Follow the installation guide from the readme file in qgroundcontrol, I still have problem of missing package in QT. I have downloaded QT installer (https://www.qt.io/download-open-source/) and installed it to "home/user/QT".
It this problem because...
I installed to the wrong location which is not default location of QT then QT cannot find new installed-packages. Where is the default location to install?
or I have to do some more configuration?
OS : Ubuntu 16.04

I am running Ubuntu 18.04 and I cant seem to get qgis to run anymore. The error I get is:
/usr/bin/qgis.bin: relocation error: /usr/lib/x86_64-linux-gnu/libQt5QuickWidgets.so.5: symbol _ZN15QQmlMemoryScope5stateE version Qt_5_PRIVATE_API not defined in file libQt5Qml.so.5 with link time reference
my qmake version is:
QMake version 3.1
Using Qt version 5.9.5 in /usr/lib/x86_64-linux-gnu
I have tried to link to qt5 but that did not change anything.
sudo ln -snf ../../../../share/qtchooser/qt5-x86_64-linux-gnu.conf default.conf
You need to uninstall QGIS and reinstall with the latest stable release. Using sudo apt-get install qgis* python3-qgis* to install is not precisely the best method because of the wildcard. The official instructions suggest using: sudo apt install qgis qgis-plugin-grass.
The instructions for best installation procedure on Ubuntu for LTS releases is posted here.
I installed QT creator in debian linux. If I try to create a new project, in Kit option I got the error like "No valid Kit found". If I go to Tools ->Options -> Build&Run -> kit, there is no options to select. But I installed same in ubuntu, it is working fine without same problem. What im missing?
Also suggest me if I need to reinstall the QT creator or something else...
Its time to explain the tricks to install QT creator in debian linux operating system.
STEP 1: dont install just QT creator in your PC.
Install whole package of QT [link to download QT SDK below][1]
[1]: http://www.qt.io/download-open-source/#section-2 , so that you will get all the libraries and dependencies.
After downloading the file is in the ".run" format . Install the downloaded file in your terminal (by giving commands).
STEP 2: install
sudo apt-get install g++
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
in your terminal.
STEP 3: install
sudo apt-get install libcanberra-gtk-module
sudo apt-get install libcanberra-gtk-module:i386
now restart your system once and create new project.It should work
I like to thank agold for his guidance , Actually he spent more than 3 hours to resolve this issue. :)
I need to install Qt5 to my Debian using commandline. How can I do that?
My system:
debian 2.6.30-vortex86mx-yh
I am trying to install using qt online installer from qt-project.org.
But after ./qt.run I get this error:
libstdc++.so.6 version glibcxx_3.4.11 not found
I try to install libstdc++6. but Debian said it is already newest version.
cat /etc/issue result is:
Debian 5.0
Also my debian has no gui. I have to do it using commandline.
Try this command for installing from default debian 5 repository:
#apt install g++
#apt install qtcreator
#apt install qtdeclarative5-dev
You should be able to run the qt-installer in a decent debian version. Get Version by:
cat /etc/issue
On older versions or "unsupported" versions you can still download the sources and build the libraries yourself, which is probably your way to go, since the vortex86-builds are pretty limited in compiler flags. Compiling is rather easy, depending on your needs. The configure script itself gives you a lot of hints regarding possible flags.
Another alternative is to find a user-managed repository that has QT5 for your debian version and add this repository to your sources.lst, so you could perform a apt-get install libqt5.
I installed Qt 4.8 from developer.nokia website which is a .run file. Because it's from nokia i assume the libraries are compiled with openssl...
I use ubuntu 11.10 and it has openssl already installed.
I can't make the QSsl classes working because of this, what am i doing wrong?
Anyone know a proper Qt SDK 4.8 that works fine?
Thanks!
export QTDIR=/home/user/qtsdk-2010.05/
export PATH=$QTDIR/bin:$QTDIR/qt/bin:$PATH
export LD_LIBRARY_PATH=/home/user/qtsdk-2010.05/lib/:/home/user/qtsdk-2010.05/qt/lib/:$LD_LIBRARY_PATH
please change qtsdk-2010.05 to your sdk path
and make sure the binary path and lib is correct, then qmake ,make clean , make
Solved the problem installing qt-sdk from the repositories.
sudo apt-get install qt-sdk
A newer version of the Qt Creator can be found on qt-project.org
However for Ubuntu 11.10 Qt 4.7 will be installed and not 4.7. Qt 4.8 is available on the newer Ubuntu versions' repositories.
I downloaded QtSDK from website and installed on my computer, my OS is Ubuntu 10.04.
When I compile a project of OpenGL, there is an error "GL/gl.h no such file or directory".
but when I compile the projet under windows, it works. Why?
Who can resolve this problem for me?
You need to install the OpenGL development files. In Ubuntu they're in the package libgl1-mesa-dev. You'll also want to install libglu1-mesa-dev.
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
I recommend installing GLEW alongside, since you'll jump the extension hoops to get OpenGL-3 functionality.
Edit
Here's how to get GLEW in Ubuntu (from the comments):
sudo apt-get install libglew-dev
