Ahh I see what you mean -- I was more thinking about the library issue, but yeah building is definitely still really hard. I think good support for unikernels is a long time off, and will obviously vary by language -- maybe the usage that finally breaks through will be tight integration with some lower level compile tools. For example if a company were to hit GraalVM (which is really trying to push themselves as the better-than-stock VM for a bunch of languages) and LLVM as integration points for unikernels I think they could really make a convincingly easy toolchain (without modifying developers' current toolchains).
