I got quite desperate on this, because I cannot install the open source Qt5 after I installed commercial Qt5 on my laptop.
This issue happened like this: My first trial of install Qt5, I chose the commercial license. Then when I tried to install PyQt5, it said my Qt5 license is commercial, not compatible with PyQt5 license. So naturally, as a open source lover, I uninstalled the Qt5. And reinstalled an open source version. But, no matter how many times I tried, PyQt5 says my Qt5 is still commercial license.
Dose anyone encounter the same issue here? And how did you solve it?
(I guess my last shot would be install a VM, but I sincerely hope I don't need to do that).
Updates: (July 28, 2015)
The issues turns out to be PyQt5 is not compatible with the newest Qt 5.5.0 at the moment. Choose a older version of Qt.
A couple of days ago,when I install PyQt5 in osx(10.9.5) the same problem came to me.I install qt-opensource-mac-x64-clang-5.5.0.dmg,and when I install PyQt-gpl-5.5.tar.gz,it said that Qt5 license is commercial, not compatible with PyQt5 license.So i just remove the Qt5.5 by "rm -rf Qt5.5",then i install qt-opensource-mac-x64-clang-5.4.1.dmg,at last everything works Ok.I googled but din't find something useful.maybe pyqt5 din't support the latest Qt5's license,but Qt5 has GPL and LGPL,pyqt5 has GPL,it should worked...ok,just gussing,hope this will helpful

I want to install Fluent Bit on macOS Catalina. All the resources available are for Ubuntu and Windows.
I followed this guide for Ubuntu [1].
Can anyone guide me on this?
[1] https://docs.fluentbit.io/manual/installation/linux/debian
I doubt that you can install those debian packages on macOS. But you can surely build from the source. There is a link on official documentation on how to build and install from source.
But from my experience you better get an understanding of possible errors that might come if you just try to download and install. Have a look at this post about pre-requisites. Once you have add those dependencies, surely you can build and installed on a macOS.
If you really want to install a package version on Mac, use it with homebrew.
You can install Fluent Bit on Mac with homebrew:
brew install fluent-bit
In my experience, on Mac it is very unstable and when I've attempted to do something simple like tailing logs you'll get lots of crashes.
I am installing OMNET++ 5.1.1. However, during the installation, it is reported that:
configure: error: Cannot build Qt apps, probably due to missing or too old Qt packages. Make sure Qt development packages are installed and newer than Qt 5.4. You can disable Qtenv by setting the WITH_QTENV variable to "no" in configure.user.
Then I download and install the Qt from https://www.qt.io/download/. But it still report the same problem. How can I solve this problem ? Thank you.
I assume you're running some kind of GNU/Linux, because on Windows and macOS, the bundled Qt libraries should just work.
Try installing the Qt5 development packages using your distro's native package manager, then they should be detected.
If you can't, or they are too old, take a look in the configure.user file, and adjust the value of the QT_PATH variable according to the instructions there.
EDIT:
Since the OS was clarified: On Windows, you don't need to download Qt, or any other library separately. They are all bundled with the OMNeT++ distribution, and should work fine.
Just make sure you always use the included mingwenv shell to install and run OMNeT++. In it, the environment variables are set up as necessary.
If you are installing OMNET++ on windows make sure you extract the zip file to a folder other than "Program Files" and deactivate your antivirus during the installation process.
I know that the développement of PySide for that version of Qt is stopped, but for some cases, I want to install it.
Where can I download the last developped version of PySide for Qt 5.x ?
What you need is PySide2.
This wiki page tracks the progress of PySide for Qt 5.x development and provides further information concerning the effort:
http://wiki.qt.io/PySide2?
If you want to install it on anaconda:
conda install pyside2
I am trying to install iPDC on a Centos unix laptop.
I am getting a make error when I attempt to install the programme - I have attached a screenshot of my problem.
The command run is sudo make install and I am attempting to install as the root user.
Your installed GTK version is probably too old to support this software. GtkBuilder (a component within GTK) showed up at version 2.12. To find out what version you have, run pkg-config --modversion gtk+-2.0 at the command line. But that version has been around for quite some time. What version Centos are you running? I assume 5, which is quite old.
Upgrading GTK can be tricky, as most of your desktop software relies on it. If you're in for an adventure, the "easiest" would be to upgrade your Centos OS (to 6.x). You might be able to compile a more recent GTK from source and keep it separate from your system GTK, but that will take some patience.
It seems that GTK is not installed.
Try something like: yum install gtk2 or yum install gtk2-devel
I'm just beginning to work with QT and qwt, I installed QT 5.1.1 and then installed QWT 6.1.0 using the instructions that was given :
qmake qwt.pro
mingw32-make
mingw32-make install
It installed without any errors. But I can't be sure if it's istalled correctly, how do I test it? I even have trouble using qwt! I searched in the widgets in QT designer and didn't find any thing related to qwt in there. I would appreciate it if you could guide me.
Thank you in adnvance
See http://qwt.sourceforge.net/qwtinstall.html.
Unfortunately it is not that easy to understand about designer plugins, but this is the fault of the designer - not the plugins.
