Hey @hugo,

I deleted everything and repeated the same installation process, this time with Qt 5.12.0, and the problem is solved. I still don’t know why but at least I am good for now. Many thanks for all replies from you and @jnbrunet 🙂

Best,
Alex

Hey @hugo,

Yes, I did, but it didn’t work either.

I really don’t know what is wrong. Is this “black output” a known issue?

Best,
Alex

Hi @jnbrunet

I am using Qt 5.15.2. It still has a black output when I use QglViewer.

When using the QtViewer, I met the following error and Sofa did not run.

[ERROR]   [GUIManager] GUI 'qtviewer' creation failed.

Hey @hugo

Sure, here is the screenshot.

Hey @hugo

I followed the steps in this link and the commands @jnbrunet told me to install Sofa. Then I go to the directory “build” in the terminal, and use “bin/runSofa” to run Sofa, which then shows a black background.

Best

Hi @hugo

I am running Sofa from the terminal on MacOS. I am not sure whether I am using python or not. (I am not an IT person.) Could you provide more specific steps to load the CImgPlugin, like what command and when to input in the terminal?

Many thanks!

Hi @jnbrunet

Appreciate your help. I have successfully installed Sofa with your suggestion. However, I only saw a black background in the animation region, instead of the caduceus animation. I opened several other demo scenes and saw the same (black) thing.

Also, the file “runSofa” I got is an “Alias” type, instead of an executable. I guess that doesn’t matter, since I can still open it in the terminal?

Below are the messages when running Safa.
