未知的日志格式字符“<”

Question

在 Ubuntu 18.04 中安装 Omnet++ 5.5.1 后，我使用了命令

./aloha

在 aloha 文件夹中可以看到显示模拟的 window。但是模拟一个小的 window 也会弹出，上面写着：

Unknown log format Character '<'

单击那个小 window 中的 'OK' 按钮后，所有模拟都消失了。我应该更改什么以及在哪个文件中享受运行它们？

运行命令

./aloha -u Cmdenv -c PureAloha1

给出以下输出

而命令

./aloha -u Qtenv -c PureAloha1

和前面提到的 window 的未知日志格式字符 '<'。请帮忙。

Answer 1

您的主目录的根目录中可能有一个旧的 .qtenvrc。尝试：

$ rm ~/.qtenvrc

.qtenvrc 包含 QTEnv 的各种全局初始化参数，包括提到的 logformat 参数。

Answer 2

如果您使用的是 windows，请转到：C:/users/user_name/ 然后删除名为：.qtenvrc

的文件

未知的日志格式字符“<”

Unknown Log format character '<'
