[Interest] How to include a Objective-C project as a .pri?

[Nuno Santos]

Hi,

I’m trying to add an Objective-C project as .pri

However, during compiling for iOS-clang, it complains about not knowing about NSObject and BOOL types. Isn’t this supposed to be part of the iOS-clang compilator knowledge? 

This is my .pri file. I have added TheAmazingAudioEngine as a git submodule:

ios {
    HEADERS += $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/TheAmazingAudioEngine.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioController+Audiobus.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioController+AudiobusStub.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioController.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioFileLoaderOperation.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioFilePlayer.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioFileWriter.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioUnitChannel.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioUnitFilter.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockAudioReceiver.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockChannel.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockFilter.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockScheduler.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEFloatConverter.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEUtilities.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/TheAmazingAudioEngine-Prefix.pch \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/Library/TPCircularBuffer/TPCircularBuffer.h \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/Library/TPCircularBuffer/TPCircularBuffer+AudioBufferList.h

    OBJECTIVE_SOURCES += $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioController+Audiobus.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioController.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioFileLoaderOperation.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioFilePlayer.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioFileWriter.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioUnitChannel.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEAudioUnitFilter.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockAudioReceiver.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockChannel.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockFilter.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEBlockScheduler.m \
                         $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEFloatConverter.m
                         

    SOURCES += $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/AEUtilities.c \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/Library/TPCircularBuffer/TPCircularBuffer.c \
               $$PWD/TheAmazingAudioEngine/TheAmazingAudioEngine/Library/TPCircularBuffer/TPCircularBuffer+AudioBufferList.c
}

The instructions for this lib relies in adding their xcode project to the xcode project but I usually use QtCreator to manage my projects and I only generate the xcode project for deploying. 

This is the kind of errors:

Any ideas?

Thanks in advance,
