How to make app bundle for macOS with OpenCV?

then I have this error

At which step?

[NintyS]

First error I got on this command "make clean", and second error I have on this "qmake -config release".

[jsulm]

I know how to fix it in Qt Creator

How did you fix it in QtCreator?

[NintyS]

I add to Build Environment PKG_CONFIG_PATH and modify PATH. ( I couldn't post it earlier because I don't have 1 point of reputation and I must wait every time 10 minutes ).

[jsulm]

@NintyS You can do exactly the same in the terminal, like:

export PKG_CONFIG_PATH=SOME_PATH

[NintyS]

Ok it works, but what about error with make clean? "qmake -config release" and "make" works but what with "make clean"? This commands is necessary? ( I will be asking about whole way of creating app bundle, because this isn't clear to me ).

[jsulm]

@NintyS If there is nothing to clean "make clean" will fail. It should work after make. "make clean" is used to delete build artefacts, for example if you want to rebuild completely.

[NintyS]

Here ( in tutorial ) is a "plugins" folder and I know I must create this directory myself, but this folder will be empty and in this tutorial is that I must use "make clean", "qmake -config release" and "make" so what I supposed to do? ( Can you give me a one point of reputation to I could send you reply faster? )

I know I must create this directory myself

According to the documentation this is not correct.
"When we built the Plug & Paint plugins, based on the DESTDIR variable in their .pro file, the plugins' .dylib files are in the plugins subdirectory under the plugandpaint directory. We just have to move this directory to the correct location."

Then how to create a plugin folder? There we go to folder with app "cd /path/to/Qt/examples/widgets/tools/plugandpaint/app" and this create new file .app "make clean && qmake -config release && make" so where is command for plugins folder?

[jsulm]

@NintyS This is stated in the link:
"This builds the core application. Use the following to build the plugins:"

cd ../plugandpaint/plugins
make clean
qmake -config release
make

[NintyS]

This don’t make any sense for me. Why I must go intro plugins directory if this directory don’t exist? Command „cd” set user position intro this directory.

[jsulm]

@NintyS There IS plugins directory inside the plugandpaint app. It should look like this:

app
plugins
plugandpaint.pro

This is what you have to do:

cd /path/to/Qt/examples/widgets/tools/plugandpaint/app

// Run qmake to create a new makefile for the application, and do a clean build to create the dynamically linked executable:

make clean
qmake -config release
make

// This builds the core application.
// Use the following to build the plugins:

cd ../plugandpaint/plugins
make clean
qmake -config release
make

[NintyS]

Do you want a screenshot?

[jsulm]

@NintyS Yes, pleas.
How did you install Qt? And did you install the examples?

[NintyS]

Yes, I install qt and examples but I don't do this on the example, just on my own project. There is screenshots.

[jsulm]

@NintyS Well, in that case I guess you do not have any own plug-ins, so simply skip that step.

[NintyS]

Oooo. Ok.

[NintyS]

Now I have another error: "/Applications/Mobile/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/objdump: error: 'QtGui.framework/QtGui': No such file or directory"

Why otool search framework there but not in Qt/version/clang/bin?

@NintyS Sorry, I'm not Mac user. From here somebody else should help you. @SGaist do you have an idea?
