I need to develop Qt and command line software for the BeagleBone Black and Raspberry Pi-2. Ideally I wish to use QtCreator as I am accustomed to it, but in any case I need to use QtDesigner for GUI work.
I have spent days trawling through articles, going around in circles and getting nowhere.
The Raspberry Pi-2 has Raspbian/Jessie installed together with Qt 5.2.3. I can design, compile and run Qt desktop applications on this. Of course compilation is slow and not really usable for development work.
To try and keep matters simple, I downloaded qt-opensource-windows-x86-android-5.3.2.exe and installed that on my Windows 7 (64-bit) system. My belief is that this Qt install is the same version as the Qt on the Pi-2 and already contains the ARM7 library files required for cross-compiling. All that should be needed is a cross-compiler for Windows/ARM?
Windows/QtCreator complained in Tools > Options > Qt Versions about the Qt 5.3 for Android armv7 stating "No compiler can produce code for this Qt version...".
For a Windows/ARM cross-compiler I downloaded and installed Yagarto (yagarto-bu-2.23.1_gcc-4.7.2-c-c++_nl-1.20.0_gdb-7.5.1_eabi_20121222.exe). I figured I then just need to set the QtCreator compiler path in Tools > Options > Compilers and then things would start working. This is not the case.
Clearly I am missing something important and have managed to become confused by the number of not-quite-relevant articles I have read.
Is Yagarto the cross-compiler I need in this situation?
How do I define the compiler in QtCreator and get rid of the error?
Is there an easier way to set-up this stuff?
Thank you.
Details:
QtCreator 3.2.1 (Qt 5.3.2)
Windows 7 64-bit service pack 1
Edit:
I have just tried again using the GCC ARM Embedded ToolChain and GNU Make for Windows. The result is the same in that I cannot seem to configure the settings for QtCreator ARM7 and make it happy.

I would like to ask a question about VS2010 IDE environment with all the C++11 features. Currently we need to build our software where some libraries need C++11 all feature support but we are now still running VS2010 environment and currently we are not upgrading our VS2010 to VS2017 at this moment.
So Is there any way to build these library with alternative mentods like installing QT creator on Windows platform so that can use g++ 4.9.3 or later same as on linux ubuntu? I found some website mentioning about Cygwin installed on Windows but seems not clear how to do.
Thanks for your help!
The QT installer provides binary versions built with MinGW as well as MinGW itself, so just use those.
I'm trying to build a simple application with CUDA and I've been trying for hours on end and I just can't make it work on windows. nvcc absolutely refuses to compile without Visual Studio's compiler which doesn't support things I need. I tried building using nvcc with clang but It just asks me to use Visual Studio's compiler. I've also tried using clang directly since it now supports CUDA but I receive this error:
clang++.exe: error: Unsupported CUDA gpu architecture: compute_52
This makes no sense to me because I have the CUDA toolkit version 7.5 and my graphics card is a GTX 970 (two of them). I have googled this extensively and everywhere I come across the error the person always has is their CUDA toolkit is < 7.5. I'm on the brink of tears right now trying to get something as simple as VLA to work on this CUDA application and I just can't achieve it...
The CUDA windows toolchain requires the Visual Studio C++ compiler. You cannot use anything else on that platform. If the VS compiler doesn't support the language features you need within CUDA host code, you have no choice but to change platforms, or your expectations.
You can still potentially compile non-CUDA host code using another compiler and then link that code using NVCC and the VS toolchain.
Try to use clang-cl, --cubin=clang-cl.exe
It may be worth to work on a Linux VM or WSL2 within windows. As per the CUDA docs.
To compile new CUDA applications, a CUDA Toolkit for Linux x86 is
needed. CUDA Toolkit support for WSL is still in preview stage as
developer tools such as profilers are not available yet. However, CUDA
application development is fully supported in the WSL2 environment, as
a result, users should be able to compile new CUDA Linux applications
with the latest CUDA Toolkit for x86 Linux.
https://docs.nvidia.com/cuda/wsl-user-guide/index.html#:~:text=However%2C%20CUDA%20application%20development%20is,becomes%20available%20within%20WSL%202.
