QGIS » QGIS Application

When building qgis 2.18.2, somewhere in the configuration the correct directory for @PyQt4@ does not get propagated everywhere:



In the directory where the build takes place, the files @build.cmake@ in the directories @python/CMakeFiles/[...].dir/@ contain @-I /usr/share/sip@ instead of the needed @-I /usr/share/sip/PyQt4@



Complete list of affected files for me (others may be affected as well when different build options are used), within the build directory:

<pre>

python/CMakeFiles/generate_sip_qgis._analysis_cpp_files.dir/build.make

python/CMakeFiles/generate_sip_qgis._core_cpp_files.dir/build.make

python/CMakeFiles/generate_sip_qgis._gui_cpp_files.dir/build.make

python/CMakeFiles/generate_sip_qgis._networkanalysis_cpp_files.dir/build.make

python/CMakeFiles/python_module_qgis__analysis.dir/build.make

python/CMakeFiles/python_module_qgis__core.dir/build.make

python/CMakeFiles/python_module_qgis__gui.dir/build.make

python/CMakeFiles/python_module_qgis__networkanalysis.dir/build.make

python/CMakeFiles/python_module_qgis__server.dir/build.make

</pre>



The build error which is encountered by this is:

<pre>

[...]

[ 97%] Generating gui/sip_guipart0.cpp, gui/sip_guipart1.cpp, gui/sip_guipart2.cpp, gui/sip_guipart3.cpp



sip: Unable to find file "QtXml/QtXmlmod.sip"

make[2]: *** [python/CMakeFiles/python_module_qgis__gui.dir/build.make:633: python/gui/sip_guipart0.cpp] Error 1

make[2]: *** Deleting file 'python/gui/sip_guipart0.cpp'

make[1]: *** [CMakeFiles/Makefile2:4257: python/CMakeFiles/python_module_qgis__gui.dir/all] Error 2

make: *** [Makefile:150: all] Error 2

</pre>



A quick fix is to change the content of those files after the @cmake@-run and before the @make@-run. For me, the following snipped does do it, executed within the build directory, after running @cmake@, before running @make@:

<pre>

_pyqt4_sip_dir="/usr/share/sip/PyQt4"

sed -i "s| /usr/share/sip | ${_pyqt4_sip_dir} |" python/CMakeFiles/{python_module_qgis__analysis,python_module_qgis__gui,python_module_qgis__server,generate_sip_qgis._analysis_cpp_files,python_module_qgis__core,generate_sip_qgis._core_cpp_files,generate_sip_qgis._gui_cpp_files,generate_sip_qgis._networkanalysis_cpp_files,python_module_qgis__networkanalysis}.dir/build.make

</pre>



Leading to this error, I build qgis the following way:

<pre>

mkdir build

cd build



_pyqt4_sip_dir="/usr/share/sip/PyQt4"



cmake -G "Unix Makefiles" ../ \\

-DCMAKE_INSTALL_PREFIX=/usr \\

-DQGIS_MANUAL_SUBDIR=share/man \\

-DENABLE_TESTS=FALSE \\

-DCMAKE_SKIP_RPATH=TRUE \\

-DPYTHON_EXECUTABLE=/usr/bin/python2 \\

-DWITH_INTERNAL_{DATEUTIL,FUTURE,HTTPLIB2,JINJA2,NOSE2,OWSLIB,PYGMENTS,PYTZ,QWTPOLAR,SIX,WEBKIT_BINDINGS,YAML}=OFF \\

-DWITH_INTERNAL_{QEXTSERIALPORT}=ON \\

-DPYQT4_SIP_DIR="${_pyqt4_sip_dir}" \\

-DWITH_SERVER=ON \\

-DWITH_GLOBE=ON \\
