Installation in Macbook pro M2

[kenarab]

Hi guys!

I'm using a macbook pro M2 (AArch64)

I followed the instructions for installing concrete. I came quite far, but had a problem when concrete tries to link the binary

  Compiling tracing-subscriber v0.3.18
   Compiling concrete_parser v0.1.0 (/Users/kenarab/git/concrete/crates/concrete_parser)
   Compiling melior-macro v0.10.2
   Compiling melior v0.16.2
   Compiling concrete_driver v0.1.0 (/Users/kenarab/git/concrete/crates/concrete_driver)
   Compiling concrete v0.1.0 (/Users/kenarab/git/concrete/crates/concrete)
    Building [=======================> ] 270/271: concrete(bin)       

And the errors seems to be with a non compliant LLVM

LLVMDemangle" "-lm" "-lz" "-lzstd" "-lcurses" "-lxml2" "-lc++" "-lm" "-lz" "-lzstd" "-lcurses" "-lxml2" "-lc++" "-liconv" "-lSystem" "-lc" "-lm" "-L" "/opt/homebrew/Cellar/rust/1.77.1/lib/rustlib/aarch64-apple-darwin/lib" "-o" "/Users/kenarab/git/concrete/target/release/deps/concrete-57fd24f9222538ba" "-Wl,-dead_strip" "-nodefaultlibs" "-L/opt/homebrew/lib" "-L/usr/local/lib"

The cmake script for LLVM I used is this one

cmake -G Ninja ../llvm \
  -DLLVM_ENABLE_PROJECTS=mlir \
  -DCMAKE_BUILD_TYPE=Release \
  -DLLVM_TARGETS_TO_BUILD="AArch64" \
  -DCMAKE_OSX_DEPLOYMENT_TARGET=14.0

I built LLVM repo checking out tag llvmorg-17.0.6, as you stated LLVM 17 with MLIR enabled.
For building and installing custm LLVM have run this command

ninja build & ninja install

Thank you!

Did you try installing llvm with brew? Also did you setup the environment variables?

you can find the path to put to the env vars with brew --prefix llvm@17

Nope...

I built myself llvm with mlir enabled.

If I use brew installed llvm version as you suggested, the build process brokens much earlier, at mlir-sys just because llvm does not have mlir enabled. So the problem is elsewhere, an incompatibility with mlir implementation or version needed?

  Compiling mlir-sys v0.2.1

I'm sorry. Was my fault, I was not pointing the env variables to the right installation path. It worked ok using brew llvm version!
