Problem on the viewer

[Tianci-Wen]

My current problem is that the glfwGetError function cannot be found in libimgui.so. I guess my glfw version (3.3.2-1) is wrong. I would like to ask what is your glfwversion? If possible, please also tell me your openglversion. Mine is OpenGL version string: 4.6.0 NVIDIA 535.161.07. Thank you again!

I fixed this issue after updating glfw to 3.3.10. But I'm also not sure about the minimum glfw version requirements. This version of glfw can be easily installed by following the commands:

wget https://codeload.github.com/glfw/glfw/tar.gz/refs/tags/3.3.10
cd glfw
mkdir build && cd build
cmake ..
make -j4
sudo make install
