I'm having a project in Qt Creator and I'm trying to port it into CLion but I found myself blocked into some problems. If any of you could help me to port this CMake project I would really appreciate it.
Qt Creator
So, here is my setup for the Qt Creator project first:
Qt: 5.14.2
Compiler: MSVC 2017 64-bits
Also, here are my custom paths and my build environment:
Also, the build (install) time in Qt Creator takes around 20-30minutes.
CLion
Now in terms of CLion and what I've tried here are the following.
and in terms of setting up the CMake:
I've also added the paths into Environment Variables from CLion
But the problem arises when I'm trying to compile the project.
I'm going to install the project via Build -> Install
After that, I need to wait for around 1h or more(even if in Qt Creator is going to take just 20-30min) to a point where the build will fail and I will receive the following error message
MASM : fatal error A1000: cannot open file : 4 [C:\PRJOJECT_NAME\build_clion\components\extern_crashpad\crashpad\util\crashpad_util.vcxproj]
but if I'm searching for that file, it exists in that folder which is specified. But the problem is that I don't understand why the same project if build with Qt Creator is working but not vice versa. Could any of you help me to understand what I'm doing wrong?
It looks like QT Creator is using Ninja as a generator and CLion is using MSVC.
Try -G Ninja in your CLion CMake Options text box. Make sure Ninja is in a path accessible by CMake.

I'm trying to compile and run an application on a MacBook using Qt Creator. There are no issues compiling the project, but when I try and run it, it seems to be unable to load a plugin.
Could not load the Qt platform plugin "cocoa" in "" even though it was found.
The application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
This error occurs both when trying to run the application from Qt Creator or via Finder. It seems to only happen when I use the CMake build system (no issues when using QMake), but my existing project that I need to deploy on MacOS uses CMake.
My steps to reproduce are:
Install a completely clean MacOS (no user data)
Install Xcode 11
Install CMake 3.15
Install Qt 5.13.1 MacOS package
Open QtCreator->New Project->Qt Quick Application - Scroll
Set build system to CMake (important)
Compile and notice error
I am using:
Qt 5.13.1
macOS Catalina 10.15
Apple Clang 11
I recognize that for final user deployment I will need to use the macqtdeploy tool to copy the Qt libraries to the executable folder, but I should be able to run my app from QtCreator without doing this? Especially as it works fine when using QMake.
So it ended up being some kind of name resolution thing where Qt Creator couldn't decide whether to use the debug or release versions of the framework. Supplying DYLD_IMAGE_SUFFIX=_debug fixed this (add this to the environment section under Kits).
I create empty C++ project in QT Creator using cmake. After some menus where I choose "cmake" as a building tool I see a project hierarchy:
- MyTestCMake2
- CMakeLists.txt
(New Project -> Non-Qt Project -> Plain C++ Application -> checked CMake for building system)
And that's all! It's strange but QTCreator opens main.cpp with some C++ code but QTCreator tells me that this file does not a part of my project. I try to add main.cpp manually to MyTestCMake2 project but I can't do it. It's disabled.
CMakeLists.txt content is:
cmake_minimum_required(VERSION 2.8)
project(MyTestCMake2)
add_executable(${PROJECT_NAME} "main.cpp")
I try to run cmake with: Build -> Run CMake but nothing happens. What's wrong? Why QTCreator doesn't work with CMake properly?
My env is:
cmake: 3.9.1
Qt Creator: 4.3.1 (Qt: 5.9.1)
Mac OS Sierra 10.12.5
SOLVED
I've upgraded Qt Creator to 4.4 and it worked out of the box! I did the same steps as before but now it works without any problems! What a magic.

