How can I cross-compile TVM for RISC-V on x86 Ubuntu 22.04.2

Troubleshooting
#1

I want to cross-compile TVM for RISC-V on x86 Ubuntu 22.04.2.

Environment:

TVM version: 0.13.0-dev0

LLVM : sudo apt install llvm, version: 14.0.0

GNU toolchain for RISC-V : sudo apt-get install gcc-riscv64-linux-gnu, version: 11.3.0

I turned off the “use_libbacktrace” option in the config.cmake file and disabled the “USE_ALTERNATIVE_LINKER” option in the CMakeLists.txt file.

TVM cross-compile for RISC-V

    cmake .. \
        -DCMAKE_SYSTEM_NAME=Linux \
        -DCMAKE_SYSTEM_VERSION=1 \
        -DCMAKE_C_COMPILER=/usr/bin/riscv64-linux-gnu-gcc \
        -DCMAKE_CXX_COMPILER=/usr/bin/riscv64-linux-gnu-g++ \
        -DCMAKE_FIND_ROOT_PATH=/usr/riscv64-linux-gnu \
        -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=NEVER \
        -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY \
        -DMACHINE_NAME=riscv64-linux-gnu

    make -j$(nproc)

Then I encountered the following error:

    /usr/lib/gcc-cross/riscv64-linux-gnu/11/../../../../riscv64-linux-gnu/bin/ld: /usr/lib/llvm-14/lib/libLLVM-14.so: error adding symbols: file in wrong format
    collect2: error: ld returned 1 exit status
    make[2]: *** [CMakeFiles/tvm.dir/build.make:1448: libtvm.so] Error 1
    make[1]: *** [CMakeFiles/Makefile2:253: CMakeFiles/tvm.dir/all] Error 2
    make: *** [Makefile:136: all] Error 2

Thanks!
