如何向ntpd添加选项
提问于 2022-02-25 06:43:18
我想在ntpd中添加一个新的选项，但是在向ntpd/ntpd-opts{.c, .h}添加了一些行之后，我找不到如何生成ntpd/ntpdbase-opts.def。
$ git diff ntpd/ntpdbase-opts.def
diff --git a/ntpd/ntpdbase-opts.def b/ntpd/ntpdbase-opts.def
index 66b953528..a790cbd51 100644
--- a/ntpd/ntpdbase-opts.def
+++ b/ntpd/ntpdbase-opts.def
@@ -479,3 +479,13 @@ flag = {

};

+ value = F;
+ arg-type = number;
+ descrip = "Some new option";
+ doc = <<- _EndOfDoc_
+ For testing purpose only.
+ _EndOfDoc_;
+};你有什么想法吗？

它只是在构建脚本中。只需正常编译https://github.com/ntp-project/ntp/blob/master-no-authorname/INSTALL#L30，并将其取出来。

除了@KamilCuk的回答之外，我们还需要执行以下操作来添加自定义选项：
- 编辑
*.def文件 - 运行
bootstrap脚本 - 运行
configure脚本具有--disable-local-libopts选项H 210H 111Run make>H 212G 213
例如,
$ git diff ntpd/ntpdbase-opts.def
diff --git a/ntpd/ntpdbase-opts.def b/ntpd/ntpdbase-opts.def
index 66b953528..a790cbd51 100644
