Hi!

Sorry for my late reply. I preload libGLX_mesa.so.0 , and then run  the code on the arm machine is ok.
I tried to debug it, and then I found something different. The parameter of __glXLookupVendorByName is NVIDIA instead of mesa, it will dlopen libGLX_nvidia.so.0,
but my Graphics Card is AMD, only IibGLX_mesa.so.0 can be found locally, so __glXLookupVendorByName failed.

(gdb) b libglxmapping.c:574
Breakpoint 4 at 0xfffff3a993d0: file ../../../src/GLX/libglxmapping.c, line 574.
(gdb) r

(gdb) b libglxmapping.c:430

(gdb) p filename
$12 = 0xaaaaab1ecc40 "libGLX_nvidia.so.0"
(gdb) 

I tried to continue debug, but I didn't find why filename is nvidia. 
 If you could please shed some light on this topic, I would really appreciate it.
Thank you in advance.
