Debian 打包：mk-build-deps 无法安装特定版本的 Build-Depends 软件包

我需要构建一个依赖于第三方库的特定版本的项目：

➜  cat debian/control 
Source: libhole-cpp
Priority: optional
Maintainer: Vitaly Isaev <[email protected]>
Build-Depends: debhelper (>= 9), cmake, 
    flatbuffers (= 1.2.0-1),
    libboost-dev,
    libboost-system-dev,
    catch
Standards-Version: 3.9.5

但是，我们的存储库中有几个flatbuffers软件包，包括较新的软件包：

➜  apt-cache policy flatbuffers
flatbuffers:
  Installed: (none)
  Candidate: 1.4.0-17
  Version table:
     1.4.0-17 500
        500 http://repo12.mailbuild-2.embarce.ro xenial/local amd64 Packages
     1.2.0-1 500
        500 http://repo12.mailbuild-2.embarce.ro xenial/local amd64 Packages

在这种情况下mk-build-deps拒绝安装所需版本的软件包：

➜  sudo mk-build-deps --install debian/control

谁能澄清我的构建工具链有什么问题吗？操作系统是Ubuntu 16.04。

答案1

太长不看；

aspcud通过以下方式委托给求解器apt-cudf-get：

mk-build-deps \
    --install \
    --remove \
    --tool \
    'apt-cudf-get --solver aspcud -o APT::Get::Assume-Yes=1 -o Debug::pkgProblemResolver=0 -o APT::Install-Recommends=0' \
    debian/control

解释

该解决方案不同于约翰内斯·绍尔的在那里面...

  • 它使用apt-cudf-get而不是apt-get
  • 它省略了以下选项（在我的测试中不起作用）：
    • -o APT::Solver::Strict-Pinning=false
    • -o APT::Solver::aspcud::Preferences="-new,-removed,-changed"
  • 它添加了以下选项：
    • -o APT::Get::Assume-Yes=1（以非交互方式安装软件包）
    • -o Debug::pkgProblemResolver=1（mk-build-deps --tool默认）
    • -o APT::Install-Recommends=0（mk-build-deps --tool默认）
