Description Michael 2023-02-04 01:03:10 UTC

When installing catch2, CATCH_DEVELOPMENT_BUILD is turned on in the ebuild, which causes projects using catch2 to inherit compiler flags from it. This flag is meant for developers of catch2, and can cause problems when users of catch2 treat warnings as errors.
https://github.com/catchorg/Catch2/blob/devel/docs/cmake-integration.md#cmake-project-options

Reproducible: Always

Steps to Reproduce:
1. Install catch2 v3
2. Use catch2 from in a project that treats warnings as errors but does something to trigger -Werror=float-equal or -Werror=float-equal
3. Compile
Actual Results:  
Failure to compile your project

Expected Results:  
Successful compilation

The current workaround I have is to not use the catch2 in portage

There is no package called dev-cpp/catch2 in gentoo. Do you mean dev-cpp/catch?

Comment 2 Michael 2023-02-04 21:54:00 UTC

Yes, sorry, I meant dev-cpp/catch

Michael, This hacky cmake patch works for me at the moment until the ebuild is updated.
