Build failures about mlir-dace HOT 4 CLOSED

Hi!
What branch and llvm-project commit are you using?
Have you tried building everything: cmake --build . or ninja?

from mlir-dace.

I'm running into precisely the same problem.

• OS: Ubuntu 22.04 LTS (amd64)
• apt install packages: build-essential, cmake, libstdc++-12-dev
• Source code: Fresh git clone with bundled llvm-submodule (so HEAD should be 5067939)
• Note: I don't use Ninja, just Make.

Steps on a fresh Linux account (ibug / /home/ibug):

• Clone repo: git clone https://github.com/spcl/mlir-dace.git --depth=1 --single-branch --recurse-submodules --shallow-submodules

• Build LLVM:

  cd mlir-dace/llvm-project
  mkdir build && cd build
  cmake ../llvm \
    -DLLVM_ENABLE_PROJECTS=mlir \
    -DLLVM_BUILD_EXAMPLES=ON \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_ENABLE_LLD=ON \
    -DLLVM_CCACHE_BUILD=ON \
    -DLLVM_ENABLE_ASSERTIONS=ON \
    -DLLVM_INSTALL_UTILS=ON
  cmake --build . --target check-mlir -j 24
  cmake --install . --prefix ~/.local

  Verify that ~/.local/lib/cmake/mlir exists and contains expected content.

• Build MLIR-DaCe:

  # starting from cd $HOME
  mkdir mlir-dace/build
  cd mlir-dace/build
  cmake .. \
    -DMLIR_DIR=$HOME/.local/lib/cmake/mlir \
    -DLLVM_EXTERNAL_LIT=$HOME/mlir-dace/llvm-project/build/bin/llvm-lit
  cmake --build . --target check-sdfg-opt -j 24

Now comes the error:

/home/ibug/mlir-dace/include/SDFG/Dialect/Dialect.td:25:22: error: Value 'useFoldAPI' unknown!
    let useFoldAPI = kEmitFoldAdaptorFolder;

/home/ibug/mlir-dace/include/SDFG/Dialect/Dialect.h:14:10: fatal error: SDFG/Dialect/OpsDialect.h.inc: No such file or directory
   14 | #include "SDFG/Dialect/OpsDialect.h.inc"

compilation terminated.

I just noticed that you have GitHub Actions set up, and interestingly I tried following lit-test.yml and had success with it. The main differences are

• I removed the cmake --install line from LLVM / MLIR build process.
• For MLIR-DaCe, I replaced -DMLIR_DIR=$HOME/.local/lib/cmake/mlir with -DMLIR_DIR=$HOME/mlir-dace/llvm-project/build/lib/cmake/mlir (i.e. using LLVM's build directory instead of "install" directory).
• I also gave up with Make and adhered to Ninja.

Thanks for the findings!
I will update the instructions on the readme to include the LLVM / MLIR build process.
