[Qgis-developer] QGIS setup with Qt 5 on mac

Thu Nov 17 17:55:55 PST 2016

Hi,

Quick update. Success! I've finally built QGIS 3 master branch off of
unmodified Homebrew dependencies, though had to edit several bits of source
code and pull some hair out.

QGIS version: 2.99.0-Master
QGIS code revision: 6727ea7
Compiled against: Qt 5.7.0
Running against Qt: 5.7.0
Compiled against GDAL/OGR: 2.1.2
Running against GDAL/OGR: 2.1.2
Compiled against GEOS: 3.5.0-CAPI-1.9.0
Running against GEOS: 3.5.0-CAPI-1.9.0 r4084
PostgreSQL Client Version: 9.6.1
SpatiaLite Version: 4.3.0a
QWT Version: 6.1.3
PROJ.4 Version: 493
QScintilla2 Version: 2.9.3
This copy of QGIS writes debugging output.

and Python 3.5.2.

It's take me a bit more time to commit proper changes, create the qgis3-dev
formula and add the docs for:

https://github.com/qgis/homebrew-qgisdev

Is anyone else already developing QGIS 3 master on Mac?
