This is a borderline question but it's a bit programmy so I thought I'd try here instead of Super User. I am trying to install templar, so I downloaded the source and attempted to run qmake to install it. When I do, I get this message:
Project ERROR: Unknown module(s) in Qt: xmlpatterns
I don't have particular interest in learning about the internals of Qt, other than what is needed to compile templar. Is this message telling me that the module can't be found, or that Qt doesn't know what to do with it?
And how do I remedy this error?
I had the same error while building an other project using Ubuntu.
This worked for me:
sudo apt-get install libqt5xmlpatterns5-dev
Your Qt distribution wasn't build with the xmlpatterns module. You need to download a new distribution from the website. In the worst case you will have to compile it yourself but it isn't quite hard.

Somewhat of a Ubuntu noob coming from windows, so i hope its an easy fix.
This is the error I get when I try to launch Anaconda:
Cannot mix incompatible Qt library (version 0x50905) with this library (version 0x50907)
Aborted (core dumped)
So my thought is that there is an environment variable that needs to be tweaked to point to a native version of qt that comes with conda. Any help would be great, i need line by line instructions if possible, still new.
Thanks
I was running a retro theme on my terminal that somehow interfered with the QT versions.
I've been using OpenCV and Marble libraries compiled and linked with Qt. Every time I do it I have problems running cmake to make these libraries. it seems paths in the qt cmake files to other qt cmake files are incorrect. I get errors like:
CMake Error at CMakeLists.txt:67 (find_package):
By not providing "FindQt5DBus.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5DBus", but
CMake did not find one.
Could not find a package configuration file provided by "Qt5DBus" with any
of the following names:
Qt5DBusConfig.cmake
qt5dbus-config.cmake
Add the installation prefix of "Qt5DBus" to CMAKE_PREFIX_PATH or set
"Qt5DBus_DIR" to a directory containing one of the above files. If
"Qt5DBus" provides a separate development package or SDK, be sure it has
been installed.
I can fix this in Ubuntu by running
sudo apt-get install qt5-default
This is fine in Ubuntu, but now I am trying to compile these libraries on mac and windows now. Anyone know a way to get a Qt with all of these paths already correct? tried the installer on windows and mac, and brew on mac. I don't really have time to play with fixing each one of these errors one by one
At least Qt 5.5 on Windows (using the Qt installer) should work out of the box. It has DBus included. Which Qt version are you using currently?
I want to compile PhantomJS with gstreamer. I downloaded the source code and started the build process with
./build.sh --qmake-args WEBKIT_CONFIG+='use_gstreamer'
I get the following Error
Project ERROR: gstreamer-1.0 development package not found
I have an debian 8.0 system with installed libgstreamer1.0 and glib2.0 (installed with apt-get).
Can someone help me?
If you haven't installed them, you'll need the development packages as well which should be something like libgstreamer(X.X.X)-dev, where X.X.X is whichever version of gstreamer you have installed. The development package has the necessary header files required for compilation.
you may need to modify the build script to add "{GStreamerInstallDir}/1.0/{architecture}/lib/pkgconfig" to the CMAKE_MODULE_PATH configuration so cmake can find the package.
Not sure how to do this in your environment as I build on a windows OS where I just specify this using an environment variable from a wrapping batch script.
I am trying to get qt webengine running on my laptop for the first time, but can't seem to build it. I am following the instructions from here:
https://wiki.qt.io/QtWebEngineHowToTry
On the last few steps, I had to run "qmake -r" on the qtwebengine directory. This is the output:
SSL............................... Using system NSS
ICU............................... Using internal copy (Default, force system ICU with WEBENGINE_CONFIG += use_system_icu)
FFMPEG............................ Using internal copy (Default, force system FFMPEG with WEBENGINE_CONFIG += use_system_ffmpeg)
Proprietary codecs (H264, MP3).... Not enabled (Default, enable with WEBENGINE_CONFIG += use_proprietary_codecs)

Project ERROR: Unknown module(s) in QT: webchannel
This error happened right after I installed WebKitGtk+ from here (http://trac.webkit.org/wiki/BuildingGtk) and ran "Tools/gtk/install-dependencies" and "Tools/Scripts/update-webkitgtk-libs". Before I installed WebKitGtk+, qmake would terminate at a later point.
(I installed WebKitGtk+ because, previously, running "qmake -r" on the qtwebengine directly resulted in an "unmet dependency: harfbuzz" error that I tried to fix on my own via google, and the WebKitGtk+ page was the only lead I could find that would supposedly fix that issue... big mistake!).
I am running on a (mostly freshly reformatted) Ubuntu 15.04 laptop. I installed qt5 via apt-get install, but apparently I have both qt4 and qt5 plugins installed, as well as qtchooser (I'm guessing from the WebKitGtk+ installation scripts).
Here is the output of "qmake --version":
QMake version 3.0
Using Qt version 5.4.1 in /usr/lib/x86_64-linux-gnu
Any help would be greatly appreciated, as I'm excited to try out qt webengine!
In case anyone else has the same problem, I fixed it by installing qt 5.5.0 from here http://download.qt.io/official_releases/qt/, and using the associated qmake binary from that installation. I guess installing qt from 'sudo apt-get install' still has some issues that won't work with qtwebengine.
I'm trying to run a simple client example using QTWebsockets using Qt Creator, already add the
QT += websockets
But it throws this when i run build or qmake
:-1: error: Unknown module(s) in QT: websockets
I tried
QT += core websockets
Then realized that since installed Qt Creator from the repositories it wasn't up to date, so I reinstalled it from the Qt website but the problem persisted, I then ran pkg-config --modversion QtCore and it returns 4.8.6, thing is, in the QT version tab of qt creator it shows 5.4.1 to GCC compiler which is the compiler I’m using, in /opt/Qt/5.4/gcc_64/lib there is the QT5WebSockets module even in the help tab are listed the QT5 modules but I can't use them.
Tried with SerialPort and it didn't work, tried with Opengl and it worked which means is a version problem but I can't seem to find how to solve.
sudo apt-get install libqt5websockets5-dev
I solved it, the problem was that I just opened the project I made with qt4, when I tried to build it in the freshly installed qt creator the .pro.user file kept pointing to all qt4.
Solution, create a new project and add the source from the first, or change all the references from qt4 to qt5.
sudo zypper install libqt5-qtwebsockets-devel
