It seems the libclang-dev package does not install a libclang.so symbolic link, you have to be explicit about which version you want, e.g. libclang- 6.0.so on my Debian Sid installation.

I use dpp to generate d code to import:
- Create a temp.dpp file with #include inside
- Run "d++ --preprocess-only temp.dpp"

Now you have your .d file exactly like in dstep.

So where does this leave DStep if DPP is the next generation tool?

Of course I can create a dstep executable, but cannot yet create a d++ executable on Debian Sid. :-(

True. And indeed Fontconfig can mostly meet the "it's an opaque type based system" but there are a few dark corners – most of which I need!

Not good enough to be honest, D is a statically typed language and so all usage of functions should be checked against something other than a human guess.

Anyway DStep has given me a Fontconfig D module that works nicely, and I will
check dpp as an alternative as soon as it builds on Debian Sid.
