On an up-to-date OS X Sierra, using QGIS git master and MacPorts' QT5 following David Marteau's instructions at https://www.3liz.com/blog/rldhont/index.php?post/2017/06/01/How-to-build-qgis-on-OSX-with-MacPort), I set the compilers as suggested in INSTALL:

export CC=/usr/bin/llvm-gcc
export CXX=/usr/bin/llvm-g++

The build was successful, but install complains. I take it these codecs are not required?

Install finds QT5, but looks for PyQt4 instead of PyQt5 -- py36-pyqt5 @5.8.2_0 is installed:

How can I tell install to look for PyQt5?

What were your cmake options? I have found that


ameliorates some issues (though I am not 100% satisfied it makes everything go away).

Further, I suspect some changes need to be made in /mac/cmake/1qt.cmake.in (PyQt version 4 seems to be hard-coded in)

Great, thanks. I've been using this, from David Marteau with supplements:

cmake $(CMAKE_OPTS) \
        -DWITH_ASTYLE=ON \
        -DWITH_SERVER=ON \
        -DPOSTGRES_CONFIG:FILEPATH=/opt/local/lib/postgresql96/bin/pg_config \
        -DLIBZIP_INCLUDE_DIR:PATH=/opt/local/include \
        -DLIBZIP_CONF_INCLUDE_DIR:FILEPATH=/opt/local/lib/libzip/include \
        -DLIBZIP_LIBRARY:FILEPATH=/opt/local/lib/libzip.dylib \
        -DEXPAT_INCLUDE_DIR:PATH=/opt/local/include \
        -DEXPAT_LIBRARY:FILEPATH=/opt/local/lib/libexpat.dylib \
        -DSQLITE3_INCLUDE_DIR:PATH=/opt/local/include \

        -DQCA_LIBRARY:FILEPATH=/opt/local/libexec/qt5/lib/libqca-qt5.dylib \
        -DQSCINTILLA_INCLUDE_DIR:PATH=/opt/local/libexec/qt5/include \
        -DQSCINTILLA_LIBRARY:FILEPATH=/opt/local/libexec/qt5/lib/libqscintilla2_qt5.dylib \
        -DQTKEYCHAIN_INCLUDE_DIR:PATH=/usr/local/include/qt5keychain \
        -DQTKEYCHAIN_LIBRARY:FILEPATH=/usr/local/lib/libqt5keychain.dylib \
        -DQT_LRELEASE_EXECUTABLE:FILEPATH=/opt/local/libexec/qt5/bin/lrelease \

The "-DWITH_GRASS7:BOOL=ON" option fails to find grass7 installed by MacPorts in /opt/local/share/grass-7.2.2.

As you say, pyqt4 is hardcoded in a few places in mac/cmake/1qt.cmake.in:

QGIS-2.99$ grep -i pyqt4 mac/cmake/1qt.cmake.in
            # MESSAGE (STATUS "ditto ${QARCHS} \"${PYQT4MOD}\" \"${QGISPYDIR}/${MODSUBPATH}\"")
        MESSAGE (STATUS "  PyQt4 module ${MODNAME} not found")
        EXECUTE_PROCESS (COMMAND ditto ${QARCHS} "@[email protected]/${PU}" "${QBINDIR}/")
    EXECUTE_PROCESS (COMMAND sed -E "s, /.*/PyQt4/uic/pyuic.py, \"\$(/usr/bin/dirname \"\$0\")/../../Resources/python/PyQt4/uic/pyuic.py\"," "@[email protected]/pyuic4" 

Is the goal to support both pyqt4 and 5?
