Cross-building rust 1.83.0 on & for NetBSD failure #133629
Open
Description
I am doing my best to try to keep the various NetBSD targets for rust working.
As part of that process, I am cross-building binaries from x86_64 to most of the
other targets, and carry out testing of the results, for some of the targets this involves
self-hosting the rust compiler.
I have two new observations for rust 1.83.0 (1.82.0 works fine):
- A new seemingly-non-fatal error message which is difficult to get a grasp on has started appearing in the build log:
1.288127806s INFO prepare_target{force=false package_id=sysroot v0.0.0 (/usr
/pkgsrc/wip/rust183/work/rustc-1.83.0-src/library/sysroot) target="sysroot"}: ca

Caused by:
No such file or directory (os error 2)
There are many such instances. Testing for the existence of the quoted file name afterwards does not reproduce the problem(!)
Looking for the file afterwards shows that it exists:
$ find work -type f -name lib-sysroot

- While natively building the rust compiler on x86_64 works fine, and the resulting compiler also works, I get a new (to me) problem while cross- building the rust compiler, in this first instance for our
armv7hftarget:
using sysroot /usr/pkgsrc/wip/rust183/work/rustc-1.83.0-src/build/x86_64-unknown-netbsd/stage1

but apparently, this particular rustc instance isn't being pointed in the right direction.
It is also somewhat unclear to me whether this second problem is related to the first issue listed above.
My initial build attempt was done with -j 32 (I have the resources for it), but repeating it with -j 1 to root out whether this is a bug related to parallelism of the build reveals that the answer to that question is "no".
I expected to see this happen: Cross-building the rust compiler ought to succeed.
Instead, this happened:
The build errored out with
