Compiling for iOS failed - Memory ?

Lordful

Hello, I'm writing an iPhone app that uses QNetworkAccessManager && QSvgRenderer.

My code works like a charm on the desktop but on my iPad, I have this errors at compiling :

fatal error: too many errors emitted, stopping now [-ferror-limit=]

And many more.

Is this a problem of memory in my application ? Maybe there is too much dynamic allocation or something ?

Thanks for your answer.

Hi,

How big is your application ? Do you have assets in it ?

Lordful

@SGaist It's not a big application but there is some kind of these :

#ifdef TARGET_TYPE_XXX
#include <xxxx.h>
#else
...
...

Is it a problem on iOS ?

I also tried to add different type of c++11 to the pro file but anyway, that changes nothing.

CONFIG += c++11
QMAKE_CXXFLAGS += -std=c++11

It's strange

EDIT 1 : After working on an other project, It looks like it's not a problem with my project but with the environment. Even with a new project, I can't launch it on iOS, same errors.

What version of Qt are you using ? On what version of OS X ? Which Xcode are you using ?

Lordful

@SGaist Qt Version : 5.5 - OS X version : 10.11.5 - Xcode version : 7.3

Everything is up-to-date and it was working on monday and then errors. The project is still running on an other Mac..

That's strange, did you have any update in between from your system ?
