Can not compile an application on 0.3.5

[yuvalalon510]

On my Debian 10.9 Buster stable system a macroquad 0.3.5 application does not compile using cargo run.
I tried macroquad 0.3.4 a few weeks ago and it worked. However, it doesn't work right now.

error: aborting due to previous error

Maybe it is libasound2-dev system package missing?

[not-fl3]

And there may be something in the error, could you post the whole error message?

[yuvalalon510]

libasound2-dev is installed
