Errors occur while making the sample below:
ubuntu@tegra-ubuntu:~/NVIDIA_CUDA-8.0_Samples/5_Simulations/nbody_opengles$ make

WARNING - libGLES.so not found, please install libGLES.so <<<
WARNING - egl.h not found, please install egl.h <<<
WARNING - eglext.h not found, please install eglext.h <<<
WARNING - gl31.h not found, please install gl31.h <<<

#1 Apparently, OpenGL ES 3.1 is missing. I have no idea how to choose mesa and tegra? An installation checklist is desired.

#2 warning egl is not found, but it can be found below:
ubuntu@tegra-ubuntu:~$ apt-cache search libegl
libegl1-mesa - free implementation of the EGL API – runtime
libegl1-mesa-dev - free implementation of the EGL API – development files
so, it seems mesa is preferable to tegra. Is it right? Need a complete tegra-like opengl packages be post installed?

Hi,

Sorry for the late reply, please try following command:

sudo apt-get install libegl1-mesa-dev
sudo apt-get install libgles2-mesa-dev
cd /usr/lib/aarch64-linux-gnu/
sudo ln -sf tegra-egl/libEGL.so libEGL.so

This will fix missing header issue and also make sure tx1 link to the correct library.(tegra-egl/libEGL.so)
