我正在尝试使用coq从frama-c WP插件教程运行swap.c示例，但我收到BuiltIn.v文件的以下编译错误;
$frama-c -wp -wp-rte -wp-proof coq swap.c

版本; Frama-c Magnesium-20151002，Coq 8.5，OCaml 4.02.3
根据frama-c网站的说法，8.4+应该没问题，但我认为不是！ 问题是Coq的版本（我认为）。
WP插件教程列表-wp-coq-opt选项，用于传递coqc选项。所以我试着跟随;
frama-c -wp -wp-rte -wp-proof coqide -wp-coq-opt="-compat 8.4" swap.c
[kernel] user error: option `-wp-coq-opt=-compat 8.4' is unknown
没用！对此有何解决方案？
