IOS/iPad fstream pointer error

carlinski

@std::fstream* ptr_fsZoomfile = new std::fstream(ss.str(), std::fstream::in | std::fstream::binary);@

This line works great on Linux, Mac, Windows and Android. On iOS (iPad) it crashes. File is all OK because if I create it as a none pointer it works OK.

I need to create it as a pointer because it is going into a vector.

Any thoughts?

What is ss? What does ss.str() return?

carlinski

ss is a stringstream I use to build the filename.

str returns const string.

I have also checked that by putting a const string in, i.e. the full typed path.

Hi,

This question is not directly related to Qt, you should rather ask it on an iOS developer forum.

carlinski

Yes, should have posted on an iOS site really.

Anyway, for anybody searching:

I managed to sort this today, by using a QSharedPointer, which xcode is much happier with:

@QSharedPointer<fstream> ptr_fsZoomfileMultiple = QSharedPointer<fstream> (new fstream(ss.str(), std::fstream::in | ios::binary));@