Sometimes the mixed QT 5.x installation breaks the kits. Several kits starts to show a warning in the kit popup message balloon (Tools->Options->Kits->Kits: Auto-detected/Manual) about unsupported generator cmake server mode (cmake -E command line option).
Seems only behind the cmake server mode the Qt Creator can properly build the Projects pane.
The only way I could get it fixed is complete QT uninstall before install. Even the last QT 5.x minor version can break the kits (5.12.12 at the moment).
faced with an issue during qt creator using (re-build action):
Running steps for project algolist... Could not start process "" clean
Error while building/deploying project algolist (kit: MSVC2015)
Environment settings:
QtCreator 3.5.1
Windows 10 (and SDK forWin10)
visual c++ compiler with libraries version 19
I do not use any qt libraries in a project, and havew an installed qt kit just for qmake support (qmake is a build tool for my project)
all compiler's settings are manual via INCLUDE/LIB/PATH. and this configuration works on my other machine, can't find a differences and the message above doesn't look informative, could you someone explain me please what this mean ?
thanks
as fas as I use manual compiler configuration , I had to specify nmake path there as well. so this fix in compiler config fixed my problem
sorry for my inattention
Because I am not a Java enthusiast, I decided to use C++ and Qt for one of my projects. However, I came across the big cross-compiling Qt problem, and I am unable to produce an .exe file for Windows users.
My setup
Linux Ubuntu 12.04, with Wine and Qt. qmake -v gives the following output :
QMake version 2.01a
Using Qt version 4.8.1 in /usr/lib/x86_64-linux-gnu
I also have a MinGW32 compiler, which can be found at /usr/bin/i586-mingw32msvc-g++. My Wine drive_c folder contains the following Qt directories :
$HOME/.wine/drive_c/Qt/Qt5.2.0/5.2.0/Src
$HOME/.wine/drive_c/Qt/Qt5.2.0/5.2.0/mingw48_32
The mingw48_32 directory contains the necessary include/ and lib/ directories, which are used in my mkspec file, /usr/share/qt4/mkspecs/win32-x-g++/qmake.conf :
QMAKE_INCDIR_QT = /home/me/.wine/drive_c/Qt/Qt5.2.0/5.2.0/mingw48_32/include
QMAKE_LIBDIR_QT = /home/me/.wine/drive_c/Qt/Qt5.2.0/5.2.0/mingw48_32/lib
The problem
According to most guides I've found about Qt cross-compiling, my setup should be enough to run a simple :
qmake -spec win32-x-g++
make
wine /path/to/my/application.exe
But... nothing's linked. QApplication and every other symbol I use in my program are "not found". No QApplication, no QPushButton, no connect(), no SIGNAL(), no SLOT()...
My objective here is to successfully configure QtCreator to use this setup (in an independent build configuration), so that it can build a Linux executable (through the first and working configuration), and a Win32 .exe (through the MinGW setup above). However, I cannot modify a single build step in QtCreator :
Cannot add a "MinGW" toolchain : it is not available in the "Add" dropdown list.
Cannot change the -spec parameter value in the project build configurations panel. The field is non-editable.
Despite guides and solutions I found all over the Internet, my only solution so far is to send my source code to a virtual Windows machine, and have it create a new project with it. On this VM, I could probably compile for Windows... But of course, this doesn't actually sound like a real "solution" to me...
Is there any way Qt(Creator) has finally made cross-compiling easier now ? I'm getting a bit tired of "symbol not found" errors...
First,
sudo apt-get install mingw-w64
Then, check if Qt Creator finds the toolchain.
Next, until Ubuntu starts providing a mingw-w64-qt package, download the Qt source and build it. This is bound to get messy, and maybe even the simplest thing to do is to install WINE and use a Windows Qt version.
I just started using Qt Creator for creating C++ GUI programs. I just downloaded it and installed it, but the compiling process is throwing me errors. When I try to compile my project (very simple, just a QLabel on the screen...it's my first project) it comes up with the error:
qtcreator_ctrlc_stub: Command line failed:

I hunted around for an answer here and here and a couple other places but I'm just confused about the whole thing. I have a couple of ideas of my own but I don't know how to try my ideas. Here are some of my ideas:
1) MinGW isn't in the path or isn't installed
But, if it isn't in the path, how do I put it in? Where is it? I have Code Blocks installed which has MinGW installed, so could I maybe use it from there?
2) the make file is messed up somehow
Again, what could be wrong and how could I fix it?
3) Qt Creator isn't installed correctly.
Obviously, re-install it, but I want to make sure all other options are tried before, because it took me a very long time to download.
I apologize if I'm sounding noobish or it's a stupid question, but I really am confused with all of this. Please be patient with me and try to explain things well and thoroughly. I'm using Windows 8.1 and downloaded the offline installer. Thanks in advance.
UPDATE
Here is a screenshot of my Qt, how can I tell if it is the visual studio or minGW version?
UPDATE
Here is my MinGW Folder in CodeBlocks. Is this the folder with the compiler or is it something else?
For your ideas:
1: if you downloaded from qtproject with binary. then qt and qt creator should be installed under the C:\Qt\Qt5.1.1 then corresponding minGW should be stay in C:\Qt\Qt5.1.1\Tools\mingw48_32\bin\gcc.exe
this is the directory you need. Remember, QtCreator needs two tools to make sure your project and compile and run, qmake and compiler.
Qmake is tool help you translate .pro file into makefile,
compiler (gcc) minGW use gcc to run the makefile, compile your code to binary.
where to figure out tools you are using are correct?
---> qtcreator --> Tools -> Build&Run -> Kits
in here You should be able find different kits, of course you maybe have only one.
Select one, Double check the Qt Version and Compiler is the one you wish to use.
click Manage next to compiler, Every compiler in the Auto-detect should be ok to use.
If you don't see anyone, add one, click Add, MinGW, put C:\Qt\Qt5.1.1\Tools\mingw48_32\bin\gcc.exe like into path. ABI should auto-set depends on your environment.
Answer to your second question, what's wrong with your makefile, no one knows, you should check your .pro, usually makefile are generated by qmake xx.pro. Double check your .pro file and re-run qmake will solve the problem.
in tools->options->build&run check if minGW is actually there in the compiler and kit list
in the project tab (on the left hand side) you can set the environment for the build click the PATH value and add the path to minGW to it (you may need to add a lib and include var so the standard library gets added)
re run qmake from the build menu
double check you have the correct version it looks like you have the visual studio Qt not the minGW version,
Terminal:(in Linux)
sudo apt-get install build-essential cmake libqt4-dev
i'm sorry i dont know why this code works,but i have the same problem in linux and this code worked.
