rust-1.86.0_beta fails to compile in offline mode

[stefson]

hey everyone,

I just downloaded the rust-1.86.0_beta tarball, unpacked it and compiled it.

Sadly, the build fails to compile with this error:

please be so kind to allow an offline build, thank you!

[jieyouxu]

What's the exact invocation you used to build? Are you trying to build a dist tarball from the dist tarball?

Maybe related to #130099?

[ehuss]

I haven't tried, but I imagine this is fixed by #137020, and could maybe use a backport?

[jieyouxu]

Oh right. #137020 is beta-accepted but not yet backported.

[stefson]

yes, I saw that one too - it was just nominated for beta backport.

so maybe just put this on hold, and wait for the backport getting merged?

still, my config.toml for completeness:

[jieyouxu]

In the meantime, if you don't need to vendor deps for dist build, you could try setting

[dist]
vendor = false

[jieyouxu]

I'm going to reopen #136955 to track the beta-backport, and close this as a duplicate of #136955 (yes, your invocation indeed fails at generate-copyright). Thanks for the report.

[stefson]

@jieyouxu the diagnosis is correct, I backported #137020 locally and it build just fine in offline mode:
