After your Intel® Arria® 10 GX FPGA Development Kit board is initialized for use with the Intel® FPGA SDK for OpenCL™ Offline Compiler, install the OpenCL* runtime driver, and run a diagnostic.

To install the OpenCL* runtime driver and run a diagnostic test:

1. Ensure that the AOCL_BOARD_PACKAGE_ROOT environment variable points to where you have the a10_ref board support package (BSP).
2. On Linux host systems, set the LD_LIBRARY_PATH environment variable as follows:

   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$INTELFPGAOCLSDKROOT/host/linux64/lib:$AOCL_BOARD_PACKAGE_ROOT/linux64/lib

3. Install the OpenCL* runtime driver by running the following command with root or administrator privileges:

   aocl install

   The command should produce output like the following example output:

   aocl install: Running install from /tools/aclboardpkg/altera_a10pciedk/16.0/linux64/libexec

   CAUTION:

   The aocl install command may fail in Ubuntu* 16.04, kernel 4.14 or newer version because of a problem with the installed PCIe* drivers. Refer to The aocl install command fails due to a problem with PCIe drivers for solution.
