<p>We use the option only when <tt style="background: #ebebeb; font-size: 13px;">SOURCE_DATE_EPOCH</tt> is set, and we assume that a recent enough tar is available then. Basically we say that if reproducible builds are desired, the proper tools should be available.</p>

<p>Not sure I understand this question. The archive is created as part of the build process and then installed, on most Linux distributions into <tt style="background: #ebebeb; font-size: 13px;">/usr/share/kdevappwizard/templates</tt>.</p>

<p>Does this mean it won't be happy with <tt style="background: #ebebeb; font-size: 13px;">delete=atime,delete=ctime</tt>? And what does it mean that the package manager has its own tar, is this is a different tar than is used in the distribution itself?</p>

<p>The change is already committed, so I can't change the message anymore. I didn't know you were here, otherwise I would have added you earlier as reviewer.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R32 KDevelop</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D25494">https://phabricator.kde.org/D25494</a></div></div><br /><div><strong>To: </strong>aaronpuchert, kfunk, KDevelop, kossebau<br /><strong>Cc: </strong>bmwiedemann, kossebau, kdevelop-devel, hmitonneau, christiant, glebaccon, domson, antismap, iodelay, alexeymin, geetamc, Pilzschaf, akshaydeo, surgenight, arrowd<br /></div>
