Why i got error in building qt 3d studio?

SGaist

Hi,

If you are using your distribution Qt packages, you shall install the "-private" variants as well.

EmadDeve20

Hi @SGaist thank you for your answer :D
what is private package?
you can send me link for private package?

this link can help me?

SGaist

Which distribution are you using ?

EmadDeve20

ubuntu 20

SGaist

Then look for "qtdeclarative5-private-dev" and friends.

EmadDeve20

actually its works thanks!
i installed these packages:
sudo apt install qtbase5-gles-dev qtbase5-private-dev qtdeclarative5-private-dev

but after finishing install i got this message in my terminal:

Some of the required modules (qtHaveModule(opengl)) are not available. Skipped.

So I tried to find a package like that but I did not use it but failed :(

SGaist

@EmadDeve20 said in Why i got error in building qt 3d studio?:

qtbase5-gles-dev

Why this one ?
I think you want to use the desktop OpenGL variant.

EmadDeve20

Because I had an error before installing this ‍‍‍‍qtbase5-gles-dev package! So what is this package? Isn't this good for me?

EmadDeve20

Yes, I'm right when I delete this package, I'm having trouble making it!

SGaist

OpenGL ES is targeted at embedded system although it can also be used with desktop GPUs.

Which error do you get ?
Did you try from a clean state after adding the new packages ?

EmadDeve20

Aha ...
so right now i remove this qtbase5-gles-dev package. so when i try build it in my terminal i getting this message:

sudo make
Some of the required modules (qtHaveModule(opengl)) are not available. Skipped.

but when i tried to build it in qt creator i getting this message error:

so after this error i go to check my GPU installed or not!
I have not seen any drivers for my GPU since then! So I installed and then tried to rebuild and the error message was:

sudo apt install qt3d5-*

Did you clean again in between ?
Are you building from the archive sources or from a git clone ?

EmadDeve20

Yes, I cleaned again and I use git clone!

I myself do not know where the problem really is, I was confused! I wanted qt 3d for the company I work for. I'm building a working interface to control a robot whose prototype has already been built. But my company wants a nicer version. My boss showed me a sample of it and I thought it was probably made with qt 3d so I tried to install it.

Do you think this ui is made with qt 3d?

SGaist

Could be, or it could also be the Unreal Engine.

I just realized that you wrote Qt3D and Qt 3D Studio and both are two different things.

So your issue is currently to build the module.

Which exact version are you trying to build ?
Which version of Qt do you have installed ?
Since you are using the package of your distribution, why not install the Qt3D package ?

EmadDeve20

Well, in fact, if I want to use a 3D model in qt 3d, shouldn't I build that model in qt 3d studio?

so i can use juts code for create a robot model like this link: https://www.instagram.com/p/CR3HPScCzkJ/?

EmadDeve20

oh i got my answer! we can use blender application for 3d robot model!
Is qt 3d like a blender??

SGaist

No, blender is a full featured 3D modeling application.

If your talking about the Qt3D module, it can be used to build such applications.

EmadDeve20

I can load and use a model from a blender in qt 3d؟
You saw that robot inside the ui, right? I want to know how to build that robot!

SGaist
