bootstrap is broken for all custom targets on rust-1.85.0_beta #137064

stefson · 2025-02-15T07:29:09Z

hello everyone,

I've been using a custom target for my locally built rustc toolchain for many years now, the target is added with a custom patch and everything has been working just fine:

rustc 1.84.0 (9fc6b4312 2025-01-07) (built from a source tarball)
binary: rustc
commit-hash: 9fc6b43126469e3858e2fe86cafb4f0fd5068869
commit-date: 2025-01-07
host: armv7a-unknown-linux-musleabihf
release: 1.84.0
LLVM version: 19.1.5

rustc --print target-list | grep armv7a-unknown
> armv7a-unknown-linux-musleabihf

with the branching of the 1.85.0_beta branch, the already built-in target of the local rustc-1.84.0 binary cannot be found anymore by the bootstrap process:

Can you check if setting BOOTSTRAP_SKIP_TARGET_SANITY=1 make it work?

stefson · 2025-02-15T08:43:02Z

like this?

onur-ozkan · 2025-02-15T10:37:32Z

You should use bootstrap scripts (x or x.py) instead of bare bootstrap binary.

ok, so here is the result of

so that doesn't make any difference, I'm afraid.

arachsys · 2025-02-20T23:42:12Z

I'm seeing this too on the now released rust-1.85.0, with (longstanding) {aarch64,x86_64}-$VENDOR-linux-musl targets added in compiler/rustc_target/src/spec/targets/ and in the table in compiler/rustc_target/src/spec/mod.rs. The custom target worked fine up to and including rust-1.84.1, but aborts on bootstrap with rust-1.85.0.

(To preempt worries that targets/*-$VENDOR-linux-musl.rs are invalid, I can reproduce when they are literally a copy of the corresponding *-unknown-linux-musl.rs. Nowadays my vendor target's only difference is to remove the incorrect static-link default on my native musl system, so there's nothing tricky going on.)

A bit of println!() debugging suggests we fail on

let compiler = cfg.get_compiler();

of find_target() in src/bootstrap/src/utils/cc_detect.rs.

Explicitly specifying cc = "/bin/cc" etc. in the target section of config.toml doesn't change this behaviour, and strace suggests bootstrap execs rustc --version --verbose to get the target name, but never tries to run cc, c++, ar, etc.

arachsys · 2025-02-21T00:19:48Z

This seems to be related to the cc-rs mistake discussed in rust-lang/cc-rs#1317 - this introduced a hard-coded list of targets (!!) which broke custom rust packaging on Alpine Linux, Chimera Linux and others, though it hadn't made it all the way out to break a 'stable' rust release at the point they all reported it.

The bootstrap build works fine if you bodge the hard-coded list in the vendored cc crate:

arachsys · 2025-02-21T10:59:53Z

Ah, sorry to hear that - possibly something about the way I build rust allows this to work for me and not for you? My build recipe is at https://github.com/arachsys/packages/tree/master/rust and you can see the diff I needed to get the 1.85.0 release tarball building (with both 1.84.1 and itself) at arachsys/packages@7596f3fac1. (The only relevant bit of that diff for you is probably the change to target.diff, and I can't see anything that might make me too 'unusual' in the build script itself.)

One thing I didn't think of last night: you'll definitely have to work around the ridiculous file checksums if you patch vendor/cc-* in the source tree with upstream cargo. You can just remove the entire "files" key from them with sed:

sed -i -E 'H;1h;$!d;x;s/("files"\s*:\s*\{)("([^"\\]|\\.)*"|[^"}])*/\1/' vendor/*/.cargo-checksum.json

or disable this (deliberately user-hostile) behaviour altogether with something like arachsys/packages@bdc6635b5e.

heitbaum · 2025-02-22T14:27:11Z

How are we progressing with a fix for this build issue?

onur-ozkan · 2025-02-22T21:28:34Z

Can you downgrade bootstrap cc to =1.1.22 and check if it works? I hope other versions of cc from compiler and library tree will not effect this.

bcressey · 2025-02-22T22:05:00Z

@stefson the generated list is searched via binary search:

generated::LIST.binary_search_by_key(&target_triple, |(target_triple, _)| target_triple)

So any new entries you add need to be in sorted order - your armv7a-unknown-linux-musleabihf target should not come before armv7-unknown-linux-musleabihf.

I did the same thing when adding my *-bottlerocket-linux-* targets and it took me a while to track down.

(Thanks @arachsys for the patch!)

heitbaum · 2025-02-22T22:42:27Z

I can confirm that this patch does allow the build of bootstrap to complete.
