I investigated more to report it to upstream. On the rawhide, the gcc version is 11.0.0-0.7.fc34 According to the gcc 11 release note, the new warning -Wsizeof-array-div causing the error was added. https://gcc.gnu.org/gcc-11/changes.html > C family > New warnings: > -Wsizeof-array-div, enabled by -Wall, warns about divisions of two sizeof > operators when the first one is applied to an array and the divisor does not > equal the size of the array element. Here is the ticket with the examples. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91741 I will report it to the upstream, and let you know the result here. I am running the SRPM on the private-ruby-3.0 branch for f33 too just in case. ``` $ koji build --scratch --nowait --arch-override=x86_64 f33 ruby-3.0.0-0.1.20201204git1cfc6e7b7a.fc34.src.rpm https://koji.fedoraproject.org/koji/taskinfo?taskID=57179644 ``` -- Jun | He - His - Him _______________________________________________ ruby-sig mailing list -- ruby-sig@lists.fedoraproject.org To unsubscribe send an email to ruby-sig-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/ruby-sig@lists.fedoraproject.org
