timIt's been a while since my last Rust blog post. The latest thing that's happened is that I just submitted a pull request that gives rustpkg packages that have custom build scripts the ability to have C dependencies (or, in fact, dependencies on any sort of artifact that you can write a Rust program to build). There's no magic here -- in fact, for the most part, it's just a matter of writing an example to show what needs to be done. Someday there will be a higher-level interface to rustpkg where you can just declare some source file names and rustpkg will do the rest, but not today. In the meantime, the build script explicitly sets up a workcache context and declares foreign source files as inputs, and so on.
The thing I did have to change in rustpkg itself was changing the install_pkg function (in the API that build scripts can call) so as to take a vector of extra dependencies. Currently, the types of dependencies supported are files (any source files, which get checked for freshness based on hashing their contents and metadata) and binaries (any files at all, which get checked for freshness based on their modification times).
Completing this bug means that (once it's reviewed and merged) I'll have completed the "build all of Servo" milestone for rustpkg, and on time, no less (albeit with less than 30 minutes remaining). Jack has been steadily working on actually building Servo with rustpkg, discovering many issues in the process, and once this pull request is merged, we should be able to do the rest.
