How to compile dynamic library for backend riscv

[xysxs]

I want to deploy the mnist-lenet network to the riscv backend, I executed the following command
onnx-mlir -O3 --EmitLib --mtriple=riscv64-unknown-linux-gnu mnist_lenet.onnx
but it reported an error
/usr/bin/ld: mnist.o: Relocations in generic ELF (EM: 243) /usr/bin/ld: mnist.o: Relocations in generic ELF (EM: 243) /usr/bin/ld: mnist.o: Relocations in generic ELF (EM: 243) /usr/bin/ld: mnist.o: error adding symbols: file in wrong format collect2: error: ld returned 1 exit status c++ mnist.o -o mnist.so -shared -fPIC -L/home/xy/Desktop/onnx-mlir/build/Debug/lib -lcruntime Error message: Program path: /usr/bin/c++ Command execution failed.
I think this is because the static library architecture is x86 in /build/Debug/lib

If only producing .obj files like this:
onnx-mlir -O3 --EmitObj --mtriple=riscv64-unknown-linux-gnu mnist_lenet.onnx
Then when generating the executable file later, do I still need to link the static library? Will an error be reported?
what should I do?
