Building qt5.1 for iOS

oxygen77

I've followed the instructions from http://qt-project.org/doc/qt-5.1/qtdoc/ios-support.html, everything went fine, no error.

the sdk I choose is iphonesimulator6.1

I've build qtscript and qtquick1

Then I tried de build the example qt-ios-demo.xcodeproj during qmake I get a warning saying that .qmake.cache was not present, and when I tried to open the generated Xcode project I get the following error:
Project /Users/tof/qt5/qt-ios-demo/qt-ios-demo.xcodeproj cannot be opened: The project contains no build configurations - it may have been damaged

any idea ?

still no chance with this, I tryed several other things like doing a checkout on ios branch as explained in some old howto I saw

is there a way to check for which sdk qt was build, I suspect that this is the part that is not working

radzenko

have this same problem, any idea ???

i tried to build the sdk with several options but every time get this same error:

(...) .qmake.cache was not present (...) qt-ios-demo.xcodeproj cannot be opened: The project contains no build configurations – it may have been damaged.

really, no one can explain it?

Please post how You build your solution for iOS.

I am getting this exact same issue as well, trying random things to figure out the solution, no luck yet.

Details:

First try:

```
  Did ./configure not /configure
```

  Configure step included  -sdk iphone simulator

```
  Chose open source license
```

  qtbase-ios and qt-ios-demo are siblings in the same directory

Second attempt generated a qt-ios-demo.xcodeproj that did not give an error on loading, but wouldn't build.

Details:

Deleted (rm -rf) both qtbase-ios and qt-ios-demo and got fresh copies via git.
Did not include the -sdk iphonesimulator in the configure step.
Chose commerical license
107 issues, 9 linker warnings, 98 linker errors

P.S. Following these steps, btw: http://blog.qt.digia.com/blog/2013/03/05/qt-for-ios-preview/ (Qt for iOS Preview)

I have no clean solution yet.
Temporary I use the SDK from site http://mediator-software.com and build my project as static library. Then I linked it in the pre-configured xcode project.
It works, but you get nasty overlay with some text like "iOS Plugin Mediator Software...".

Third attempt does not give any errors but silently refuses to generate an xcodeproj file when I run qmake.

Details:

Deleted (rm -rf) both qtbase-ios and qt-ios-demo and got fresh copies via git.
Did not include the -sdk iphonesimulator in the configure step
Chose Open Source license
Did make -
For qt-io-demo, ran ../qtbase-ios/bin/qmake, but no qt-ios-demo.xcodeproj is created.

The file /Users/kenn/Documents/DEV/qt-ios-demo/qt-ios-demo.xcodeproj does not exist.

Then I tried to install QT, even though the 5.1 preview instructions did not specify to do so, in case it was needed. I followed the instructions here: http://qt-project.org/doc/qt-5.1/qtdoc/install-mac.html

And install failed with missing symbols in the linker:

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[3]: *** [../../../bin/moc] Error 1

make[2]: *** [sub-moc-install_subtargets] Error 2

make[1]: *** [sub-tools-install_subtargets] Error 2

make: *** [sub-src-install_subtargets] Error 2

finally get it working, in fact doing nothing special, just clean fresh sources and the tutorial from qtdoc5.1, I guess a commit was made in the source to correct something

Steps I followed:

git clone
perl init-repository --no-webkit
in qtbase: ./configure -xplatform unsupported/macx-ios-clang -developer-build -release -sdk iphonsimulator6.1
and then still in qtbase: make
-in qtscript and in qtquick1: ../qtbase/bin/qmake; make

And then I could try the example from : git://github.com/msorvig/qt-ios-demo.git

in the qt-ios-demo folder I I just called : ../qtbase/bin/qmake and then open the generated xcodeproj file using open
