Dear List,
I need some help, i am stucked with building Tim Sutton's tutorial1
with qt. Do you have any idea about the solution?
I am trying to build Tim's first tutorial about qgis mapcanvas api on
macosx leopard with qtcreator ide, I have qgis1.0.0 installed.
- the tutorial has been checked out from the svn.
- Q_OBJECT is in the headers.
It's working with cmake, if I copy the following libs in the build
directory.
libgdal.1.dylib libgeotiff.1.dylib libjpeg.62.dylib libqgis_core.
1.0.dylib libxerces-c.28.dylib
libgeos.3.dylib libgif.4.dylib libpq.5.dylib libqgis_gui.1.0.dylib
libgeos_c.1.dylib libjasper.1.dylib libproj.0.dylib libtiff.3.dylib
If not, it gives error:
Scanning dependencies of target timtut1
[100%] Building CXX object CMakeFiles/timtut1.dir/main.o
Linking CXX executable timtut1
ld: file not found: @executable_path/lib/libproj.0.dylib
collect2: ld returned 1 exit status
make[2]: *** [timtut1] Error 1
make[1]: *** [CMakeFiles/timtut1.dir/all] Error 2
make: *** [all] Error 2
Perhaps the problem is that the qmake can't find the libs? They are
added to the .pro file, and they are in the g++ make command also.
Below you can find my .pro file and the build message. I have a lot of
undefined symbols an I don't know why.
What does these undefined symbols mean? I haven't included a lib?
Undefined symbols:
"QgsVectorLayer::select(int, bool)", referenced from:
QgsVectorLayer::qt_metacall(QMetaObject::Call, int, void**)in
moc_qgsvectorlayer.o
QgsVectorLayer::qt_metacall(QMetaObject::Call, int, void**)in
moc_qgsvectorlayer.o....
Thanks for your help in advance!
Best wishes!
