I have 2 versions of Qt for different arm devices and different toolchains: Qt 4.5.2 and Qt 4.7.3. Both versions are supposed to be placed in /opt/onyx/arm directory :(
The following error is occurred if I move the 1st Qt build in another directory (/usr/arm-marvell-linux-gnueabi) and run qmake:
#!/bin/sh
export QTDIR=/usr/arm-marvell-linux-gnueabi
/usr/arm-marvell-linux-gnueabi/bin/qmake -o Makefile.qt.onyx.a6x -spec qws/arm-marvell-linux-gnueabi-g++ project.pro
./run_qmake1.sh
Could not find mkspecs for your QMAKESPEC(qws/arm-marvell-linux-gnueabi-g++) after trying:
/opt/onyx/arm/mkspecs
Error processing project file: project.pro
What could be the issue and how can I resolve the /opt/onyx/arm conflict?
I would recommend grepping through /usr/arm-marvell-linux-gnueabi for any references to /opt/onyx. If you can't successfully change them (because they're in a binary), you could use symlinks to switch toolchains as needed.

I'm trying to build a project with MSVC 2013 and Qt Creator 4.4.0 with JOM and was having issues to configure JOM. So, I tried to erase Qt Creator's configuration files completely and start from scratch.
In the fresh Qt configuration, after I opened the project, I set the CMake (3.9.3) location and ran CMake on the project. Unfortunately, by default, the Qt 5.6.3 Kit seems to choose the NMake generator instead of the NMake JOM generator. After deleting the build directory, I changed the generator to NMake JOM in the Kit configurations, but met the following error message:
CMake Error: Generator: execution of make failed. Make command was: "jom" "/NOLOGO" "cmTC_276f9\fast"
Any idea of why this is happening? As far as I remember, Qt Creator is supposed to build the projects with JOM by default.
I had the same exact problem. Add the location of jom.exe (typically it is path like [...]\Qt5.12.1\Tools\QtCreator\bin\) to your PATH.
I have application which uses QFtp class.I have made in Qt 4 version.
But now i want to complie QFtp classe in Qt5 but it's showing some error like:
'QFtp' doesn't name and type.
how to resolve this issue. I don't want to use QNetworkAccessManager. is there any way to this?
Thank you
For the sake of completeness, the steps to use the add-ons are:
Download the sources for the add-on from https://github.com/qt/qtftp
Extract the sources somewhere (e.g. Qt5.x.y/Src/qtmyaddon)
Open a console in that folder
Read readme.txt and run the appropriate commands with the latest QT version
Run qmake
Run make (or nmake or mingw32-make or whatever)
Run sudo make install (nmake install, mingw32-make install, ...)
In the .pro file of your project, add "QT += myaddon" (e.g. "QT += ftp")
Run qmake on your project
Compile your project
I followed these instructions in the configuration of OpenCV SDK for using it in Qt Creator IDE, but I couldn't conclude point 6.5, due to configuration errors in Cmake-GUI. I setup the configuration in CMake of the compilers gcc and g++ contained in Qt folder for MinGW32, and all looks Ok. But when Cmake-GUI starts the process of build configuration it ends up saying
"Error in configuration process, project files may be invalid".
It can't find the following:
QT_QMAKE_EXECUTABLE;
Qt5Concurrent_DIR;
QT5Core_DIR;
QT5Gui_DIR;
QT5Test_DIR;
QT5Widgets_DIR.
After this issue I tried to go on with following points of configuration tutorial, without reaching the final instruction of mingw32-make install. I'm using the following versions of softwares: Qt 5.3.0, OpenCV 2.4.9, CMake 2.8.12.2. My OS is Windows 7.
How can I recover the missing Qt files in CMake configuration?
Is there an alternative way for configuring OpenCV with Qt (like using precompiled build of OpenCV libraries)?
You just need to indicate CMake the correct paths to each one. Click oh the path to browse and set each one individually:
QT_QMAKE_EXECUTABLE;
For this one, you need to search inside the Qt installation folder for the /bin directory. On it, you' ll find the qmake.exe. In my case it was C:/Qt/5.3/winrt_x64/bin/qmake.exe
All the following ones are in the Qt's /lib/cmake directory. In my case: C:/Qt/5.3/winrt_x64/lib/cmake :
Qt5Concurrent_DIR;
C:/Qt/5.3/winrt_x64/lib/cmake/Qt5Concurrent
QT5Core_DIR;
C:/Qt/5.3/winrt_x64/lib/cmake/Qt5Core
QT5Gui_DIR;
C:/Qt/5.3/winrt_x64/lib/cmake/Qt5Gui
QT5Test_DIR;
C:/Qt/5.3/winrt_x64/lib/cmake/Qt5Test
QT5Widgets_DIR.
C:/Qt/5.3/winrt_x64/lib/cmake/Qt5Widgets
Then click generate. It' ll show a new error and ask you for the QT5OpenGL_DIR. Just as before, show CMake the correct directory. In my case: C:/Qt/5.3/winrt_x64/lib/cmake/Qt5OpenGL. Finally, click Configure again, and then Generate, and now you're done creating the build files.
You have to specify the location of Qt manually by passing it as an argument for QT5Core_DIR. Qt5_DIR or CMAKE_PREFIX_PATH does also the trick.
Example
Given your Qt 5 is installed at /opt/selfcompiled/Qt5. When calling cmake, add the flag from above:
cmake -DQt5_DIR=/opt/selfcompiled/Qt5 <pathToSourceDir>
Once the Qt 5 directory is set and found by CMake, all the other variables related to Qt 5 should be found from there, too.
I built a static version of Qt 5.1.1 msvc. but after building there is no qmake.exe and when I execute "qmake" it's not recognized as a internal or external command.
what is the problem?
There's no way the build would succeed without qmake being built and executed numerous times. It's there. Look in your build's bin directory. It won't magically be added to your PATH!
I have just purchased a Macbook (yes I am a complete noob on Mac though I have some considerable experience with Linux) and I'm trying to build my Qt application on it. I have installed XCode and the Qt SDK but when I try to build my project on Qt Creator all I get is the following error during qmake:
Running build steps for project TimeTracker...
Starting: "/usr/bin/qmake" /Users/raphaelcruzeiro/Documents/Projects/Timely/Widget/TimeTracker/TimeTracker.pro -r -spec macx-g++
Failure to open file: /Developer/Applications/Qt/Makefile
Unable to generate makefile for: /Users/raphaelcruzeiro/Documents/Projects/Timely/Widget/TimeTracker/TimeTracker.pro
The process "/usr/bin/qmake" exited with code %2.
Error while building project TimeTracker (target: Desktop)
When executing build step 'qmake'
Any ideas on what is going on? /Developer/Applications/Qt/Makefile indeed does not exist.
EDIT:
Ok, I know what is going on but I don't know how to fix it. When I ran qmake from the terminal everything went just fine. I believe that Qt Creator is trying to build my application on the Qt directory itself and it does nt have permission for it (it shouldn't anyway).
How do I tell Qt Creator where to build my application? I didn't find it anywhere and setting the DESTDIR variable isn't helping.
THE SOLUTION:
Deleting the .pro.user file made Qt Creator build the application to the directory specified in DESTDIR

I was battling with the same thing. What helped eventually was resetting the default build directory here:
