Hi, Nyall:

Thank you for your prompt reply.
I actually git out the source code from https://github.com/qgis/QGIS
 directly, but failed to build against python3.
So, is *daily master build* that you mentioned just *nightly build* from
http://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu

That is to say: https://github.com/qgis/QGIS master is different from  *nightly
build* from
http://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu ????


Thank you
