Building 5.2 (stable) with libc++ for c++11 support?

kersson

So was the solution to recompile Qt for iOS with c++11 using the method that rosetter described (modifying the qtbase/mkspecs/macx-ios-clang/qmake.conf file)?

yes, that's what works for me.

Hi rosetter,

I have changed the qmake.conf in the way you described. But after a configure the line which shows the C++11 support says no.

"see":http://qt-project.org/forums/viewthread/38373/#162619

Will it work yet?

kortus, even though the line says C++11...no, it is actually enabled. I confirmed that after making the change to the mkspec and compiling Qt for iOS, I was able to compile and deploy projects with CONFIG += c++11 for both simulator and device.

However, I'm still working on a solving a "semi-related issue.":http://qt-project.org/forums/viewthread/38541/

Let me know if you have any thoughts :)

kortus

kersson, you are right, it works.

Hi rosetter,

Could you please provide us the steps for doing the Qt compilation?

Thanks

Hi SGaist,

Is there any information about the compilation steps of the Qt provided at http://qt-project.org/downloads?

Thanks

SGaist

Hi,

Do you mean the exact parameter they use ?

Personally I used the line provided "here":http://qt-project.org/doc/qt-5/building-from-source-ios.html

SGaist, thanks for replying.

Yes, I meant that (Sorry for my english).
What if I want to build all the Qt "products" included in the download page?
I want to build them in the same way (exact the same) as Qt does.

My question is: what are the parameters (to the configure script) used by Qt for the products provided in the download page?
Is there any information about this?

I have another doubt:

I checked the file:
5.3/ios/mkspecs/macx-ios-clang/qmake.conf

that includes:
5.3/ios/mkspecs/common/clang-mac.conf

In the last file, the following is specified:
QMAKE_CXXFLAGS_CXX11 += -stdlib=libc++
QMAKE_LFLAGS_CXX11 += -stdlib=libc++

(This is the same for Qt5.2)

According to what I understand, Qt 5.2 and 5.3 (ios) are compiled to use LibC++.
I do not understand why it is not.

Thanks!
Fernando.

You have that "wiki entry":http://qt-project.org/wiki/Building-Qt-Package that explains how.

I don't understand your last question. Since 5.2, they do use libc++
