Vit*_*aev 7 packaging debian repository deb
我需要构建一个依赖于特定版本的第三方库的项目：
? cat debian/control
Source: libhole-cpp
Priority: optional
Maintainer: Vitaly Isaev <isaev@embarce.ro>
Build-Depends: debhelper (>= 9), cmake,
flatbuffers (= 1.2.0-1),
libboost-dev,
libboost-system-dev,
catch
Standards-Version: 3.9.5
但是，flatbuffers我们的 repo 中有几个包，包括较新的包：
? 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

任何人都可以澄清我的构建工具链有什么问题吗？操作系统是 Ubuntu 16.04。
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
该解决方案与 Johannes Schauer 的解决方案的不同之处在于……
apt-cudf-get而不是apt-get-o APT::Solver::Strict-Pinning=false-o APT::Solver::aspcud::Preferences="-new,-removed,-changed"-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）debian-devel 邮件列表线程索引“mk-build-deps 无法安装特定版本的 Build-Depends 软件包”：https://lists.debian.org/debian-devel/2016/08/threads.html#00442
