Hey @ravensnowbird, this looks like a symptom of the same problem described in #404.

[ddcprg]

is there a workaround for this issue? I'm trying to compile with GitHub actions for x86_64-unknown-linux-musl and I get the same error. The pipeline file is below

on: [push]

name: Alpine build

jobs:
  linux_alpine:
    name: Linux Alpine
    runs-on: ubuntu-20.04
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Prepare Rust toolchain
        uses: actions-rs/toolchain@v1
        with:
          toolchain: stable
          target: x86_64-unknown-linux-musl
          override: true
      - name: Compile debug
        uses: actions-rs/cargo@v1
        with:
          use-cross: true
          command: build
          args: --target x86_64-unknown-linux-musl

@ddcprg I believe the workaround is documented here #149 (comment)

[Alexhuszagh]

I would also assume the images don't have libdbus-1-dev installed by default, so you'd have to extend an image with your own packages as a result. I'll be adding an example on the Wiki on how to integrate pkg-config with cross.

[Alexhuszagh]

With #727 we've added the PKG_CONFIG_PATH to all *-linux-gnu images, so adding external packages is now documented and pkg-config support is enabled by default.
