj7l4bcavj-glibc-2.25/lib/ld-linux.so.2, for GNU/Linux 2.6.9, not stripped, with debug_info

Note "32-bit", "80386".

But when I change rust-bootstrap to specify #:system "i686-linux", then I get:

And gcc picks up ld from PATH, which is a x86_64 ld.  Bad.

Do we support lib32 a la "gcc -m32" ? How can we provide a working glibc for that? It seems that rustc bootstrap is trying to use that option.

Note that the rust bootstrap compiler are binaries from upstream.
(There's a project "mrust" <https://github.com/thepowersgang/mrustc>
that is a reimplementation of Rust in C++ that we could use in the long
term in order to remove this binary)

In the long term this would be nice. It was my first idea when
I learned about this project, but as you can read in the
bug I opened in the last 2(?) months in the mrustc bugtracker
it still requires rustc to work.

We don’t support multilib, so glibc provides only 64-bit headers on
x86_64 (if you try -m32 there you’ll get an error about missing
<gnu/stubs-32.h> or something like that.)

At GPCE I also talked with someone who implements a compiler for a
Rust-like language (Rust with some extensions, minus a few features, so
not directly usable but might be worth keeping in mind):

Yeah.

What happens when I use an i686 host/target gcc and use "-m32" (rustbuild does that)? Will it just ignore the option?

Yes, I think -m32 is a no-op in this case.

Hi Ludo,

> Yes, I think -m32 is a no-op in this case.

Yep.  I just got rustc to build a bootstrap executable (which fails when executing it [*], but hey, progress) by making a union-build with all the i686 libs.

Feels kinda icky, but it seems that propagated-inputs don't remember the #:system it was for, so for example if A propagates B and A specifies system i686, and X specifies system x86_64 and X depends on A, then X's B will be x86_64.  Weird but understandable I guess...

Details:

A:
  propagated-inputs
    B
  arguments system i686

X:
  native-inputs
    A
  arguments system x86_64

Now X's B is x86_64...

The workaround is this:

A:
  arguments system i686
  native-inputs
    B
  union-build out/lib from B (etc)

X:
  native-inputs
    A
  arguments system x86_64

That works.

In our specific case A = "rust-bootstrap", X = "rustc", B = "glibc", "gcc:lib" etc.

[*] Tries to load libgcc_s.so.1 from the glibc store directory.  WTF?

Hey Danny,

what's missing here? rustc has been released as 1.22.1 since this thread
started. I hope to introduce some people in January at our GNUnet
workshop to the open tasks on the Guix rust-build-system and - depending
on how they judge their own abilities - get them to work on this throughout
the year.

Hi ng0,

I've attached the current version of gnu/packages/rust.scm .

For some reason, Rust bootstrap ignores the environment variable AR_x86_64_unknown_linux_gnu even though it doesn't ignore other similar variables (CC_x86_64_unknown_linux_gnu etc).  It also ignored config.toml's [target.x86_64-unknown-linux-gnu].  Therefore, the bootstrapping fails when trying to compile the x86_64 version (the i686 version works).

To try it, copy the attached file to gnu/packages/rust.scm , overwriting the latter file.

Then just invoke

$ ./pre-inst-env guix build rustc

It will fail like explained above, with the log message:

------------------------------------------------------------------------------------------------------

I've had something similar before - see CFG_LOCAL_RUST_ROOT substitution in rust.scm - but I thought I fixed it.

So the next step would have someone find out why it doesn't pick up the value from the environment variable "AR_x86_64_unknown_linux_gnu".
