Linking errors for trivial IntroJucer iOS application

MacOSX and iOS

Hi all,

Just diving into a "world of hurt" trying to port an application to iOS, so getting up to par on basic requirements I tried to create a GUI application via IntroJucer, but I get these linking errors :( :


Undefined symbols for architecture x86_64:

Building for the iPhone 6 simulator, and using JUCE of this revision: https://github.com/julianstorer/JUCE/commit/be9a2ff1bb6383c0e9f9419e1e3eb72434827d32

Help ?

By doing this in juce_ApplicationBase.cpp, I got it to link:

/* very easy way to support building Applier and lib on Darwin.iOS */

#if 1 //! JUCE_IOS
JUCEApplicationBase::JUCEApplicationBase()
    : appReturnValue (0),
      stillInitialising (true)
{
    jassert (isStandaloneApp() && appInstance == nullptr);
    appInstance = this;
}

But I feel it's not the right thing to do ?

Ok, my bad, this was added by our internal build system.... sorry about the noise!!
