Cross-compilation libudev-sys

[xoac]

Hi, I have a problem with cross-compile example tokio-serial. I described the problem on tokio-serial issue - but I think here should be more people that can manage this problem.

[messense]

Try it with apt-get update && apt-get install -y pkg-config && YOUR_COMMAND

Hi, thx for quick response. Here is the result:

To learn more, run the command again with --verbose.

So the problem is that I don't have libudev library for armv7. (what is more linked statically).

Look here. Maybe I should ask this question there..

[xoac]

I added here a wrong output (form my crate). But I go one step ahead if u are interested see here

[theronic]

@xoac did you manage to solve this? I'm having the same problem trying to cross-compile a project using serialport crate.

[xoac]

@theronic Yes. You have a links above. It go to crate that was responsible for that:

See: https://github.com/berkowski/tokio-serial/issues/13#issuecomment-427592411

if u wanna use serialport crate in version 2 u can use my PR: https://github.com/xoac/tokio-serial/tree/serialport_rs_2_3_1
