The next bug deals with libcfs byteorder which breaks the build. I think we can backport the libcfs byteorder removal to handle that. </p> <p>The remaining problem I have never seen before. For the test application cascading_rw.c I was seeing missing build ID errors. So the way I worked around this problem was adding the following to lustre.spec.in.</p> <p>%undefine _missing_build_ids_terminate_build</p> <p>This enables rpms again but I don't know if that is the correct solution.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/22941/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/22941/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6387" title="Add Power8 support to Lustre" class="issue-link" data-issue-key="LU-6387"><del>LU-6387</del></a> tests: fix lp_utils build issues on Power8<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 0d68cfcf18f8f2118d5115fe3766d72c0630bb4d</p> <p>This also applies to ARM platforms.
