错误 # args: 应该是“_o3 self class proc file optx opty”

Posted 2023-02-18

【中文标题】错误 # args: 应该是“_o3 self class proc file optx opty”

【英文标题】：wrong # args: should be "_o3 self class proc file optx opty"

【发布时间】：2021-10-04 09:12:48

【问题描述】：

我在运行tcl代码时，出现如下错误：

错误的#args：应该是“o3 self class proc file optx opty” （模拟器 namtrace-all-wireless line 1） 从内部调用 "$ns namtrace-all-wireless $namtracefd" （文件“test1.tcl”第 26 行）

我应该如何修改我的 tcl 代码以使程序正确运行。

这是tcl文件中的代码脚本：

【参考方案1】：

错误的#args：应该是... optx opty

几个错别字之一：原来的第26行应该是$ns_ namtrace-all-wireless $namtracefd $opt(x) $opt(y)

NAM 抱怨“未定义节点 6”。建议：将 nn 编辑为 7 个节点。
