Question

我一直想要使用coq-vpl，我安装了它。我可以从opam list

确认一下

ubuntu@ubuntu-xenial:~$ opam list
# Installed packages for system:
...
coq                    8.6  Formal proof management system.
coq-vpl                0.2  Coq interface to VPL abstract domain of convex polyhedra.
coq-vpltactic          0.2  A Coq Tactic for Arithmetic (based on VPL).
coqide                 8.6  IDE of the Coq formal proof management system.
...

但是，如何找出实际调用的库以及需要导入的内容？ vpl页面上没有文档。

Answer 1

你可以运行

coqc -config

获取配置变量列表。在我的系统上，这给出了

LOCAL=0
COQLIB=/home/jgross/.local64/coq/coq-8.7.1/lib/coq/
DOCDIR=/home/jgross/.local64/coq/coq-8.7.1/share/doc/coq/
OCAMLFIND=/home/jgross/.opam/system/bin/ocamlfind

如果查看user-contrib给出的路径的COQLIB目录，您应该看到包含已安装的各种库的文件夹。对于任何这些文件夹名称，您可以将From FolderName Require Import FileName添加到Coq文件中。

Answer 2

根据https://github.com/VERIMAG-Polyhedra/VplTactic，您需要运行coq，例如通过启动coqide（您已安装）并在左侧窗口中键入以下行并执行它们（使用窗口顶部的向下绿色箭头。）

Require Import VplTactic.Tactic.
Add Field Qcfield: Qcft (decidable Qc_eq_bool_correct, constants [vpl_cte]).

依此类推，请阅读上面给出的链接页面。我还没试过。
