Due to a problem with the FPGA add-on for custom platforms in the Intel® oneAPI software version 2021.2, this error may be seen when compiling an Intel® Stratix® 10 SYCL kernel using the import flow
A patch is available to fix this problem for the Intel® oneAPI software version 2021.2. Download and install zip/tarball from the link below
The zip/tarball directory structure should be relative to the FPGA install directory (eg. /opt/intel/oneapi/compiler/2021.2.0/linux/lib/oclfpga).
1) Set file ownership to root (chown -R root:root)
2) Set file permissions
a) chmod -R 755
b) chmod -R g-s
This patch is scheduled to be included in a future release of the Intel® oneAPI software.
