General Information Flags

The following table summarizes all flags that you can use to obtain general information on the software, compiler, and boards:

NOTE:

The Intel FPGA SDK for OpenCL™ includes two sets of command options: the SDK utility commands (aocl <command_option>) and the Intel® FPGA SDK for OpenCL™ Offline Compiler commands (aoc <command_option>). SYCL* also provides the aocl utility command.

OpenCL SYCL Description
aocl version aocl version Displays the version of the Intel® FPGA SDK for OpenCL™.
aoc -version icpx -fsycl --version Displays the compiler version.
aoc -help or

aoc -h

 icpx -fsycl -help Displays all supported compiler options.
icpx -fsycl -fsycl-help=fpga Prints out FPGA-specific options for the icpx command.
aocl -help <command_option> aocl -help <command_option> Displays information for aocl command options.
aocl env Perform these steps:
  1. Extract the .aocx file from the binary using the following command: 
    $INTELFPGAOCLSDKROOT/host/linux64/bin/aocl-extract-aocx
  2. Run the aocl env command on the extracted .aocx file.

Displays the compiler's input arguments and the environment for a compiled FPGA design.
