运行ometpp.ini文件时遭遇OMNeT++解析错误的解决方案求助

This error happens because OMNeT++'s display string syntax doesn't allow spaces between the tag name (like i here) and the equals sign. Let me walk you through the fix:

What's triggering the error? #

Looking at your NED code, the line @display("i = block/routing"); has unnecessary spaces around the equals sign. OMNeT++'s parser treats that space right after i as part of the tag name—since spaces aren't allowed in tag names, it throws the "illegal character" error you're seeing.

How to resolve it #

Just remove the spaces around the equals sign in the display string. The strict syntax requires the tag name and its value to be connected directly with = without any whitespace in between.

Here's your corrected code snippet:

simple nodeR {
    parameters:
        @display("i=block/routing");
        @signal[arrival](type="long");
        @statistic[hopCount](title="hop count"; source="arrival"; record=vector,stats; interpolationmode=none);
    gates:
        inout gate[];
}

Quick tip for future work #

All display string properties (like x, y, label, etc.) follow this rule. Never add spaces between the property name and the = sign, otherwise you'll hit the same parsing issue again.
