[SOLVED] Error: Could not find either Qt5 or Qt6

[Alex]

I follow all the steps to install Sofa on Macos.

I encountered the following error when trying to configure a makefile with CMake. I have installed the newest Qt, and used the troubleshooting “CMAKE_PREFIX_PATH=/home/tongjia/Qt/6.2.2/gcc_64”, but that didn’t work. Can somebody help me out?

Hey @ztjsofa

On macos with Qt5 installed using the Qt installer in $HOME/Qt/5.15.2, I usually build SOFA using:

git clone https://github.com/sofa-framework/sofa.git
cmake -S sofa -B sofa/build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DQt5_DIR=$HOME/Qt/5.15.2/clang_64/lib/cmake/Qt5
cmake --build sofa/build
cmake --install sofa/build

You will have to change $HOME/Qt/5.15.2 for your Qt path. I have not tested it with Qt6, but Qt5 works.

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.

Hey @ztjsofa

are you running SOFA from python?
The black background is due to the fact you need to load the CImgPlugin.
In python: SofaRuntime.importPlugin("CImgPlugin")

Else are simulations running fine?

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!

[Hugo]

Hey @ztjsofa

Could you then tell me which command do you run?

Best

Hugo

[Alex]

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.

Hey @ztjsofa

Could you make a screenshot of the full screen to see what you see?
It will help, thanks.

Hugo

[Alex]

Hey @hugo

Sure, here is the screenshot.

Hey Alex,

What version of Qt are you using?

Also, can you try with both viewer to see if they both have a black output?

QtViewer:
runSofa -g qtviewer

QglViewer:
runSofa -g qglviewer

[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 @ztjsofa

Have you tried as given in the log comment (Available GUIs: {batch qglviewer qt}) to run instead:

runSofa -g qglviewer or runSofa -g qt

Best

Hugo

[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

[Hugo]

Hey @ztjsofa

It may be related that you are on MacOS (12). MacOS 11.6 works well though,or are you maybe running SOFA in a virtual machine?

Best,

Hugo

[Alex]

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

[Hugo]

Great to hear @ztjsofa!

Looking forward to your next steps!
