I think I got it, thanks Serge! It is actually very very close to what Fabrice has. I ended up running: cd $QSERV_DIR/admin scons after declaring local qserv in eups. I suspect it does not make much different though. Any opinions which version should be used to admin if developers have their own local qserv? --------------- Then, when I want to setup my environment in a new shell, I believe something like that is needed: cd ~/stack source loadLSST.sh setup qserv master-ga7082f1e02 # <-- use your version here That part is not documented at all, I think we should add it to README-devel.txt Jacek ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the QSERV-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=QSERV-L&A=1
