Re: [QGIS-Developer] Encountering undeclared identifiers and classes during QGIS 3 build on macOS

[Mikhail Katychev]

Dennis thanks for the reply, that issue was resolved by doing as you
suggested.
I however am completely unable to specify my SIP directory. There doesn't
seem to be any *cmake* parameters that allow me to point my PyQt5 SIP
directory.

I get
sip: Unable to find file "QtXml/QtXmlmod.sip"
make[2]: *** [python/core/sip_corepart0.cpp] Error 1
make[2]: *** Deleting file `python/core/sip_corepart0.cpp'
make[1]: *** [python/CMakeFiles/python_module_qgis__core.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs
[ 30%] Built target qgis_analysis
[ 30%] Built target qgis_vectorlayercachetest_autogen
[ 53%] Built target qgis_gui
make: *** [all] Error

When my Qt5Xml_DIR *ccmake* var is located in:
/usr/local/opt/qt/lib/cmake/Qt5Xml

And my actualy sip files are located in:
/usr/local/Cellar/pyqt/5.10/share/sip/Qt5

Running *FindPyQt5.py* gives me this output:
pyqt_version:050a01
pyqt_version_num:330241
pyqt_version_str:5.10.1
pyqt_version_tag:
pyqt_mod_dir:/usr/local/Cellar/python/3.6.4_3/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/PyQt5
pyqt_sip_dir:/usr/local/share/sip
pyqt_sip_flags:-t WS_MACX -t Qt_5_10_1
pyqt_bin_dir:/usr/local/Cellar/python/3.6.4_3/Frameworks/Python.framework/Versions/3.6/bin

The thing to point out is that I don't have a directory called
*/usr/local/share/sip*, only a Qt4 one: */usr/local/share/sip-qt4*. Should
I be creating a symlink pointing to that directory?

I have also tried this solution to no avail:
https://issues.qgis.org/issues/16034

Any suggestions on how to properly point to my PyQt5 directory would be a
huge help.

Thanks,
Mikhail

Hi,

You're using the system spatialite while you should use the brew one.

After is my cmake output.

Good luck!

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

[Mikhail Katychev]

Perhaps this is more relevant to the dev mailing list,

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 \
-DGRASS_PREFIX7=/usr/local/Cellar/grass7/7.2.2/grass-base \
-DBISON_EXECUTABLE=/usr/local/opt/bison/bin/bison \
-DWITH_QTWEBKIT=false \

-DQSCINTILLA_LIBRARY=/usr/local/Cellar/qscintilla2/2.10.3/lib/libqscintilla2_qt5.13.1.1.dylib
