Compiling Qt lib for iOS - 5.2.0
-
Hello all !
I'm working on "QCA":http://quickgit.kde.org/?p=qca.git (Qt Cryptographic Architecture) and we're working on updating it for Qt5 while keeping Qt4 compatibility. I'm trying to compile an app which uses QCA lib for iOS using Qt 5.2.0 (compiled from sources).
QCA uses cmake, I'm experiencing some issues when compiling with cmake, here are my command lines
@$ QTDIR=~/Qt5.2.0/5.2.0/ios PATH=~/Qt5.2.0/5.2.0/ios/bin:$PATH cmake -D CMAKE_BUILD_TYPE=Debug . // No problem
[...]

...@Here is the "./configure" command line for Qt 5.2.0, which I've make'd today without issue:
@./configure -prefix /Users/Max13/Qt5.2.0/5.2.0-iOS -debug-and-release -opensource -confirm-license -nomake examples -silent -xplatform macx-ios-clang@Do you guys have an idea on why this issue and how to fix it please? Thanks.

Hi,
Are you sure the paths are correct ? It looks like the prefix of your configure line doesn't match with what you give to cmake

What does
@lipo -info libQt5Core_debug.a@
return ?

@MacBook-Pro-de-Adnan:build Max13$ lipo -info /Users/Max13/Qt5.2.0/5.2.0/ios/lib/libQt5Core_debug.a
input file /Users/Max13/Qt5.2.0/5.2.0/ios/lib/libQt5Core_debug.a is not a fat file
Non-fat file: /Users/Max13/Qt5.2.0/5.2.0/ios/lib/libQt5Core_debug.a is architecture: armv7@I think I'm getting it. I was building for iPhone-Simulator, I think it's trying to link with the wrong library (as I've noticed that I have some *_iphonesimulator.a"

Looks like it indeed. Both don't use the same architecture. To avoid this, you could try to do a simulator only build so you'll ensure that you only have one set of libraries to link to (at least to start your tests)
