Error: Unable to rewrite SYCL IR file

[aidanom1]

Hi there,

I'm building DPC++ for the S10 FPGA and I'm getting the error in the subject. Full command is in the logfile. My supicion is that it is due to the the following 

clang-offload-bundler -type=ao -targets=host-x86_64-unknown-linux-gnu -input=/home/u177770/gsl/lib/libgsl.a -check-section -base-temp-dir=/home/u177770/tmp/icpx-458e49
clang-offload-bundler -type=o -targets=sycl-spir64-unknown-unknown -input=CMakeFiles/optPricer.profile.dir/fp2bin.cpp.o -check-section -base-temp-dir=/home/u177770/tmp/icpx-458e49

Where the GSL library differs in target to the C++ object files.

Any help appreciated!

Hi, I tried building one of the oneAPI samples. Here is my log

Hi @aidanom1,

Thank you for posting in Intel community forum and hope all is well.

From the logs that you have shown, it seems that you are trying to compile the design for FPGA hardware, and which it will it would requires hardware of S10 or A10.

And from the node that you have accessed, it just a compile node which does not have hardware.

Hence would suggest to changed to a node with hardware to try the compilation.

Hope that clarify.

Best Wishes
