[Bug] Default installation has LLVM errors

[MehdiTantaoui-99]

I installed tvm like instructed here: https://tvm.apache.org/docs/install/from_source.html

Once I run the test :

python -c "import tvm; print(tvm.__file__)"

Expected behavior

/home/ubuntu/tvm/python/tvm/__init__.py

Actual behavior

[13:07:34] /home/ubuntu/tvm/src/target/llvm/llvm_instance.cc:226: Error: Using LLVM 19.1.2 with `-mcpu=apple-latest` is not valid in `-mtriple=arm64-apple-macos`, using default `-mcpu=generic`

I've met the same problem as well. Have you resolved it?

[MehdiTantaoui-99]

I found a solution. You have to setup the LLVM config before compiling the library:

cd tvm/build/
vi config.cmake

Set set(USE_LLVM llvm-config) in the config.cmake file. Then run:

cmake ..
make -j$(nproc)

This solved the issue for me.

Thanks!!! I'll try.

I'm sorry, but I have a few more questions. According to https://tvm.apache.org/docs/install/from_source.html, I need to execute the "echo "set(USE_LLVM "llvm-config --ignore-libllvm --link-static")" >> config.cmake" command,. Do you mean changing this command to "echo "set(USE_LLVM llvm-config)" >> config.cmake"? I have done this, but the problems above remain.
