Hello Bill, Currently the "scons" install procedure only support a complete re-install. So you have to run : $ qserv-stop $ scons uninstall before each re-install of Qserv, if you want to be sure it always works. During development process, if you want to re-build only Qserv you can run next commands : $ qserv-stop # check previous command has done its job, $ /u1/bchick/sandbox2/qserv-master5/tmp/install/qserv-master.sh which will clean and re-install Qserv core (master/worker and common/) only. All this workarounds aren't documented and would require a lot of manpower in order to be all identified and solved. I don't think it is worth doing it now as the install procedure is currently moving to eups, indeed : - eups will solve most of these problems (but may add new ones ;-), so thanks for your usefull debugging) - all this kind of fixes added to "scons" install procedure might be deprecated by the new eups-based install procedure, Have a nice day, Fabrice On 01/09/2014 10:31 AM, Bill Chickering wrote: > Hi Fabrice - > > Thanks for the information.
