Installation and Deployment

I'd go with writing a small helper program that returns what is currently available on the system and then act based on it.

It's been added to Qt 5.5.0

@paolomanili said: lintian overrides (1) In fact I see many programs placed in /opt in Ubuntu. One consideration .. some installers of Ubuntu place / and /home in separate partition for ease of reinstallation. (2) Although I've installed Debreate I haven't yet progressed to using it for packaging. But this article addresses the points you raise. http://forum.pinguyos.com/Thread-How-to-create-a-deb-from-an-already-compiled-program I'll be interested to see if you get your Qt > deb workflow to a Ubuntu PPA release.

Hi, If you want to developer without your HDD then you should install the Qt you built on your Pi.

Actually ,I installed the downloadable version for mac from the website.

In case other people are struggling with the same problem, i left here the template for using latest version of Qt with Travis: sudo: required dist: trusty before_install: - sudo add-apt-repository --yes ppa:beineri/opt-qt551-trusty - sudo apt-get update -qq install: - sudo apt-get -y install qt55[QTPACKAGE] script: - source /opt/qt55/bin/qt55-env.sh - /opt/qt55/bin/qmake - make In case Travis upgrade their build system, just change the dist: trusty to whatever distro they upgrade to.

Just add -no-c++11 option to the ./configure file. Ok, i made what @granolamatt suggested and it worked.

@Zingam said: Do you have any idea what is preventing the online installer to get the meta information? It just randomly stops from 40% to 99%. And this happens for a few days now. This might explain it: https://forum.qt.io/topic/35768/public-service-announcement-2013-12-21-qt-download-mirror-system-is-partially-broken You can use Resource Monitor to see where your computer is trying to download the files from. Are both of your computers using the same download server?

I figured it out. I had to copy the file C:\Python34\Lib\site-packages\PyQt5\qml\QtQuick.2\qmldir to C:\Python34\Lib\site-packages\PyQt5\examples\quick\models\stringlistmod el\dist\stringlistmodel\qml\QtQuick.2. I think pyinstaller should've copied that file as well, but it didn't.

Was probably an issue on the server side

Ah....haha, online installation solved problem...

Completing the story. Eventually I got myself out of this hole by ... (a) adding a qt.conf file to same location as scribus-ng and scribus-trunk binaries (/usr/bin) [Paths] Prefix= ../../opt/qt55 Translations=i18n Libraries=lib Plugins=plugins (b) adding Qt paths to ~/.profile export PATH="/opt/qt55/bin":$PATH export LD_LIBRARY_PATH="/opt/qt55/lib":${LD_LIBRARY_PATH} (c) reboot Thanks for advice.

@SGaist Thank you, mister ) It works!

@crystax Hello, here I am again with a similar issue. I'm trying to build Qt (5.6.0-RC) using the last version of your Crystax NDK (10.3.1). My configure command line looks like this: ./qt-everywhere-opensource-src-5.6.0-rc/configure -xplatform android-g++ -nomake tests -nomake examples -android-ndk /Users/ro/lib/ANDROID/crystax-ndk-10.3.1/ -android-sdk /Users/ro/lib/ANDROID/android-sdk-macosx/ -android-ndk-host darwin-x86_64 -android-toolchain-version 4.9 -skip qttranslations -skip qtserialport -no-warnings-are-errors -prefix /Users/ro/lib/QT/Qt5.6.0-rc-android-crystax -android-ndk-platform android-19 -v meaning that I'm using the crystax NDK 10.3.1, my Mac as the host compiling Qt, the 4.9 NDK toolchain version, and the android-19 NDK platform version. Well, after changing QTDIR/qtbase/mkspecs/android-g++/qmake.conf by modifying these lines (Line 83): ANDROID_SOURCES_CXX_STL_LIBDIR = $$NDK_ROOT/sources/cxx-stl/gnu-libstdc++/$$NDK_TOOLCHAIN_VERSION/libs/$$ANDROID_TARGET_ARCH $$NDK_ROOT/sources/crystax/libs/armeabi-v7a ANDROID_SOURCES_CXX_STL_INCDIR = $$NDK_ROOT/sources/cxx-stl/gnu-libstdc++/$$NDK_TOOLCHAIN_VERSION/include $$ANDROID_SOURCES_CXX_STL_LIBDIR/include $$NDK_ROOT/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/include the configure script doesn't complain, and running make, it starts compiling. But I'm getting a compile error: qthread_unix.cpp:559:49: error: 'PTHREAD_INHERIT_SCHED' was not declared in this scope pthread_attr_setinheritsched(&attr, PTHREAD_INHERIT_SCHED); Having a look at the source file, that piece of code should only be compiling if QT_HAS_THREAD_PRIORITY_SCHEDULING is defined, which isn't true for ANDROID. That makes me think that probably the Crystax NDK (or toolchain, sorry, I'm a bit lost here) is not #defining ANDROID. A similar problem as described in this bug report: https://bugreports.qt.io/browse/QTBUG-41382. (So the compilation process doesn't know we are building for Android?) Also it's worth mentioning that replacing the Crystax NDK by the current Google provided "android-ndk-r10e", the compilation is successful. Any idea on how could I successfully compile Qt for Android using the Crystax SDK? Thanks, Robert.

Thank u so much @chris for your support. i got my Qt compiling my code

A bit outdated, are you locked to that old version ? What about my other questions ?

Other way was to create plugin directory, and insert platform directory inside plugin folder. This makes my app works well on any windows system :-)

Thanks everyone for your help. In summary, I download and install: Qt 4.8.6 (http://download.qt.io/archive/qt/4.8/4.8.6/qt-opensource-windows-x86-mingw482-4.8.6-1.exe) QtCreator 2.5.2 (https://download.qt.io/archive/qtcreator/2.5) MinGW 4.8.2 (from https://wiki.qt.io/MinGW, I select the appropriate link to Qt 4.8.6) Now I can build my application. Problem solved.
