LeaA

the problem solved

Hi
What was the problem and how did you solve it?

LeaA

the problem was that the plugin wasn't created good and the QPluginLoader wasn't recognized it as a plugin.

i returned the macro Q_OBJECT to InPluginImp class and i moved the inheritance from QOBJECT to the InPluginInterface class.

GrahamL

Ah
Please mark the topic as SOLVED
Thanks

hi,
now i getting this error:
C:\workspace\16-5-15\src\mainProject\build-mainProject-Desktop_Qt_5_3_MinGW_32bit-Debug\VisualReceiverErrorsAnalysis\debug\moc_inpluginimp.cpp:149: error: undefined reference to `InPluginImp::InPluginImp()'

and this one:
moc_inpluginimp.cpp:-1: error: undefined reference to `InPluginImp::getProcessing(myPlotInterface&, QVector<ReducingInterface*>)'

collect2.exe:-1: error: error: ld returned 1 exit status

there is a solution for it?..

SGaist

Did you properly implement both these functions ? Do you build the corresponding cpp file ?

LeaA

@SGaist

yes..

LeaA

@SGaist

it seems like a problem with the moc.cpp file of inpluginimp

LeaA

when i putting down the Q_OBJECT macro from the inPluginImp class the errors gone but the again the first problem in this topic comming back

SGaist

When adding/removing the Q_OBJECT macro, do you re-run qmake before building ?

LeaA

@SGaist

yes

LeaA

@SGaist

it says to me that the moc_inpluginimp.cpp file isn't found..
but the file is in the build directory of the project in the debuge directory

#ifndef INPLUGININTERFACE_H

@jalomic

sorry,i didn't understand you..

@jalomic said:

#pragma once

#ifndef INPLUGININTERFACE_H and #pragma once - it is the same thinks.
You not need #ifndef INPLUGININTERFACE_H if you have #pragma once
Sorry for offtop

jalomic

@LeaA Try to disable "shadow build"

@jalomic

I put down some header files from the pro. file and it solved
