troubles using gpu samples in i.max6q board

lidinihao — Mon, 20 Mar 2017 01:44:10 GMT

with i.max6q board, kernel 3.14, i download gpu_sdk_v1.00.tar.gz to run some samples for test to take use of GPU. after compiling the sample codes, to run the object file, it reports error like "./01_SimpleTriangle: error while loading shared libraries: libGLESv1_CM.so.1: cannot open shared object file: No such file or directory"

i'm sure such dynamic libs exists on /usr/lib, also i use /etc/ld.so.conf and cmd "ldconfig" to make the location valid to get. but it still can not work. is there anyone know about this and give me some help??

Hello

Please check the list of dynamic libraries linked with libGLESv1_CM.so.1,

using ldd command.

Have a great day,
Yuri

Hi,

Just make a search for these missing libs using:

find / -name libGLESv1_CM.so.1

and then let the system know where the folder containing those libs is using:

export LD_LIBRARY_PATH=your_lib_dir

Hope this helps,

Marius

If you can't find the .so files on your linux target then you should search them on your yocto/linux host and copy them in the linux target rootfs and inform the system about them using LD_LIBRARY_PATH as above.
