Description Cristian Le 2025-07-16 15:13:53 UTC 
Dear package maintainer,

This is an automated bug created due to a FTBFS when rebuilding this package for the change proposal CMake: Use ninja generator by default.

The rebuild is being tracked in https://copr.fedorainfracloud.org/coprs/lecris/cmake-ninja/package/fann.

See https://fedoraproject.org/wiki/Changes/CMake_ninja_default for more information on how to make the package compatible.

More specifically, make sure you are using standard %cmake_* macros. If you find that there are hard dependencies on
the generator even after such transition, please ping me for closer investigation.

You can check the build locally following the instructions in the change proposal, or submit your build to the tracking
copr project.

Let me know if you encounter any issues, or need any other help.

Fann builds pass in F45 mock. Closing.

Ah. Sorry. I have not noticed this. So... Again.
Comment 4 Tomas Smetana 2026-02-27 14:08:42 UTC 
I merged the PR and pushed it also into f44, so hopefully it's all correct now. Thanks for your help.
