We include some native support for C/C++ libraries. This should be "well designed", but ideally would scale up to supporting very support complex projects (like `swiftc`). I care about this part deeply because there is a lot of awesome stuff I want to do in llbuild + clang, and that depends on being able to get the project onto those tools. We will by necessity need to start with a small limited scope and feature creep our way forward.</div><div><br class=""></div><div>2. We provide an adaption mechanism, to allow projects that can't yet be built by #1 to still integrate directly into the ecosystem. This can take two forms:</div><div><br class=""></div><div>2.a. For projects which *could* conform to #1, but the only problem is the upstream project doesn't want to change (or hasn't yet), then we could support an adaption mechanism which just took in the upstream project and overlayed the appropriate Package.swift definitions that we need to use to build it. This means that swiftpm + llbuild would have a full understanding of the build process, which is the ideal scenario for the ensuring a good user experience.</div><div><br class=""></div><div>2.b. For projects which are just "too complicated" to do #2.a, we would allow a form of your #3 (a shell script which downloads and builds). The way I envision this working is that:</div><div>- I'd like to avoid the script actually downloading anything, I think we should still try and use our model for pulling the sources. This may mean someone maintains a tagged version of an adaptor package that includes the source of the upstream project + the adaptor pieces.</div><div>- We would require a very strict interface between that script and the rest of the package manager. Essentially, we would provide the script with its inputs, and we would expect it to produce, as an output, the exact kind of build layout that we ourselves would have done for project in case #2.a. In practice, those scripts would usually look something like " configure && make && ... move the built products around a bunch to conform to the expected layout ...". We would run the script in appropriate dependency order, then ingest / audit all of the outputs, and from then on it would integrate just like #2.a.</div><div><br class=""></div><div>We need to be very careful about doing #2.b in a way that doesn't restrict our ability to evolve...</div><div><br class=""></div><div>One thing I would like to call out is that I don't feel like we need to directly support the total amount of complexity that exists in the world w.r.t. C family projects. I want use to help make the world more sane by coming up with sensible conventions and models for C family projects, and then apply pressure in other places to reduce unnecessary complexity or to converge on semi-standard solutions. I outlined a bit more of my philosophy here in:</div><div> <a href="https://lists.swift.org/pipermail/swift-build-dev/Week-of-Mon-20151130/000027.html" class="">https://lists.swift.org/pipermail/swift-build-dev/Week-of-Mon-20151130/000027.html</a></div><div><br class=""></div><div><blockquote type="cite" class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div class=""><div class=""><br class=""></div><div class=""><blockquote type="cite" class=""><span class="" style="font-family: HelveticaNeue; display: inline !important;"> (and if you give me pointers to the full tree I would be interested in checking them out as test cases), this feature may be enough that you could in theory get your Swift package to also build the necessary C libraries (with some adaption work).
