'glUniform1i identifier not found' error when running nanogui with GLFW

[nikhilanayak]

Hi there. I'm trying to use nanogui with an existing GLFW project. To start, I am just using the example. However, when I run it, I get the error glUniform1i identifier not found from glutil.h. Any idea what this means?

Edit: I looked at another issue with a similar comment and they suggested commenting out that line. After doing so, I get this error: https://imgur.com/a/0oHE7Zm

Second Edit: Okay, I realized I need to compile the library to use it. However, when I initialize a screen, it becomes fully black.

Have you solved the problem about glunifrom1i? I have the same problem
