I need the libboost-all-dev package installed to build my C++ project

[ClausKlein]

If it is not available, I try to fetch and build it.

But this fails with a strange error:

cmake --preset gcc-release --log-level=VERBOSE  # --fresh

This is a known issue with Boost’s .7z release packages — they contain UTF-16LE encoded filenames, and CMake/libarchive on
most Linux distros does not support 7-Zip’s Unicode filename encoding correctly.

I would be great if the libboost-all-dev package would be installed as default.

First I wand to thank you for preparing this docker images!

As a workaround I install boost within my workflow:

name: Clang

on:
  push:
    branches: [ main, develop ]
  pull_request:
    branches: [ develop ]
  workflow_dispatch:
  schedule:
    - cron: '30 15 * * 6'

jobs:
  clang:
    strategy:
      fail-fast: false
      matrix:
        version: [20, 21]

    runs-on: ubuntu-latest

    container:
      image: ghcr.io/mattkretz/cplusplus-ci/clang${{ matrix.version }}

    steps:
      - uses: actions/checkout@v4

      - uses: actions/setup-python@v5
        with: { python-version: "3.13" }

      - name: Install Boost
        run: apt-get update && apt-get install -y libboost-all-dev || echo ignored

      - name: Setup Cpp
        uses: aminya/setup-cpp@v1
        with:
          # compiler: llvm-${{ matrix.version }}
          cmake: 4.1.2
          ninja: 1.13.0
          gcovr: true

      - name: Run test suite
        env:
          CXX: clang++-${{ matrix.version }}
        run: |
          export PATH=$HOME/.local/bin:$PATH
