Dpcpp compilation error message: clang-offload-bundler: error: file too small to be an archive

[Tse__Amon]

Hello Support Team,

I am testing OneAPI Dpcpp 2021.1 on Ubuntu 18.04:

Intel(R) oneAPI DPC++ Compiler 2021.1 (2020.10.0.1113)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /opt/intel/oneapi/compiler/2021.1.1/linux/bin

I made a test program with SYCL with CMake. Below are the generated compilation/link commands for FPGA emulator: (I put # comment for description)

# compile a C++ class to object file

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/dpcpp -DFPGA_EMULATOR -DUSE_DPCPP -Dsequential_EXPORTS -I../.. -g -fPIC -std=gnu++17 -MD -MT sequential/CMakeFiles/sequential.dir/iota_sequential.cpp.o -MF sequential/CMakeFiles/sequential.dir/iota_sequential.cpp.o.d -o sequential/CMakeFiles/sequential.dir/iota_sequential.cpp.o -c ../sequential/iota_sequential.cpp

# link the C++ class into shared lib

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/dpcpp -fPIC -g -shared -Wl,-soname,libsequential.so -o Debug-FPGA_EMULATOR/libsequential.so sequential/CMakeFiles/sequential.dir/iota_sequential.cpp.o

# compile the C++/SYCL class with FPGA emulator selector

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/dpcpp -DFPGA_EMULATOR -DUSE_DPCPP -g -fintelfpga -c CMakeDpcpp/parallel/iota_parallel.cpp -ICMakeDpcpp/.. -o CMakeDpcpp/build/parallel/iota_parallel.cpp.o

# compile the C++ main function, calling the C++ class and C++/SYCL class above 

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/dpcpp -DFPGA_EMULATOR -DUSE_DPCPP -I../.. -g -std=gnu++17 -MD -MT main/CMakeFiles/CMakeDpcpp.dir/main.cpp.o -MF main/CMakeFiles/CMakeDpcpp.dir/main.cpp.o.d -o main/CMakeFiles/CMakeDpcpp.dir/main.cpp.o -c ../main/main.cpp

# link the main.o shared lib and the C++/SYCL obj file to product the FPGA emulator executable

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/dpcpp -g -g -fintelfpga main/CMakeFiles/CMakeDpcpp.dir/main.cpp.o -o Debug-FPGA_EMULATOR/CMakeDpcpp.fpga_emu Debug-FPGA_EMULATOR/libsequential.so parallel/iota_parallel.cpp.o

The last command produces the executable but pop out two error messages:

clang-offload-bundler: error: file too small to be an archive
clang-offload-bundler: error: file too small to be an archive

Although there are two error messages, the executable CMakeDpcpp.fpga_emu is generated successfully and it is executed as expected successfully.

My question is: Do the error messages clang-offload-bundler matter?
