QPluginLoader cannot load plugin [solved]

GrahamL

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

@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
