Dpcpp++ unable to handle switch -MD -MT -MF with -fintelfpga

[Tse__Amon]

Hello Support Team,

I am trying to use cmake to generate build script for Dpcpp for FPGA target.

The following is a compilation command generated to compile a sycl cxx source code target for FPGA but the dpcpp returns error (running on Ubuntu 18.04):

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/dpcpp -DFPGA_EMULATOR -DUSE_DPCPP -I../.. -g -g -g -fintelfpga -std=gnu++17 -MD -MT parallel/CMakeFiles/parallel.dir/iota_parallel.cpp.o -MF parallel/CMakeFiles/parallel.dir/iota_parallel.cpp.o.d -o parallel/CMakeFiles/parallel.dir/iota_parallel.cpp.o -c ../parallel/iota_parallel.cpp
/opt/intel/oneapi/compiler/2021.1.1/linux/bin/clang-offload-bundler: error: number of input files and targets should match in bundling mode
dpcpp: error: clang-offload-bundler command failed with exit code 1 (use -v to see invocation)

If I remove manually the -MD -MT and -MF switches, then the compilation can be successfully completed.

A note here that dpcpp can work with -MD -MT -MF if -fintelfpga is absent (for sycl code not target for FPGA). 

May Intel engineer please follow.

Best Regards,

Amon

Hi Amon,

Thanks for reaching out to us.

We will contact the internal team for the exact reason behind the error.

For time being we have observed that if you remove the -c flag and directly provide the input file there was no error.

We will get back to you soon.

Regards

Hi Amon,

We have gone through your query and found that it is related to FPGA as there are no errors when -fintelfpga flag is removed.

Since your issue is related to FPGA, we have a dedicated forum for FPGA related issues.

We are redirecting this thread to FPGA Forum for faster response.

Have a Good day.

Thanks & Regards

Sorry for the late reply due to long holiday,

Do you mind to share with us the functionality -MD -MT and -MF switches ? This would be an enhancement to FPGA One API.
