Yes you can, although obviously some (e.g. AIS) of the functionality is missing.
However things like building geometry and traversing topological structure is fully functional without the need for a graphics card.

Just out of curiosity, what do you intend to do?

Thank you for your answer.
I have a laptop and I was thinking install opencascade to learn but this machine does not have video card. The System requirements page of this site shows that you need video card: GeForce. Then I had the doubt.

Best regards,
Gustavo.

Hi Gustavo,

Keep in mind that while you "can" install OpenCascade without a graphics card you should take care of the compilation flags if you compile from source. The least you have to do is compile without openGL support. It is also very difficult to learn OpenCascade without the access to the visualization part. In particular it is a pitty that you cannot run draw (see thug.pdf) in the doc/OverView folder. Many OpenCascade features are explained there an you can play with them interactively.

I also don't think you really need a GeForce. It is probably recommended, but any recently new videocard should be sufficient.

On Unix it is not possible to build OpenCASCADE without X11, see

You can install OpenCASCADE regardless of whether the laptop has a graphics card or not. You can even use the visualization part of it. As long as your laptop has a display mechanism it will display the graphics too. However the display quality and graphics performance will be very frustrating since all the opengl calls would be executed using the software implementation.
