Problem of generating depth image for self-localization

[xz1cv]

I got some problems to generate the depth image using proj_point_cloud.py.

First, the problem is about GLEW:

Failed to initialize GLEW Missing GL version.

Segmentation fault (core dumped).

Then, I fix the link problem of GLEW, but the shader cannot be compiled.

The depth result is not correct as well, all the values are 299.7050.

How can I get the depth image? Thank you!

Is this due to the version of you lib in opengl is not compatible with that used in our case?

glxinfo | grep "OpenGL version"

we have version 4.5.0
