From the readme:
Dependencies
If you are compiling on Linux make sure to install the following dependencies:
Ubuntu
$ sudo apt install libasound2-dev libx11-xcb-dev libssl-dev

If it still doesn't work after, let us know and we will reopen the issue.

I have install the dependencies before compile
the Ubuntu is virtual machine Is that the reason compile failed? @jojolepro

The error seems to be because you don't have alsa installed, but even if you would be able to compile the current renderer doesn't support virtual machines because it requires a physical gpu (or integrated gpu) to work properly. If you get it to compile it will complain about no virtual pixel format.
