Build Error: llvmlite 0.39.1 for Python 3.9.12 on Windows

Looking for help with this package that is failing to build in my project.

Runtime Details

  • Language - python 3.9.12
  • Platform - Windows

Failing Packages

  • llvmlite 0.39.1

According to the error:
CMake Error at CMakeLists.txt:3 (project):
ā€“ Configuring incomplete, errors occurred!

Visual Studio 15 2017 Win64

could not find any instance of Visual Studio.

VS2017 is missing on the build machine. Or did I configure this wrongly and everything needs to be build with a later VS version?


Welcome to the ActiveState Platform! Thanks for bringing this to our attention. Our engineers will investigate and report back on their findings.

In the meantime, if you are able to use llvmlite v0.38.0 (the previous release), I have confirmed that it will build successfully for Python 3.9.12 on Windows 10.

Hope that helps,

Thank you for the quick response!

I just change the version of llvmlite to 0.38.0 as recommended and the build succeeded. Assuming that this version is compatible with the other dependencies we can use it just fine.

best regards,
