Failed to compile with cargo build

[KyleIm]

Hello. I am trying to compile your xbnet rust file using cargo build. However, whenever I try it I have error and not able to compile it.

Here are the error message which I found.

error: failed to run custom build command for `libudev-sys v0.1.4`

Caused by:
  process didn't exit successfully: `/home/hea/xbnet/xbnet-master/target/debug/build/libudev-sys-8d68dca4efa28bce/build-script-build` (exit status: 101)

First, I thought it would be missing libudev-sys v0.1.4 and I installed it by using 'sudo apt install libudev-dev'. (The package is installed with latest version.) However, I still see the same error when I try to use cargo build. Is it the problem with the version of libudev? Or am I missing something?

Thanks in advance

Hi,

When building from source, you need to have certain dev packages installed. You may need to apt-get install pkg-config.

If you run the command from the error message:

pkg-config --libs --cflags libudev

that may clarify what the problem is, but I'm guessing you need to install pkg-config.
