Can you post the build output with the error, please?

I don’t have the exact error, but the problem was a -Werror=missing-template-arg-list-after-template-kw error in GRPC. Adding build:clang --cxxopt=-Wno-missing-template-arg-list-after-template-kw allowed the build to succeed.

Ok thanks. Envoy toolchain is still on clang 18 so you need to patch your build config until we upgrade the toolchain to newer versions. Alternatively you can upgrade Envoy toolchains.

How do I upgrade Envoy toolchains? Given that Envoy is not packaged in distributions, I think it would be best for Envoy to buildle its own hermetic toolchain, which would either be downloaded and checked against a specific hash (default) or bootstrapped from source. Additionally, the documenation should be updated to reflect that one must use the toolchain Envoy provides, rather than a system toolchain.

absolutely agreed - see #39010 - this has been discussed for a long time, but i think we are pretty close to actually implementing it
