How to use vTracer

I would like to use vTracer to debug our OpenGLES application.

I have checked i.MX_Graphics_User's_Guide.pdf and vTracer_Linux.txt which getting from vtktools.

However, I could not solve my issue. Please give me any advice to use vTracer tool.


<My environment>

Board : SABRE-SDB (i.MX6DL)

Linux BSP : L4.1.15_2.0.0_ga

VTK TOOL : L4.1.15_2.0.0-ga_gpu-tools.tar.gz


<Test Procedure>

I copied following files into rootfs of target board.

- = copy to /usr/lib/

- = copy to /usr/lib/

- vtracer.conf = copy to /opt/viv_samples/vdk/


I executed following commands.

# export VIV_TRACE=2

# export LD_PRELOAD=/usr/lib/

# cd /opt/viv_samples/vdk

# ./tutorial4_es20


Then, I got following error.

# ./tutorial4_es20
vtracer: Initializing VIVANTE vTracer.
vtracer: vTracer build: Dec 31 2015 20:06:25
vtracer: Reading configuration file at vtracer.conf for pid: 790
vtracer: cmdline: ? matches current process. tracing enabled
vtracer: startFrame: 0 endFrame: 0
Segmentation fault



How do I fix my settings to use vTracer?
