Native Development

Hey,

Did you manage to solve this problem? I'm stuck at a similar point in my project.

Is there any solution for it ?

The solution would be lots of noisy developers to display interested in immediate C++ 11 support. Then Blackberry might decide to be nice and to enable proper support.  I am serious!

One of the lead platform developers wrote a month or so ago that currently qcc doesn't support C++11 or something like that. Go and vote/file a request for C++11 support.

It's possible to use some of it (lambdas, auto, raw strings), although I don't know how safe.  Seems okay for me.  Use at your own risk:

Under compiler options, add:  -std=c++0x

Under Preprocessor Options, use:  -U__GXX_EXPERIMENTAL_CXX0X__

This is so that any external headers you include don't use glib's special constructors for the stl.

I then made my own unique_ptr and move, forward.

I think the main problem with the c++0x and QNX is that QNX uses it's own STL (possibibly a modified Dinkum).

But don't try to use this with Qt...

I use some С++11 features (mostly lambdas) with Qt5 without any problems.

I don't know about Qt5 but as I've written above one of the developers commented that it is disabled for the NDK. You can find that in bugreports.qt-project.org if you are interested. Do you use Linux or Windows?

BTW What is the status of Qt 5 currently? Is it OK to start a graphics intensive project (with or without using C++11) and hope to finish/publish it in few months?

[trollixx]

I'm quite happy with Qt5 (though nothing in the bb world published yet). Its performance is much better than Qt4 (not Cascades). You need to bundle all libs, resulting bar is 9-10 MB.

And you are developing on Linux? (this is the link to the issue I've written above - the last post https://bugreports.qt-project.org/browse/QTBUG-28954)

[trollixx]

Yes, I am on Linux. And I have never tried using C++11 with Qt4.
