Then run the Windows build on the RAM-drive. That should speed things up. I do that here for some of my builds, and it makes a massive difference. In fact, I could probably get permission to host such a machine here at work, provided that the build slave does not soak up too much network bandwidth (I'm in South Africa, bandwidth is expensive).

Who owns the hardware? Perhaps I (or the company I work for) can contribute to the cost of (a) or (b).

(provided master has not been broken... see how that brokenness is contagious ?) code, make, fix, make, fix, make.. commit, git status (to veryfy that you did not miss anything in the commit, if necessary:git commit --amend) Note that the 'make' above do not have to be global make... except for a last one when you ar ready to pull -r, you can make the module you changed (if it is a old-dmake module you need to build and deliver) Then pull -r if you have conflict resolve them and definitely make if you have no conflict, eyeball the change that got in and make a call about the likelihood of a 'silent' conflict. At that point, if you want to be very safe: make clean/autogen/make again... but if you don't an push, you still will be very unlikely to have broken master. Push ... AND keep an eye on the tinderboxes. usually within 20 minutes you should have the result of a tinderbox run with your pushed change in it (except windows so far). <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://tinderbox.libreoffice.org/MASTER/status.html">http://tinderbox.libreoffice.org/MASTER/status.html</a> Norbert _______________________________________________ LibreOffice mailing list <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:LibreOffice@lists.freedesktop.org">LibreOffice@lists.freedesktop.org</a> <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/libreoffice">http://lists.freedesktop.org/mailman/listinfo/libreoffice</a> </pre> </blockquote> </blockquote> </body> </html>
