Compiling error: conflicting declaration of C function

[pluviophilee]

我在按顺序执行以下指令时：
git clone https://github.com/OpenXiangShan/xfuzz.git
cd xfuzz && make init && make build && cd ..

git clone https://github.com/OpenXiangShan/riscv-arch-test.git
cd riscv-arch-test/riscv-test-suite
make build_I -j2
rm build/.elf build/.txt
cd ../..

git clone https://github.com/OpenXiangShan/riscv-isa-sim.git
make -C riscv-isa-sim/difftest CPU=ROCKET_CHIP SANCOV=1 -j16

export SPIKE_HOME=$(pwd)/riscv-isa-sim
export XFUZZ_HOME=$(pwd)/xfuzz
export NOOP_HOME=$(pwd)/rocket-chip
export CORPUS=$(pwd)/riscv-arch-test/riscv-test-suite/build

git clone -b dev-difftest --single-branch https://github.com/OpenXiangShan/rocket-chip.git
cd rocket-chip && make init && make bootrom
make emu XFUZZ=1 REF=$SPIKE_HOME/difftest/build/riscv64-spike-so LLVM_COVER=1 -j16

./build/fuzzer -f --max-runs 100 --corpus-input $CORPUS -- --max-cycles 10000

当执行到make emu XFUZZ=1 REF=$SPIKE_HOME/difftest/build/riscv64-spike-so LLVM_COVER=1 -j16时，编译报错error: conflicting declaration of C function ‘void v_difftest_ArchIntDelayedUpdate(uint8_t, uint64_t, uint8_t, uint8_t, uint8_t)’，请问您之前遇到类似问题吗？编译过程对编译器的版本有要求吗？

We are currently running on Ubuntu 22.04 with the clang compiler.

Which verilator and clang/gcc version are you using?

[pluviophilee]

verilator v5.020
clang v10.0.0-4ubuntu1
gcc v9.4.0
clang 我尝试了多个版本，包括clang 8和12，依然不行。

我的系统版本是Ubuntu20.04，因为我参考https://github.com/OpenXiangShan/difftest/blob/master/.github/workflows/main.yml#L267这个链接，里面说测试fuzz功能的环境是ubuntu20.04。

这个就比较奇怪了。我们的环境是github提供的干净ubuntu，所有的命令都在这个main.yml里面写着了。试一下make clean之后重新跑？

我也遇到了同样的错误，请问现在您解决了吗
