Steps to Reproduce:
1: ppc-koji build --scratch f21 ruby-2.1.1-19.fc21.src.rpm

Comment 2 Dan Horák 2014-05-15 12:12:31 UTC
I think this is a known problem when you run the build on old kernel. There are new SEEK_* options in headers (found by configure and used in build), but they are not supported by the old kernel.

patch to check if the kernel supports SEEK_DATA/SEEK_HOLE

taken from http://mla.n-z.jp/~w3ml/w3ml.cgi/ruby-changes/msg/33585 and

Tests succeeded on ppc and ppc64, but fail on the primary archs for an unrelated reason

Comment 4 Karsten Hopp 2014-05-15 16:05:43 UTC
hmm, close but not quite there yet. PPC failed later on with a statfs error.

revised lseek patch

Scratch builds with this patch succeeded on PPC (RHEL-6 koji builder with kernel 2.6.32) and on primary archs with a much newer 3.x Fedora kernel.


Comment 6 Vít Ondruch 2014-05-19 09:54:57 UTC

Thanks for the patch. However, I hesitate to apply this patch and carry it in Fedora forever. Would you mind to propose this patch to Ruby upstream or should I?

Comment 7 Karsten Hopp 2014-05-27 09:36:21 UTC
as this is a stripped down version of the upstream patch, I'd expect that this patch becomes obsolete with the next ruby release. So there's no need to bounce that back to upstream, they are aware of the issue and fixed it already in ruby-trunk

Comment 8 Jaroslav Reznik 2015-03-03 15:48:48 UTC
