Hi,
This is a heads-up regarding the impact of Go 1.24, now available in Fedora, and the subsequent mass-rebuild for Fedora 42. Over 200 packages are currently failing to build from source (FTBFS) [1] due to a stricter check introduced in Go 1.24 [2].
The failure occurs due to a stricter vet check requiring non-constant format strings to be explicitly handled. Affected builds fail with an error like:
non-constant format string in call to <function_name>
The failures typically occur during the %check phase, which is why "source-only" packages are also affected.
Fixing this issue is relatively simple, and some patches have already been submitted upstream [3][4]. However, addressing all affected packages downstream will likely take several months.
Best regards, Mikel
