[Qgis-user] Encountering undeclared identifiers and classes during QGIS 3 build on macOS

[Mikhail Katychev]

Hello there,

Has anyone had any luck building QGIS 3 on macOS? I keep getting unknown
class names and identifiers that are very close to the expected ones such
as:

'IDataStream'; did you mean 'QDataStream'?

and

error: no type named 'Region' in namespace 'SpatialIndex'; did you
mean 'QRegion'?

as well as an indication that Rtree is unable to be found even when I
did a pip install rtree:
/Users/user/Downloads/QGIS-master/src/core/qgspointlocator.cpp:78:25:
error: use of undeclared identifier 'RTree'

Here is my cmake command arguments:

cmake ../CMakeLists.txt \
-DBISON_EXECUTABLE=/usr/local/opt/bison/bin/bison \
-DWITH_QTWEBKIT=false \
-DCMAKE_PREFIX_PATH=/usr/local/Cellar/qt/5.10.1 \
-DQSCINTILLA_INCLUDE_DIR=/usr/local/Cellar/qscintilla2/2.10.3/include/ \
-DQSCI_SIP_DIR=/usr/local/Cellar/qscintilla2/2.10.3/share/sip/Qsci \
-DQSCINTILLA_LIBRARY=/usr/local/Cellar/qscintilla2/2.10.3/lib/libqscintilla2_qt5.13.1.1.dylib

And here is my fatal error output log mostly referencing qgspointlocator.cpp:

Any help is appreciated.
