I try build Oni2 on ubuntu 16.04, it is failed, but build it on ubuntu 18.10 is ok.

[jplew]

I'm getting this exact error when building on Ubuntu 18.04. Besides upgrading to 18.10, can you think of any other solution?

[jplew]

nevermind. From the README:

NOTE: reason-fontkit (a dependency of revery) requires harfbuzz 1.7.7+. This means revery requires Ubuntu 18.10+ (or you can install libharfbuzz-dev@1.8.8 by adding 'cosmic' packages to your sources, but proceed with caution since you can break other packages this way)

NOTE: If esy build produces an error about libpangoft2 then try deleting the ./_esy and ~/.esy directories and run run esy install and esy build again.

I ended up updating my WSL Ubuntu installation using this guide:
