  Can't find libusb pkg: Could not run `"pkg-config" "--libs" "--cflags" "libusb-1.0"`
  The pkg-config command could not be found.

  Most likely, you need to install a pkg-config package for your OS.

  If you've already installed it, ensure the pkg-config command is one of the
  directories in the PATH environment variable.

  If you did not expect this build to link to a pre-installed system library,
  then check documentation of the libusb1-sys crate for an option to
  build the library from source, or disable features or dependencies
  that require pkg-config.

  thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 3, kind: NotFound, message: "The system cannot find the path specified." }', libusb1-sys\build.rs:108:6
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

however I have pkg-config and other crates are able to be installed that use it, e.g, gcov

$ which pkg-config
/usr/bin/pkg-config
$ pkg-config --version
1.8.0

Note that the cygwin path C:\Cygwin\bin is NOT, and should not, be in the windows System PATH environment. This is normal for cygwin installations. pkg-config however IS in the Cygwin path, as above.

$ uname
CYGWIN_NT-10.0-19044

Windows 10 x64 + Cygwin x86_64.

I'm here because I'm trying to build probe-run which uses libusb 0.5 as a dependency which also fails to build for a different, but related libusb reason, see knurling-rs/probe-run#325

[a1ien]

I not recommend use cygwin for building library. For windows better try vcpkg. And also in cygwin really outdated packages. libusb 1.0.21 it's released around 2016 year.

[hydra]

whilst I agree that some cygwin packages are old, I don't really want yet another package manager to install, maintain and update on all the projects development machines. Also, the prerequisites for vcpkg list Visual Studio 2015 or newer, I don't fancy having to install and maintain another IDE either, the project already uses CLion and Eclipse.

I'm also not sure about compatibility between vcpkg compiled packages and the rest of the tools and ecosystem. This is why I don't build on WSL which is binary incompatible.

I'll look at vcpkg, I'd never heard of it before, but if you have other suggestions or solutions that would be preferred, keep me posted.

[a1ien]

1. vcpkg it's recommend package manager for windows by Microsoft. They develop and maintain in.
2. You don't need install Visual Studio ide you just need msvc compiler, Visual Studio C++ Build Tools if be more correct.
3. For building rusb(and libusb1-sys) you only need compiler. If libusb1-sys didn't find any suitable libusb version they build from vendored source code. But you need only compiler, for example the msvc and not cygwin.

If you setup rust fro windows for use msvc then you have less problems. The msvc compiler is free for use.

P.S. cygwin it's crutch try avoid it in all place where it's possible. For use rusb they not need entirely.
P.S.2 Rust and cygwin don't work well together.

[a1ien]

If you want build with gcc staff a suggest use MSYS2.
