Source: akonadi-search Version: 4:24.12.3-1 Tags: patch User: debian-cr...@lists.debian.org Usertags: ftcbfs X-Debbugs-Cc: debian-cr...@lists.debian.org, debhel...@packages.debian.org, nil...@debian.orgakonadi-search fails to cross build from source, because it builds a Rust-based component for the build architecture. It's a CMake package in principle and uses corrosion (a CMake recipe for integrating a Rust crate into a CMake project) to have part of its source be implemented in Rust. And here comes the catch. Corrosion cannot detect the Rust architecture from other CMake variable and needs to be told via Rust_CARGO_TARGET. Nothing sets this and hence akonadi-search fails to cross build. Now the attached patch simply sets that variable from debian/rules, but this is a generic problem that likely affects all (4) reverse dependencies of corrosion. The question arises whether something else should be setting this variable anticipating more widespread adoption of corrosion. Any thoughts? Helmut
From a build system maintainer PoV, I am happy to pass that option to cmake. However, currently the tooling (debhelper and debputy) only has infrastructure for `dpkg-architecture` provided flags and this value seems to come from rustc.
The easiest for me would be if this logic moved to `dpkg-architecture` but I am unsafe if the `dpkg` maintainers want to maintain these flags going forward.
Best regards, Niels
