Subject: Re: Parallella: OpenCL
Hello,
Both libraries are in /opt/adapteva/esdk/tools/host/armv7l/lib/ but I
already add this path to the LD_LIBRARY_PATH
echo $LD_LIBRARY_PATH
/opt/adapteva/esdk/tools/host/armv7l/lib/:/usr/local/browndeer/lib:/usr/local/lib:
What I should do now, try to make bcrypt run without opencl or downgrade
the browndeer sdk?.