I want to have the same developing environment either in Linux and in Windows so I decided to use Qt Creator. But for some unknown reason I cannot trace my project in Qt Creator under Windows 7. I compile my program as DEBUG target, the resulting executable contains all debug info. After that I press F10 key to step over main function but instead of stepping it just brings program to run. Stepping into via F11 does the same thing.
Firstly I tried gdb shipped with MinGW but Qt Creator refused even to run it complaining that it should be Python capable. After that I have downloaded and installed gdb with Python support from
http://download.qt-project.org/development_releases/prebuilt/gdb/windows-7/qtcreator-gdb-7.4-MINGW32_NT-6.1-i686.tar.gz
as Qt Creator manual recommends but it just made that Qt Creator is able to start the debugger and nothing more, I could not do source level debugging anyway.
Qt Creator under Linux works fine with the same project, it traces, steps and shows the sources Ok. I run MinGW 4.8.1 and Qt Creator 3.1.1 under Windows 7 64bit and the same Qt Creator 3.1.1 version under Fedora Linux 64bit. How can I achieve source level debugging under Windows like under Linux I do?
The best thing is to use Visual studio express compiler and then install the windows debugging tools like specified here and configure qt-creator
Recent GDB builds shipped with MinGW are Python-enabled, and work out-of-the-box in Qt Creator. The link you found seems outdated.
I recently decided to upgrade from Qt 4.X to 5, though now it has only vs2010 supported. Whenever I start Qt Creator I get that there isn't any compiler (and there are no options in the settings to set one).
Question:
How do I download the vs2010 compiler? Do I have to download vs2010 itself? Will I get a debugger as well?
I have tried this suggestion, but Qt didn't pick up the compiler: Using Visual Studio as a Compiler for QT Creator
Sorry if this question have been asked before, but I have been unable to find a source that explains what I should do.
Seems like you didn't install MSVC yet. Get it from Microsoft website.
Than download sources from Nokia. Unpack them to a new folder e.g C:\QtSources and compile them with MSVC. This instructions are working just fine.
Finally add them to Qt Creator in
Tools -> Options -> Building -> Qt Versions
by poiting to your new qmake executable in
C:\QtSources\bin\qmake.exe
Hope Qt 5 will work with free Express Edition of MSVC.
You shouldn't need to re-compile Qt, as the SDK version is built with msvc2010 32-bit. For debugging, you may need to download the Windows SDK 8. Qt Creator may auto-detect your compiler and debugger, but if not, proceed as follows:
Under Options/Build & Run/Qt Versions, point to qmake.exe
Under Options/Build & Run/Kits, set "Qt Version" to the one you just created, and set your compiler and debugger
The compiler should be auto-detected if it's on your system.
The debugger is something like C:\Program Files\Windows Kits\8.0\Debuggers\x86\cdb.exe.
Good luck!
I am developing an app with GCC, mostly on Windows, until I got a crash that couldn't be debugged with the MinGW toolchain build I have. I installed a Linux VM, and debugged it there, which was possible, because the libstdc++ had the symbols I required.
I'm sure the Linux build of libstdc++ was a release (optimized version), because this would be normal to be installed for all apps to use. Same with the Windows version. But how can the Linux version have the necessary debug symbols built in, or if I ask the question I really want an answer to: how can I build GCC's libstdc++ so that I can get a useful stacktrace out of it, and still have it optimized? (note: I am able to recompile GCC/MinGW, so that's not an issue)
I know visual studio has both debug and release versions, but never heard of something like that for Linux. The debug symbols are always in seperate packages as I remember.
Info: I was using Arch linux with the plain GCC packages installed (no special debug versions explicitly selected).
I'll answer this one myself: you need to configure with
--with-stdcxx-debug
This will place a in lib/bin and lib/debug a shared and import library, which contains debug info.
