[rpr-1.7] Blank page when trying to render ('Check log for details')

This is a similar issue to ProRender for blender Rendering not showing anything,[pc, windows 10, all drivers up to date and my machine meets the system requirements] but it is giving error, "Check Log for details" please help fix this , but

on Linux and with Nvidia card

First I must mention that this is on a unsupported Linux distribution, so I don't expect the developers attention (I suspect they have their hands full already),

this is more of a possible bug report for reference.

Some version info:

   -  RPR version 1.7.212 (core 1.312)

     - Nvidia GT-640 (yes, I know , can't afford AMD at the moment) binary driver 396.54

     clinfo shows it as OpenCL-1.2 capable

 

Installing rpr was pretty straightforward:

- extract the .run file

- install the addon from within Blender

- activate it

- add RPR_MATERIAL_LIBRARY_PATH as a environment variable

(couldn't figure out the proper path to copy it too, rpr in Blender kept complaining that it can't find it

without setting env variable).

Since the version of Blender (2.79 built from upstream master branch (I can dig up the exact commit, if you are interested)) is

using system python3, I removed cffi_backend.cpython-35m-x86_64-linux-gnu.so and libffi-72499c49.so.6.0.4

libraries from rprblender directory (system versions are 1.3.1 and 3.2.1).

Btw, I've seen in install.py  embree and openimageio as dependencies.

I do have openimageio-1.8.14 installed, but no embree.

 

Two issues:

- Can't apply any materials (object just turns bright white)

- When I try to render, blank page with the 'Check log for details' shows

I think this is the relevant portion from the rprblender.log
