Why do I get the error “Unable to determine the execution environment” when running the “aocl version” command in the Intel SDK for OpenCL?

Environment

    Intel® Quartus® Prime Pro Edition
    Intel® Quartus® Prime Standard Edition
    Intel® FPGA SDK for OpenCL™ Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to an issue in version 18.1.0 of the FPGA Runtime Environment for OpenCL™, the  command “aocl version” will produce the following errors:

aocl: Unable to determine the execution environment of the FPGA Runtime Environment for OpenCL(TM).
aocl:   Detailed error: Could not find SDK internal libraries directory /opt/intel/intelFPGA_pro/18.1/aclrte-linux64/linux64/lib
aocl:   Detailed error: Could not determine the path to SDK internal libraries

Resolution

The workaround is to run the following command to create the directory that the command is looking for.

$ mkdir -p $INTELFPGAOCLSDKROOT/linux64/lib  

 

This problem is fixed beginning with the Quartus® Prime Software version18.1.1
