I tried to compile, but firstly I have to disable Vala-Lint as the developer of Akira has recommended.
What draws my attention is a topic in the which Mac user asked the same developer of Akira to expand the version for Mac, but he refused. It is very good that he does not sell himself and that it remains exclusive for Linux. He also thought of donation in his README. So the opportunistic companies, like Adobe, Corel, etc. will give up because they are not interested in Linux.
