Due to a problem with the FPGA add-on for custom platforms in the Intel® oneAPI software version 2021.2, this error might be seen when compiling an Intel® Stratix® 10 FPGA SYCL kernel using the flat flow.
A patch is available to fix this problem for the Intel® oneAPI software version 2021.2. Download and install zip/tarball from the following links:
The zip/tarball directory structure should be relative to the FPGA install directory (eg. /opt/intel/oneapi/compiler/2021.2.0/linux/lib/oclfpga).
- Set file ownership to root (chown -R root:root)
- Set file permissions
- chmod -R 755
- chmod -R g-s
This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 21.2 and Intel® oneAPI software version 2021.3.
