Description Fedora Release Engineering 2026-07-21 18:28:55 UTC
erlang-jsx failed to build from source in Fedora rawhide/f45

https://koji.fedoraproject.org/koji/taskinfo?taskID=147849218


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_45_Mass_Rebuild
Please fix erlang-jsx at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
erlang-jsx will be orphaned. Before branching of Fedora 46,
erlang-jsx will be retired, if it still fails to build.

Comment 4 Peter Lemenkov 2026-08-07 11:24:44 UTC
Fixed in erlang-jsx-3.1.0-20.fc45.

The FTBFS was caused by an OTP 27 change where -0.0 and 0.0 are now distinct values. The test expected {float, 0.0} when decoding JSON "-0.0" but got {float, -0.0}. Fixed by applying upstream PR #162 which corrects the test expectation for -0.0 and adds an explicit 0.0 test case.
