You can comment out this line: /home/cxx/wzw/third-party/Pangolin/include/pangolin/gl/gl.h:173:29

@yuxng I also have this problem and what do you mean by comment out? if you mean comment in file gl.h, it will be huge work to do as there are a lot of private function in this file, each one of them will evoke an error, so do you think it might be the reason of wrong version of opengl or pangolin?

Hi @yuxng, Do you have any solution for the second error : /home/cxx/wzw/third-party/Pangolin/include/pangolin/gl/gl.hpp:298:40: error: ‘glCopyImageSubData’ was not declared in this scope width, height, 1); ?

Also do you know where these errors might come from ? Could it be because I used the wrong Pangolin branch ?

Thanks

[TotoLulu94]

For those who have this issue, these errors can come from 2 things :

• Your OpenGL/Glew version isn't recent enough (glCopyImageSubData only implemented for OpenGL version >= 4.1)
• or, you have at least 2 directories GL and "pangolin/gl/glplatform.h" includes the wrong <GL/glew.h>.

Hi @TotoLulu94 ,so would upgrade opengl version solve this problem? which opengl version is required?

Update: My opengl version is:

OpenGL version string: 4.5.0 NVIDIA 384.130

I still got the same issue above, how to fix this?

Update: Solved this problem by changing the

<GL/glew.h>

in

pangolin/gl/glplatform.h

using

/usr/include/GL/glew.h

which was mentioned in https://github.com/stevenlovegrove/Pangolin/issues/268
