ERROR: Unable to find Intel(R) FPGA OpenCL platform.

[manos_pavlidakis]

I have an Intel Arria 10 FPGA board and I have installed AOCL-pro-20.3.0.158-linux.tar and DE5ANET_DDR4_OpenCL_BSP_20.3.tar.gz. I have successfully programmed the FPGA, since aocl diagnose showed me that "DIAGNOSTIC_PASSED".  Also I compile a the bitstreams for vector_addition and fft. However, when I am trying to run the host code it shows me the following error

Initializing OpenCL
dlerror: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /opt/altera/intelFPGA/20.3/hld/host/linux64/lib/libintelocl_emu.so)

Are you using a supported operating system? It looks like your GLIBC is too old. Check Section 1.3 of this document for list of supported operating systems:
