I haven't been able to get dpp to build. I've discovered that the problem is with libclang. It installs, but when running the tests, I get the lengthy message below. Obviously I need to install something (running Ubuntu 16.04) but I've got numerous libclang related packages installed already and have no idea what that could be. What dependency am I missing?

Found the problem. The libclang package is looking for /usr/lib/llvm-3.9/lib/libclang.so. For some reason, Ubuntu has libclang.so.1. Creating a symlink in that directory to libclang.so is a solution.

Do you have the development package (probably something like libclang-3.9-dev) installed ? Usually they are the ones containing the correct symlink (see https://forum.dlang.org/thread/ea9432f8d37a563bc4920d0bb8748ae7ab23dfd4.camel@winder.org.uk)

Yeah, I didn't need the symlink on a different machine with Ubuntu 18.04. After some digging around, I found that I had libclang1-3.9, libclang-dev, and libclang-common-3.9-dev installed. libclang1-3.9 installs libclang.so.1. The one I was missing was libclang-3.9-dev.

It's confusing and I think this could be handled better by the distro. But this is also one of the reasons I'm not a fan of dub. The user is left to sort through these dependencies themselves, and that means it's really not suitable for packages that link to C code (which is most of what I do). One of the main selling points of D is its C interoperability, but a lot of new users would walk away rather than trying to figure this out, concluding that D is buggy.

I don't think it's confusing, you will also need to install the development package if you are coding something in C. It's the same, except for the language being D instead of C. As D is advertised as a systems programming language, this doesn't seem confusing (to me, at least).

If a dub package uses a system library though, it can be hinted at by the `systemDependencies` key in `dub.json`/`dub.sdl`. The problem is, I don't think many packages actually use it and I agree that since it's too easy to overlook it, you're often left to figure everything out. It's not something you're likely to find out unless you are already looking for it.
