How can I install qt5 to Debian using commandline? - qt

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.

qmake not properly recognized in QT Creator under Debian 11 "bullseye"

I have installed QT Creator under Debian 11 "bullseye" (sudo apt-get -y install qtcreator), resulting in QT creator version 4.14.1.
Then I installed qmake (sudo apt install qt5-qmake), resulting in qmake version 5.15.2.
Now I want to add qmake in QT Creator options under Kits->QT versions, but it says
QT version is not properly installed, please run make install
and it refuses to work:
I have also another machine with Debian 12 bookworm, where I have been using this setup without any problem for several months (the yellow triangle in the screenshot below is only warning). On Debian 12 bookworm, the QT Creator is now version 8.0.1 (recently it was 6. something) and qmake version is 5.15.4:
Any idea how to make it work under Debian 11? I need to use the older environment, because I need specific older libraries to be build in the application.
I have tried almost everything that I found over the internet, but nothing helped. Usually the sources say to install qt5-default package, but this is not available in Debian 11.

Cant run qgis version Qt_5_PRIVATE_API not defined

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 need a minimal QT 5.0 Compiler install for Ubuntu 14.04 64bit

I need a minimal QT 5.0 Compiler install for Ubuntu 14.04 64bit
I just need to run qmake and have the QT includes, macros and libraries work under g++. I do not need The QT GUI development environment.
I tried the following...
wget http://download.qt.io/official_releases/qt/5.5/5.5.0/qt-opensource-linux-x64-5.5.0.run
... Follow instructions... At the end I get "Warning: QSqlDatabase: QMYSQL driver not loaded" which I need.
So I had to build from source, which takes overnight! (but does work)...
git clone git://code.qt.io/qt/qt5.git
cd qt5
git checkout 5.5
... Follow instructions... It does work.
I only want the compiler, not everything! How do I get that?
Alan.
Just install a package called build-essential + the Qt5 development packages you need (or qt5-default package). Ubuntu 14.04 has Qt 5.2.1 in the package repositories.
build-essential installs g++ tool chain and qt5-default installs the Qt5 development libraries.
Qt is not a compiler. It is a toolkit framework library coded for C++.
You need at least a C++11 compiler, like GCC (g++, at least 4.9) or Clang/LLVM (clang++)
You probably want to say that you don't need the QtCreator editor and IDE.

Glassfish updatetool linux 64 bit issue

I am trying to run glassfish updatetool my in Ubuntu 12.04 x64. When I run the program it gives me following error.
---------------------------------------------------------------
There was an error running
/home/mrmrumman/glassfish3/updatetool/bin/../../pkg/python2.4-minimal/bin/python
You are running on a 64 bit Linux distribution and the 32 bit Linux
compatibility libraries do not appear to be installed. In order to use
the Update Center tools you must install the 32 bit compatibility libraries.
On Ubuntu (and possibly other Debian based systems) please install the
ia32-libs package. On RedHat 4 (and other RPM based systems), you may
need to add multiple 'compat' runtime library packages. Please see the
Update Center Release Notes for more information
I already install this package still it doesn't work. What can I do?
You also need to install 32 bit version of libjpeg.so.62 .
You can do so by running this command
sudo apt-get install libjpeg62:i386
Source : https://java.net/projects/updatecenter/lists/dev/archive/2012-05/message/0
For glassfish4 on ubuntu 12.04 x64 make sure you have the recommended updates for precise ticked in Settings of Update Manager, then
sudo apt-get install ia32-libs
This is not quite enough though because the pkg command looks for those libs in the wrong directories for the ubuntu installation. Help it find them with this command
sudo ln -s /lib/i386-linux-gnu /usr/lib32
Then the pkg command should work fine.

in ubuntu 12.04 make cannot find Qt libraries

When I run make (after running qmake) I get the following error:
/usr/bin/ld: cannot find -lQtGui
/usr/bin/ld: cannot find -lQtCore
In synaptic it shows that I have installed libqtcore4 and libqtgui4.
There is no such directory as /usr/bin/ld.
Basically, I've installed the QtSDK, and QtCreator seems to work fine in that it can build the hello world program. But I want to be able to work from the CLI and run make. I suspect that I may need to redirect the make program to look elsewhere for QtGui and QtCore. If so, how do I find out where those libraries are? I'm running Ubuntu 12.04 and I've followed the advice of this page http://www.qtforum.org/article/28081/installing-qt-4-5-2-on-linux.html down to the last section where it talks about libraries. Any suggestions?
Install Qt using apt-get
sudo apt-get install libqt4-core libqt4-gui
or if you want everything
sudo apt-get install libqt4-*
The advice at http://www.qtforum.org/article/28081/installing-qt-4-5-2-on-linux.html is outdated and useless in your case since you have a recent version of Ubuntu. It leads to having two different versions of Qt side by side, which is technically possible but hard to manage.
You should install the qtcreator Ubuntu package and just delete the /opt/qtsdk... directory and undo the modifications suggested by the outdated instructions. It is essential that your PATH is not tweaked so that it's the Ubuntu version of qmake that is found when called from the command line.
If you still have compilation problems after that, they're likely to be solved by installing more packages, such as libqt4-dev or others Qt-related packages.
Also, /usr/bin/ld is not a directory, it's the linker program.
