Tested in Ubuntu 15.04 on a Tegra X1 system.</pre><pre style="white-space: pre-wrap;">Does this (Difference in GLES support on aarch64 and armhf) have a reason? How can I solve this issue, regarding the fact that I use GLES based source code and on Tegra X1 only GLES libraries exist?</pre><pre style="white-space: pre-wrap;"> </pre><pre style="white-space: pre-wrap;">Licheng Ma</pre><div> </div><div></div>
