Displaying text using OpenGL +Cuda

[saranyasathees.111]

Hi,

Is there any predefined packages which support displaying text using Jetson Nano?
I want to display text on the HDMI display and i am using Cuda + openGL interop for rendering some symbols.Is there any method to render text/alphabets as well?

Thanks in advance

Hi,

Can I use freetype which comes with the nano installation to render some basic texts on my display?Is it not possible?

I started with #include<ft2build.h> and it throws a fatal error even after giving path in Library.Am i doing it wrong ?

Any insights would be helpful.
