Did I find a Bug? [Project wont compile anymore]

[xtlc]

I was working on my project all day long and tried to add the QCustomPlot .cpp and .h files, which didn't work as I wished. I removed them, and since that time I can't compile any more:

I tried to google:

moc: Too many input files specified

and

[release\moc_qextserialport.cpp] Error 1

with barely success. What did I do wrong? I read in the forums this can happen if I included the QExtSerialPorts wrong, but I didn't change anything 18:08:36: Der

Prozess "C:\Qt5.1.0\Tools\QtCreator\bin\jom.exe" wurde mit dem Rückgabewert 2 beendet.

Ok... really weired. It works some time to compile. Why is that?

Here is the information you have given us... you have a project that did not include QCustomPlot (whatever that is), you added QCustomPlot, removed QCustomPlot, and the project still does not include QCustomPlot. The project no longer compiles with errors related to moc and you think it has something to do with QExtSerialport.

Have you re-run qmake since you modified your PRO file?
