Fails to build with GCC 15

[sergiodj]

Hi,

I'm filing this issue to let you know that vector is currently FTBFSing with GCC 15 (development version, snapshot from 20250411).

It's currently being affected by two problems:

• Fails to build with GCC 15 MaterializeInc/rust-krb5-src#28
• Fails to build with GCC 15 rust-onig/rust-onig#191

I'm attaching the full build log here just in case.

vector-0.46.1-r0.log

Thanks.

Hi @sergiodj I noticed this too. vrl is the one depending on rust-onig through grok crate. I updated grok to 2.1.0 in vectordotdev/vrl#1420 to fix vrl compilation.

I think rust-krb5-src may be a little more problematic to fix...

As a workaround, I think I will use CC=gcc-14 cargo build 😄

FYI krb5-src has been abandoned and archived. I don't think we'll see a fix coming from that direction.

See #24208 (comment)

The "fix" here is that we unfortunately have to wait for the folks at rdkafka to add sasl support some other way. Only then can we bump rdkafka's version and close this.
