What have I missed?

[PPParticle]

I have installed riscv-gnu-toolchain, riscv-pk and riscv-isa-sim. The reason why I installed this is I want to use rvv benchmark to test riscv-v-spec isa.

You can try this cmake command:
cmake -DLLVM_TARGETS_TO_BUILD="X86;RISCV" -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_USE_LINKER=gold -G Ninja ../llvm

[PPParticle]

I try what you have told.

You can try this cmake command: cmake -DLLVM_TARGETS_TO_BUILD="X86;RISCV" -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_USE_LINKER=gold -G Ninja ../llvm

It shows that

Thanks for your answers. It works.

$ cmake -DLLVM_ENABLE_PROJECTS="clang" -G Ninja ../llvm
$ ninja
$ sudo cmake --build . --target install
clang版本如下

How to solve the difference of version?

[Xinlong-Wu]

(this compiler supports 0.10)

use rv64gcv0p10 and try again

[PPParticle]

use rv64gcv0p10 and try again

It worked. However, it failed into another problems.
