Building Qt Creator for windows 10

[fryn3]

I downloaded the source of Qt Creator.

Successfully assembled using commands:

qmake path_to_source\qtcreator.pro
mingw32-make -j4

When I start qtcreator.exe, I getting errors

Can't find files:

Qt5Network.dll
Qt5Gui.dll
Qt5Core.dll
Qt5Widgets.dll

To fix this, I copy the created lib, bin, share folders to the folder where Qt is installed, replacing the files.
Next time when I try to start qtcreator.exe the program displays a message about the absence of files:

libgcc_s_dw2-1.dll
libstdc++6.dll
libwinpthread-1.dll

I moved it to a folder C:/Qt/Tools/QtCreator/bin, where is the assembled creator. After that, the following errors occur:

qtcreator.exe - entry point not found

And now I think that I was doing something wrong. Help!

@fryn3 Aren't you missing

make install

?
Also, did you already have an installation of QtCreator in C:/Qt/Tools/QtCreator/bin?

[fryn3]

@jsulm Please tell me where I had to enter make install.
Yes, I have installed Qt Creator (MSVC 2015, 32 bit), I need a build for MinGW.

in the same place you called make.

"Yes, I have installed Qt Creator (MSVC 2015, 32 bit), I need a build for MinGW." - so, you now try to overwrite QtCreator built with MSVC 2015 with your own build?! This, for sure, is not going to work. You're mixing your own binaries with Qt libs built with MSVC 2015.
Do "make install" and start it from there.

May I ask you why you need QtCreator built with MinGW?

[fryn3]

@jsulm can't find comand make.
I need QtCreator built with MinGW for making own widgets.

No you don't. You can use prebuilt Qt Creator with any Qt version: both MinGW and MSVC work.

Hi,

@jsulm was referring to the mingw32-make command.

[fryn3]

@sierdzio, @sierdzio, @SGaist thanks, now installing.
@sierdzio The video in youtube has instructions for makeing own widgets.
If I try to connect my widget(which is assembled minGW) to QT(MSVC), I see a error message: the specified procedure was not found.

Ah, ok now I understand. You may need your own build of Qt Creator then, indeed.

[jsulm]

@fryn3 You could use Visual Studio Community (which is free) to build your widgets and use them in QtCreator.

[fryn3]

@jsulm I installed. What's next?
When I start qtcreator.exe, I getting same errors

Can't find files:

Qt5Network.dll
Qt5Gui.dll
Qt5Core.dll
Qt5Widgets.dll

libgcc_s_dw2-1.dll
libstdc++6.dll
libwinpthread-1.dll

qtcreator.exe - entry point not found

[jsulm]

@fryn3 Are you sure you're starting the one you built from the location where it was installed?

[fryn3]

@jsulm absolutely. I built and installed in C:\QtCreator\build\. QtCreater(MSVC) installed is in C:\Qt\Tools\QtCreator.
I'm trying to run C:\QtCreator\build\bin\qtcreator.exe.

[jsulm]

@fryn3 Then try to copy the missing libraries into the bin directory.

[fryn3]

@jsulm I tried.

1. Copy to C:\QtCreator\build\bin\

• Qt5Network.dll
• Qt5Gui.dll
• Qt5Core.dll
• Qt5Widgets.dll

2. I get errors:
   Can't find files: libgcc_s_dw2-1.dll, libstdc++6.dll, libwinpthread-1.dll
3. Copy to C:\QtCreator\build\bin\

• libgcc_s_dw2-1.dll
• libstdc++6.dll
• libwinpthread-1.dll

4. I get error:
   Can't find file: Qt5Qml.dll.
5. Copy to C:\QtCreator\build\bin\ Qt5Qml.dll file.
6. I get errors: qtcreator.exe - entry point not found

@fryn3 You're copying Qt libraries from MinGW Qt you used to build QtCreator, right? Also, did you check where "*make install" installed QtCreator?
You can use this tool to deploy your QtCreator: http://doc.qt.io/qt-5/windows-deployment.html
