[GitHub] [arrow] westonpace opened a new issue, #34891: [C++] MinGW builds failing because LLVM 16 is being installed but LLVM 15 is desired by gandiva
westonpace opened a new issue, #34891:
URL: https://github.com/apache/arrow/issues/34891
### Describe the bug, including details regarding any error messages, version, and platform.
In the most recent successful build I see `mingw-w64-x86_64-llvm-15.0.7-3` get installed. In more recent failing builds I see `mingw-w64-x86_64-llvm-16.0.0-1` get installed. This then fails below with...
```
2023-04-04T17:24:14.5277400Z CMake Warning at cmake_modules/FindLLVMAlt.cmake:30 (find_package):

```
However, I don't think we actually specify a version of llvm at all. It does not appear in https://github.com/apache/arrow/blob/main/ci/scripts/msys2_setup.sh
Is there a way to hard-code the llvm version that gets installed by msys? Should we upgrade gandiva to tolerate LLVM 16? Or can we do a bundled install of LLVM 15?

Ah, I see https://github.com/apache/arrow/issues/34768 so maybe this is not a concern then.
