[GitHub] [incubator-tvm] aarongreig opened a new issue #5734: LLVM 10 compatibility

aarongreig opened a new issue #5734:
URL: https://github.com/apache/incubator-tvm/issues/5734


   Hello
   
   I tried to build TVM linking against LLVM 10.0 and I got the following error:
   
   ```

   ```
   
   My CMake invocation was just `cmake -DCMAKE_BUILD_TYPE=Release -GNinja`. I used a custom `cmake.config` with `USE_LLVM` pointing to the llvm-config.

   Thanks for reporting the issue, Please open a new thread on https://discuss.tvm.ai/ for discussing trouble shooting issues. Noteably, the current CI uses llvm-10 from the llvm's apt snapshot and the project seems to built fine https://github.com/apache/incubator-tvm/blob/master/tests/scripts/task_config_build_cpu.sh#L32 It could be possible due to some lack of certain llvm features in your llvm-10 build, you can try to use the llvm-10 in the LLVM's apt snapshot instead
