Imgui does not draw under MacOS

[rezzeted]

Initially I encountered this in version 2.6 simply using imgui-sfml from the vcpkg package manager. Then I tried to take the 3.0 version of sfml-imgui, made a local fork of vcpkg and updated sfml in it to version 3.0.0. This did not change anything, in the minimal example I see a green circle that is drawn using sfml, but I do not see any windows from imgui, nothing at all.
Is there any possibility that should be taken into account for MacOS(M1 version)?

macOS support (both ARM and Intel) exists. I personally use ImGui-SFML on macOS. Can you share a minimum reproducible example for me to test? Also please share screenshots. I can't picture what you're describing. The more details the better or else there's not much I can do.

[rezzeted]

Sure. I took the imgui-sfml repository as a starting point, then connected my fork of vcpkg as a submodule and updated sfml to version 3 in it, maybe a little crookedly and I didn't take into account some build options (static or dynamic), but my goal was to get the final result as quickly as possible. Everything is fine on Windows. It builds on Mac, but as you can see in the screenshot there is nothing except the basic sfml shape (green circle).

Instructions.

1. clone the repository
2. Update the submodule (submodule init, submodule update, etc)
3. Go to the vcpkg folder and run the bootstrap-vcpkg.sh script
4. Run build.sh (probably a bad name for a script that will create xcodeproject, but what it is)
5. Open the project in the _intermediate_64 folder and run the minimal example

You might be confused that I am using another account's repository. I created a second account for a channel with programming tutorials.

Can you share your C++ code? I'll try building and running it.

Yes. It is in repo with all dependency https://github.com/icecampus/imgui-sfml

I use the version of sflm from their repository tagged 3.0.0

Is it this file? Sending me a link to the entire repo is a bit imprecise. I'm not sure exactly what file you have in mind.

[rezzeted]

Yes, it is, but I didn't make any changes on it.

Sorry, this is my first time participating in a discussion on GitHub.

[ChrisThrasher]

I just built the example and ran it on macOS. Everything looks fine to me. Perhaps the issue lies in the way you're using Vcpkg or otherwise building the project. I'm not really sure.

I suspect several possible problems:

1. incompatibility with the SFML version (very low probability, because I used tested versions of packages from the master branch of the VCPK, even though there was a 2.6 branch)
2. Some subtlety with setting up the build specifically for MacOS, it is necessary to specify specific permissions in the project or use special keys.

[rezzeted]

Maybe you have a repository with sfml and cmake build scripts? I would try it on your version and then analyze the difference in the project setup.

[ChrisThrasher]

I'm just using all the normal released code. I'm using an unmodified version of ImGui-SFML and an unmodified version of SFML. It's as simple as that. I just built ImGui-SFML and ran the minimal example. I don't have a repo of special scripts. All the differences can be attributed to the changes you made.

How did you install SFML?

[ChrisThrasher]

I built SFML 3.0.0's install target. If you want to talk more about your build issues, I encourage you to join the SFML Discord server.

Thank you for your answers, I will try your option and write about the results a little later.
